Welcome to the Companion Web Site

Welcome to the Lotus Notes® and Domino 6 Programming Bible Web Site!
The Lotus Notes® and Domino 6 Programming Bible is a collaboration between Brian Benz and Rocky Oliver, two well-known Notes and Domino professionals.

The book is a comprehensive guide to programming concepts and techniques for Lotus Notes and Domino 6. It covers advanced programming techniques used in the development of Notes and Domino applications. Brian and Rocky weave together concept explanations, working examples, and reference information in a logical progression, from basic concepts to advanced topics.

The material in the book is therefore useful for all developer skill levels, from beginning to advanced. The material does not assume any previous exposure to Notes and Domino, but the presentation of the examples and techniques is not “dumbed down” either. The authors understand the fundamental concepts of Notes and Domino better than most advanced developers, and they have extensive experience writing about and teaching these topics. They make the material understandable for beginners while at the same time “shedding new light” on it for experienced professionals.

The book makes extensive use of examples, which are — as much as possible — constructed incrementally. In other words, examples build on one another within a chapter, as well as across chapters. By following the examples, readers see several applications developed from scratch, with illustrative features added in contexts that are themselves instructive. Some of the examples are provided in the context of “toolbox” applications, and many of the tools will be of interest to Domino Administrators as well as developers.

The Introduction will tell you more information about how the book and the site are structured. Parts I-V and Part VI-XI list the description and outline for each chapter of the book. Downloads, examples, and updates are also available.

Introduction

Introduction
The book begins with a chapter that provides an overview of the book’s format, followed by a What is Notes and Domino?” chapter that discusses the technology, its purposes, its positioning against other technologies, and its history. The next chapter shows a very simple application. The next two chapters provide a detailed look at storage and programming components of a Notes database. We've broken the content up into two sections: Parts 1-5 and Parts 6-10. Parts 1-5 contain Chapters 1-28 and Parts 6-11 contain Chapters 29-58.

Parts I-V

Parts I-V

Part I — Introduction to Lotus Notes and Domino.

In Part I, we provide a general introduction to Lotus Notes and Domino. We briefly cover the history and evolution of the products and their uses. Next, we describe a very simple Notes and Domino application. We introduce the NSF file, which is the foundation of all Notes and Domino applications. Finally, we briefly describe the building blocks that Notes and Domino developers put into NSF files to create applications.

Outline:

  • The NSF file
  • Inside the NSF
  • Finding a note
  • Inside a note

Chapter 4 — Application Building Blocks
by Rocky Oliver

Domino databases are made up of data, and many design elements enable you to build applications that work with that data. Over the years, more of these design elements, such as Web-enabled databases, data integration, and so on, have been added to the database structure to support the ever-changing demands of the market. This chapter introduces you to these application building blocks, providing a brief introduction to each element.

Outline:

  • Introducing design elements
  • Understanding data entry and display elements
  • Working with navigation elements
  • Working with code elements
  • Working with resource elements

Part II — Domino Designer

The second part covers the Domino Designer program. One chapter provides a walk-through of the Integrated Development Environment features for developing each type of design element. Another chapter discusses how to organize projects in the Designer and manage templates.

Chapter 5 — The Designer IDE
by Brian Benz

In earlier versions of Lotus Notes, user and designer components were built into the same client software. With the release of Lotus Domino R5, and extended with Domino 6, Domino Designer has been a separately installable, separately executable product. With Domino Designer, developers now have separate end-user and developer environments, each organized for efficiency of the task-at-hand. This chapter presents the major elements of the Designer IDE to alert you to all its features and their functions.

Outline:

  • Navigating the Designer IDE
  • Domino design elementsCoding and debugging features
  • Sharing resources
  • Developing Domino applications using Web
  • DAV-compliant tools
  • DXL utilities
  • Previewing your design

Chapter 6 — Managing and Deploying Application Projects
by Richard Schwartz

Most programmers are used to working with a development environment that organizes projects containing source files, object files, and executable files. Programmers who work with the Notes C and C++ APIs do work this way, but most Notes and Domino development doesn’t use those tools. So, for the most part, source files, executables, and separate data files or database systems are foreign concepts to Notes and Domino programmers. This chapter explains the concepts with which Notes and Domino work to organize projects and deploy applications.

Outline:

  • Understanding projects, applications, and databases
  • Using templates
  • Working on multidatabase projects
  • Working on a development team
  • Deploying applications

Chapter 7 — Standard Templates
by Richard Schwartz

Notes and Domino provide powerful tools for the development of custom applications. Many Notes and Domino users, however, are totally unaware of this fact. They know only that their company uses Notes and Domino for e-mail, calendaring, and address books. Others know only that it provides e-mail and online discussion facilities. What they don’t know is that IBM engineers have built all the most popular features of Notes and Domino using the same programming tools that are available to every Notes and Domino programmer for custom applications.The features of Notes and Domino that end-users know best and that are responsible for much of the popularity of the products are built from ordinary Notes and Domino templates. Every Notes and Domino programmer can examine those templates to learn how those features work.Notes and Domino ship with more than 30 different template files. Many are employed in system administration tasks and are unfamiliar to most users, while others are extremely useful for learning how to develop your own applications.This chapter briefly describes the templates that are most familiar to end users: the Mail template, the Personal Address Book template, the Discussion template, and the Document Library templates.

Outline:

  • Using a Mail template
  • Using the Personal Address Book template
  • Using the Discussion template
  • Using the Document Library templates

Part III — Application Architecture.

The third part covers the structural elements of a Notes and Domino application. Chapters cover views, database security, navigational design elements, advanced form design, database launch and other properties, and sharing code through subforms, shared fields, and code libraries.

Chapter 8 — Page and Form Basics
by Richard Schwartz

Pages and forms are design elements used to create formatted data displays in Notes and Domino. If you are familiar with HTML, it is important to understand that it was invented after Notes, so some Notes and Domino terminology does not match up precisely with what most Web programmers would expect. In HTML, a form is a portion of a page that can contain input elements. In Notes and Domino, a form is a design element used for displaying data from documents and entering new data into documents, and a page is a design element used only for displaying data. Pages are typically used for displaying online help, for menus used to navigate through the features of an application, or for lists of links. This chapter introduces you to the basics of creating pages and forms, and explains how to use them to build your Domino applications.

Outline:

  • Creating pages
  • Creating forms
  • Formatting text on pages and forms
  • Data access through fields on forms

Chapter 9 — Views and Folders
by Rocky Oliver

Download the example files

Views and folders provide a robust way to display groups of documents ordered in a meaningful way. But views provide more functionality than just viewing documents. Views are often used as the starting point for workflow automation, for programmatically accessing documents, for providing calendar-based grouping of documents, and for much more. Views are one of the most powerful design elements in a Domino database, and this chapter introduces you to some powerful techniques for getting the most out of your views.This chapter will not teach you the basics of building a view — that’s what the Domino 6 Designer Help is for. What this chapter does do is build upon that help file and the basics it teaches, and helps you get the most out of your views and folders in both your Notes and Web-based applications.

Outline:

  • Learning how views work
  • Optimizing your viewsMaking views more powerful than ever

Chapter 10 — Database Security
by Rocky Oliver

One of the cornerstones of Lotus Notes and Domino is security. Unlike other applications, where security is an obvious afterthought, Notes/Domino is built from the ground up with a rock-solid security infrastructure in place. This chapter helps you understand this security structure and what it means to your applications. You are introduced to server security, database security, and document security.

Outline:

  • Security starts at the server
  • The database ACL
  • Document-level access
  • Field-level encryption(Non)security through obscurity
  • Plan your security from the beginning

Chapter 11 — Framesets and Outlines
by Brian Benz

Outlines and framesets augment the Menu and Action Bar navigational features that are built into Notes client, and add more options for control and display of an application UI, especially on the Web. This chapter focuses on the capabilities of using framesets and outlines in Notes client and Web applications, as well as tips, tricks, drawbacks, and alternatives for each feature.

Outline:

  • About Navigators
  • Introduction to framesets and outlines
  • Outlines Framesets
  • Domino Web Application Navigation using outlines and framesets

Chapter 12 — Advanced Form Design
by Rocky Oliver

Download the example files

Chapter 8 introduced you to the basics of designing a form. This chapter shows you how to take your form design to the next level, helping you exploit forms in ways you may never have imagined. This chapter exposes you to various design elements that you can use with forms. Some practical uses are provided as examples, which are broken down so you can use these techniques in your applications.

Outline:

  • Element integration overview
  • Tables Sections Hide-whens Layers Buttons and action hotspots
  • Form actions Image resources Embedded views
  • Advanced form design examples

Chapter 13 — Database Properties
by Richard Schwartz

Developing Notes and Domino applications is not just a matter of designing pages, forms, views, and other design elements. As discussed in Chapter 10, security settings are another important part of the application. In this chapter, you examine many other database-wide settings that help determine aspects of an application’s behavior. The database properties dialog provides a wealth of information about your database, and allows you to customize many of its behaviors.

Outline:

  • Applying database settings
  • Accessing storage information
  • Exploring print settings
  • Exploring design settings
  • Exploring launch settings
  • Exploring full-text search settings
  • Exploring advanced settings

Chapter 14 — Sharing Code with Libraries
by Rocky Oliver

Download the example files

Script libraries are one of the most handy design elements in Lotus Notes and Domino. Script libraries enable you to reuse code in multiple design elements throughout your database application. Three types of script libraries exist: LotusScript libraries, JavaScript libraries, and Java libraries. This chapter doesn’t cover all the basics of using a LotusScript library — that discussion is covered in the Domino 6 Designer help. This chapter concentrates on more useful techniques for creating and using LotusScript libraries, and provides examples along the way.

Outline:

  • Tips for creating a LotusScript library
  • Going deep instead of wide
  • Segmenting your libraries
  • Commenting your libraries
  • Chaining librariesExamples

Part IV — Automating Applications.

The fourth part covers programmable elements of an application. Individual chapters are devoted to field formulas, actions and events of various types, agents, Web programming, e-mail integration, security, and workflow. The actual programming shown in examples within this part is fairly simple, but it illustrates all the major components and built-in capabilities of the Notes and Domino environment.

Chapter 15 — Formulas in Forms and Views
by Rocky Oliver

Download the example files

The Formula language is extremely powerful, as discussed in Part V. This chapter concentrates on the various places you can use the Formula language in forms and views. You also learn helpful tips and techniques for using the Formula language in your forms and views to get the most out of your applications.

Outline:

  • Using Formulas in forms
  • Formulas in form events
  • Formulas in fields
  • Miscellaneous uses
  • Formulas in views
  • Formulas in view events
  • Column formulas
  • Hide-when formulas

Chapter 16 — Actions, Buttons, and Action Hotspots
by Rocky Oliver

Download the example files

A user can execute a predefined set of code by clicking an action button (otherwise known as an action), a button, or an action hotspot. Actions are available in forms and views, while buttons and action hotspots are available in forms and pages. Each item is an agent that you call by clicking it instead of choosing it from a menu. What you can do in an agent, you can do in an action or button. You can use each of these items in various ways, many of which are described in this chapter. Actions and buttons can contain simple actions, LotusScript, formulas, and JavaScript. Additionally, in Notes/Domino 6 you can place client-specific code in each — one set of code for the Notes client and one set of code for Web browsers. Most examples in this chapter use the Formula language because it is the easiest to use; however, many examples in the book use other languages. The Bubba's Shrimp Ordering System example in Chapter 12 makes extensive use of LotusScript.

Outline:

  • Action buttons
  • Using action buttons in forms
  • Using action buttons in views
  • Buttons and action hotspots

Chapter 17 — Form, View, and Database Events
by Rocky Oliver

Download the example files

An event occurs when an object, such as a form, does something. In object-oriented programming (OOP) languages such as LotusScript, there are places to put code that is executed when an event occurs, usually before (Query) or after (Post) the event takes place. Therefore, you can write code in these Query and Post events, and that code is executed before and/or after the event occurs, respectively. This chapter explains why events are important and what you can do with them. An entity known as an object model represents the contents of a database. An object model is a way to represent the data of a database as things, or objects, that you can access and work with. These objects include ways to access the data in the object (through properties) and ways to take action against the object (through methods). Objects that exist in the UI also perform actions — they are opened, closed, refreshed, saved, and so on. When an object does something, it’s an event. You sometimes have the opportunity to bind code to these events, either right before or right after the event occurs. Creating an application that performs based on when object events happen is known as event-driven programming. LotusScript, JavaScript, and Java are object-oriented languages that are used in event-driven programming. Even the Formula language is event-driven (though it really isn’t an object-oriented language), as you can use formulas in events as well as the other languages mentioned.

Outline:

  • Understanding form events
  • QueryOpen
  • PostOpen
  • QueryModeChange,PostModeChange
  • QueryRecalc, PostRecalc
  • QuerySave, PostSave
  • QuerySend, PostSend
  • QueryClose
  • Understanding view events
  • New event:
  • InViewEditDatabase events
  • PostOpen
  • QueryDocumentDelete, PostDocumentDelete
  • QueryDocumentUndelete
  • QueryDragDrop, PostDragDrop
  • QueryDropToArchive, PostDropToArchive

Chapter 18 — Agents
by Rocky Oliver

Agents are small, mini-programs that you can create in Notes and Domino to perform tasks. An agent can be initiated by a user, scheduled, triggered when a certain event occurs, or initiated from a browser. Agents can run on the server or run locally, and can run as the person who called it or the person who last saved it. Agents are an extremely powerful component of Notes and Domino development.This chapter introduces you to various agent parameters, types, and uses. Tips and tricks are provided along the way, as well as cross-references to other examples in the book. It concentrates on agents in the Notes client and from a server. As always, this chapter is not meant to rehash the material in the Domino 6 Designer help; it simply offers some insight into the use of agents and provides some tips for their usage.

Outline:

  • Understanding agents
  • Front-end versus back-end
  • Setting agent permissions
  • Understanding agent targets
  • Setting agent triggers
  • Location, location, location
  • Agents that execute from the Notes client
  • Agents that execute based on an event
  • Agents that execute on a schedule
  • Agents executed from a Web browser
  • Logging errors and troubleshooting
  • Agent testing
  • Agent logging
  • Remote debugging
  • Agent troubleshooting references

Chapter 19 —Web Applications
by Brian Benz

Download the example files

Because of Domino's advanced container model that naturally organizes and manages unstructured data, collaborative application capabilities, integrated development environments, and support for e-mail integration, Domino is a natural choice for a Web application server. This chapter introduces Domino’s advanced Web capabilities by demonstrating Domino features for collaborative Web applications and Web sites and illustrates these features by starting to develop the prototype Web site that is used throughout the rest of the book.

Outline:

    • Introducing the Web site prototype
    • Using Web design elements
    • Understanding Web navigation
    • Understanding Web page display
    • Understanding Web data entry
    • Using shared fields

Chapter 20 —Mail-Enabled Applications
by Brian Benz

Download the example files

Aside from the integrated Domino Designer application development environment outlined in Chapter 5, and the ability to organize unstructured data into Web applications covered in Chapter 19, Domino has another important feature that makes it a world-class application platform: easy e-mail integration. In this chapter, we cover the advanced e-mail integration options for Domino and Web applications, including creating and managing mail-in applications and generating e-mail newsletters. Developers will learn how to add an opt-in e-mail list to a Domino Web site, how to create an application to manage subscriptions, changes, and removals from the e-mail list, and how to develop an application to organize and distribute e-mail newsletters.

Outline:

  • Options for e-mail integration
  • E-mail options for forms
  • Simple actions for sending e-mail
  • E-mail options for @functions
  • E-mail options using LotusScript
  • E-mail options using Java Example:
  • An e-mail newsletter mailing application

Chapter 21 — Document Security
by Rocky Oliver

Download the example files for chapters 21 and 22.

Notes/Domino is one of the most secure applications available for storing, sharing, and working with sensitive information. Chapter 10 reviewed database security and mentioned document security. Because you store your information in documents, documents have the most security options available. This chapter helps you better understand the options available for securing your information.

Outline:

  • Reviewing database security
  • Choosing document-level access
  • Understanding author and reader names fields
  • Encrypted fields
  • Document locking

Chapter 22 — Workflow Management
by Rocky Oliver

Download the example files for chapters 21 and 22.

Notes and Domino make a great container for information. Notes has many tools available out of the box that help you work with, manipulate, and manage your information. But you may want to extend the interaction with the user from just the things that a user initiates to an exchange between the user and the application, even to the point where the application initiates the interaction. A great deal of the power of Notes/Domino resides in its ability to initiate an interaction with a user — routing documents or informing users about things going on with their information in an application. In short, one of the strengths of Notes/Domino is its ability to create and manage automated workflow in an application.This chapter introduces you to two types of workflow in an application, and then provides an example application that you can play with and examine to gain ideas for your own applications.

Outline:

  • Understanding workflow concepts
  • Understanding approval workflows
  • Using document locking
  • Integrating workflow: An example

Part V — Formula Language Techniques.

Part V covers the Formula language, which was the original programming language for Notes versions 1, 2, and 3.

Chapter 23 — Introduction to the Formula Language
by Rocky Oliver

Lotus Notes provides a rich set of programming tools in an integrated environment. The release of Notes/Domino 6 has added to that toolkit by enhancing existing tools or languages, such as LotusScript and Java, and new tools have also been added, such as integrated XML support. With the variety of choices available, it is easy to overlook the venerable granddaddy of Notes programming languages, the Formula language. But overlooking the Formula language as an integral part of your toolkit is a mistake. This chapter introduces you to the Formula language, explains the basics of its use, and shows you some advanced techniques for enhancing your Notes/Domino applications. The remaining chapters in Part V expand your knowledge of the Formula language

Outline:

  • The Formula language defined
  • Why use the Formula language?
  • Where and when to use the Formula language

Chapter 24 — Working with @Functions
by Rocky Oliver

@Functions are the core components of the Formula language. In fact, they were the first components of the Formula language, and originally the only components. Beginning with a simplistic 93 core @Functions in Notes Version 1 — all of which are still usable today — the Formula language in Notes/Domino 6 now includes 256 documented @Functions. Now, we’re not going to attempt to cover all of them here (that’s what the Help file is for); however, you will be introduced to programming techniques for getting the most out of @Functions, and you will be introduced to some of the more useful @Functions. Subsequent chapters in this section dive into the details of using particular @Functions for specialized tasks.

Outline:

  • Working with @Functions
  • Useful @Functions for Notes applications
  • Useful @Functions for Web applications

Chapter 25 — Introduction to @Commands
by Rocky Oliver

Chapter 24 took a fairly deep dive into @Functions. In this chapter, you explore the companions to @Functions in the Formula language, the @Commands. In reality, @Commands are just another type of @Function; however, they are different from other @Functions because virtually all of them are closely tied to things in the user interface (UI). @Commands enable you to take action against things in the UI, and these actions generally map to menus in Notes. This chapter serves as a primer on how to use @Commands in your applications. The chapter introduces techniques for working with @Commands, and then dives into some of the more useful @Commands that are available to you.

Outline:

  • Working with @Commands
  • Useful @Commands for Notes applications
  • Useful @Commands for Web applications

Chapter 26 — Using the Formula Language to Retrieve Data
by Rocky Oliver

The earlier chapters of Part V introduced you to the Formula language. You learned some general guidelines for use and explored how the Formula language can help you in your development efforts. This chapter delves into some ways you can retrieve and work with data using the Formula language, concentrating on various uses of @DbColumn and @DbLookup. The chapter begins by introducing the basic usage of @DbColumn and @DbLookup for retrieving Notes data, and then explores how to use these two functions to retrieve data from external sources using ODBC.

Outline:

  • Introducing @DbColumn and @DbLookup
  • Retrieving Domino data using @DbColumn and @DbLookup
  • Retrieving ODBC data using @DbColumn and @DbLookup

Chapter 27 — User Interaction Through the Formula Language
by Rocky Oliver

One of the most useful features of the Formula language is the ability it gives you to interact with users. You have a great deal of flexibility at your fingertips for informing users, gathering information from users, or interacting with users. The three main @Functions used to interact with users are @Prompt, @PickList, and @DialogBox. These functions have many optional parameters, and using them is an art form in and of itself.This chapter introduces you to some useful ways to work with @Prompt, @PickList and @DialogBox, and provides some concrete examples about how to get the most out of them. @Prompt allows you to provide information to a user, or ask the user to enter or choose information. @PickList allows you to use a view as a type of dialog box and enables the user to choose one or more documents. @DialogBox is the most flexible of all — it allows you to use a form as the basis for a dialog box, providing you virtually unlimited customization choices.

Outline:

  • Working with @Prompt
  • Using @Prompt Programming with @Prompt
  • Programming with @PickList
  • Using @DialogBox

Parts VI-XI

Parts VI-XI

Part VI — LotusScript Language Techniques.

Part VI covers LotusScript, a scripting language similar to Visual Basic for Applications, which was added in Release 4. Part VI also includes information about working with other desktop applications via COM and OLE, as well as working with the C API from LotusScript.

Chapter 29 — Introduction to LotusScript
by Rocky Oliver

Even though Lotus Notes was an innovative, flexible, and powerful collaboration platform prior to Release 4, it took a huge step forward with the release and the introduction of LotusScript. Originally introduced in Lotus Improv for Windows (an innovative but misunderstood spreadsheet product) in 1993, Lotus quickly decided to add a common scripting language to all of its products. LotusScript support was added to Lotus Notes Release 4 in January 1996. But what exactly is LotusScript? This chapter introduces you to the LotusScript language, and a couple of the concepts it is built on — object-oriented programming and event-driven programming. You are then introduced to other basic LotusScript concepts, such as syntax, classes, and objects, and the Domino Object Model.

Outline:

  • Introduction to LotusScript
  • Introducing LotusScript syntax basics
  • Understanding data types in LotusScript
  • Understanding subroutines and functions in LotusScript
  • Using classes and objects in LotusScript
  • Using the LotusScript debugger

Chapter 30 — Working with the Domino Object Model in LotusScript
by Rocky Oliver

Download the example files.

You now have a working knowledge of how LotusScript works, and a basic understanding of classes and objects. This chapter takes that general knowledge and applies it to the LotusScript classes used to define the Domino Object Model.

The Domino Object Model (DOM) is an object model that represents the application programming interface (API). The API provides the interface for working with Domino databases. At its core, it is written in C. The other languages available in Domino — LotusScript, Java, C++, the Formula language, and even JavaScript — all provide higher-level access to the API itself and the object model it represents. Therefore, the features and functions available for working with Domino databases are relatively the same for all programming languages. Of course, some languages offer only a subset of functionality — for example, Java offers access to only the back-end portion of the object model (more on that later) — but the interfaces that do exist between the different languages are all used in relatively the same way, with a few syntactical differences.

The DOM is broken down into two major areas: @ UI, or front-end classes, and data, or back-end classes.

Outline:

  • Understanding front-end versus back-end classes
  • Basic techniques for working with the Domino Object Model
  • Using script libraries
  • Domino Object Model LotusScript classes
  • Front-end classes
  • Back-end classes

Chapter 32 — Java and Domino Designer
by Brian Benz

Java has come a long way since a group called the “green team” was locked away in the Menlo Park, CA offices of Sun in 1991 to make an interactive TV system. The system was ahead of its time and didn’t sell well, but it spawned processor-independent technology to send and display interactive features on a screen. Interestingly for Domino developers, the interactive features and functionality were originally described as agents. The next objects to use Java were applets, which were small applications that could be delivered and displayed on a screen via the Internet. This technology took off in 1994 when Netscape announced a Java Virtual Machine (JVM) as a core component of its new Navigator Browser software. In 1997, Lotus added Java to Domino 4.6 and announced that Java would be a core component of the new Domino Designer in R5. At that time, Java had come full-circle, from interactive agents on a custom interactive TV system to interactive agents in Notes clients and on the Web. Today, Java is still used for applet delivery and functionality; however, it is more often used for server-side development and is rapidly becoming the back-end server language of choice when developing high-capacity enterprise Web applications. This chapter provides an overview of Java and the details and capabilities of Java in Domino, including building Domino agents and creating Java code libraries.

Outline:

  • Introducing Java
  • Understanding Java functionality in Domino Designer
  • Using the Domino Designer Java UI
  • Developing an agent in Designer
  • Storing and referencing Java in a Domino code library

Chapter 33 — Java Classes and Methods
by Brian Benz

Download the example files

Domino Java classes and methods are an interface to the same Domino back-end classes that LotusScript uses. Developers will find many similarities between the LotusScript classes and syntax in Part VI (LotusScript) and the Java classes and methods in this part.In this chapter, we convert the LotusScript Newsletter mailing agent example to a single-threaded Java agent by starting with the Hello World Java agent from the last chapter and adding Domino Java classes and methods to correspond to the original agent’s LotusScript classes and methods. We then discuss the advantages of multithreaded Java and show what is required to convert the single-threaded Java agent to a multithreaded agent using the NotesThread class.

Outline:

  • Introducing the Domino Java classes
  • Developing complex Domino agents in Java
  • Java agent development for LotusScript developers
  • Handling multiple classes in a Java agent
  • Developing multithreaded Java agents
  • Passing values from one Java agent thread and class to another

Chapter 34 — Accessing Domino from Java Applications
by Brian Benz

Download the example files

Java applications are stand-alone applications that have been written in Java instead of another programming language, such as C++. This chapter covers the steps necessary to integrate Domino data into a Java application by developing an interactive Java application UI that accesses Domino views, documents, and fields via the same Notes Objects Interface used for agent examples in Chapters 32 and 33.

Outline:

  • Introducing Domino Java applications

  • Learning the prerequisites for developing Domino applications in Java
  • Converting a simple Domino Java agent to a Java application
  • An advanced Domino Java application example

by Brian Benz

Download the example files (Diagnostic Servlet, Newletter Distribution and Java Servlet)

Domino has native capabilities for supporting Java servlets. In this chapter, we discuss that capability, how to code a servlet for use in the Domino environment, and issues surrounding Domino servlet deployment, performance, and security. Illustrating the examples will be the development and deployment of a simple Domino servlet.

Outline:

  • Introduction to servlets
  • Introduction to Domino Java servlets
  • Prerequisites for developing Domino servlets
  • A simple servlet example: Domino diagnostics
  • Converting a Java agent to a servlet

Chapter 36 — Java Servlets Using Third-Party Developer Tools
by Brian Benz

Chapters 34 and 35 reviewed techniques for making Java applications and servlets work with Domino, but an important detail was glossed over — how are Domino Java servlets and applications developed? The Domino Designer UI is a great place to build Java agents, and it can even store and compile some simple applications and servlets. But most Java applications require classes and methods that the Domino Designer UI was never meant to handle. Complex application and servlet Java can usually be loaded into the UI, and the interface can even break up and list the classes in the Work pane to the left of the Programmer’s pane. Unfortunately, saving and compiling are not so predictable. This chapter outlines the steps for enabling Domino object support for the two most popular Java application development environments: WebSphere Studio Workbench, and SunOne Studio. Two options are discussed, partly because most large organizations with J2EE development initiatives have standardized on one of these platforms, and partly because of the different approaches taken in the user interface and features. Both platforms need some customization to enable the compiling and running of Domino applications, applets, and servlets, which we will cover in detail in this chapter. If readers already have one of these environments set up and running and configured for access to Domino objects, they can probably skip this chapter.

Outline:

  • Developing Java applications and servlets
  • Developing Domino servlets with WebSphere Studio Workbench 2.0.1
  • Developing Domino servlets with SunONE Studio 4.0

Chapter 37 — Domino Custom JSP Tags
by Brian Benz

You learn about servlet development using Domino JSP tags, deployment of JSP and Domino access capability on a remote server, and formatting of JSP content. You find out how to add JSP tag capabilities using the example diagnostic servlet from Chapter 35.

  • Outline:
  • Introducing Java Server Pages
  • Introducing JSP tags
  • Working with Domino custom JSP tags
  • Using Domino JSP tags

Chapter 38 — Domino and WebSphere
by Brian Benz

WebSphere application server is a J2EE servlet manager that provides scalability, security, and enterprise data access for servlet-based J2EE Web applications. The standard edition of WebSphere server has been bundled with Domino since early versions of R5, and Domino capabilities for accessing servlet functionality via CORBA are incorporated into Domino server. This chapter discusses the issues involved in deploying a servlet on WebSphere that accesses Domino data, and illustrates the issues and procedures by deploying and configuring J2EE Web applications and JSPs using Domino custom JSP tags on a WebSphere server.

Outline:

  • Understanding the limitations of using WebSphere with Domino
  • Installing WebSphere
  • Configuring the Domino server for WebSphere

Part VIII — JavaScript Techniques.

JavaScript is a great tool for field validation and form data manipulation. Fields can be formatted, date fields can be verified, Numeric fields can be calculated before saving, and text lists and fields can be manipulated and populated based on user input. JavaScript is also very good for Web client image manipulation and navigation. JavaScript can be used to create rollovers and link highlighting, as well as more advanced DHTML techniques. In this part we'll cover JavaScript data entry validation, calculation, image manipulation and DHTML techniques.

Chapter 39 — JavaScript Basics
by Brian Benz

Download the example files

JavaScript is a platform-independent, event-driven, interpreted programming language that has been part of Domino since R5, and could be used with Domino 4.6 versions of Domino via pass-thru HTML. JavaScript should not to be confused with Java, which is very different in terms of functionality and language. JavaScript and Java can communicate with each other because the original intention was that a combination of Java applets and JavaScript would represent a complete client-side Web application development platform. However, for several technical and non-technical reasons, this never came to full fruition. Today, JavaScript is a common extension to HTML that can enhance the user experience by handling client-side events and application control in browser clients. JavaScript is useful for adding interactivity to Domino Web applications and Notes client applications. The Notes 6 client JavaScript feature set has added more complete access to JavaScript classes and methods than prior implementations and eliminated many of the bugs that hampered Notes client JavaScript development in R5. This chapter introduces JavaScript and describes basic techniques for JavaScript document object access and for detecting JavaScript client settings. The next chapter provides more information about the Notes DOM and JavaScript events in Domino.

Outline:

  • Introducing JavaScript
  • Understanding JavaScript structure and syntax
  • Understanding the Domino Designer JavaScript UI

Chapter 42 — Combining Domino and Java Applets using JavaScript
by Brian Benz

Download the example files

JavaScript and Java applets can be connected to each other in Domino using an interface called LiveConnect. LiveConnect is supported in the most recent versions of Navigator, MS IE, and the Notes client, and manipulates Java applets using JavaScript through the applet API without the need for Java. However, the Java applet API must be available or published somewhere to have this work. Domino objects are available to Java applets using the Java AppletBase class. Domino has created four applets based on this class that can be embedded into Notes applications; the Outline, View, and Action Bar and Editor (Rich Text) applets. Other applets that extend the AppletBase class can also be accessed using LiveConnect, if the Applet APIs are published. This chapter provides some examples of manipulating Java applets from JavaScript using the Domino Designer UI, including isolating Java applet calls, properties, and methods, and using those calls to change properties of an applet embedded in an HTML page. It also covers techniques for embedding the JavaScript to Java calls into existing Domino UI elements.

Outline:

  • Using Java applets
  • Using JavaScript and Java applets
  • Embedding applets in HTML pages
  • Working with Domino Java applets in Domino forms
  • Understanding Domino applets

This chapter covers tips and techniques for building data integration into Domino applications. After you review the options for data integration, you learn several techniques for including enterprise data in Domino applications by using an application that uses Domino Enterprise Connectivity Services (DECS), ODBC, LotusScript agents, JavaScript, @Functions, and Data Connection Resources (DCRs). You can apply the same techniques discussed for DECS and DCRs to all the data integration options in this chapter.

Outline:

  • Learning Domino data integration options
  • Introducing Domino Enterprise Connectivity Services and Data Connection Resources
  • Understanding a Domino 6 DECS/DCR example
  • Setting up the Domino 6 Bible DECS examples

Chapter 44 — Developing Domino Applications for Data Integration
by Brian Benz

This chapter extends the data integration concepts that you learned in Chapter 43 by illustrating several practical examples of a working data integration solution. The example application uses Domino Enterprise Connectivity Services (DECS) to connect to an access database that contains over 1,000 popular quotations. The quotes table in the database contains four columns: A unique key for each quotation, a quotation source, the quotation, and the date that the quotation was added to the database. The application provides good examples of application, form, and other design element techniques for developing Domino solutions that integrate with enterprise data. The application in this chapter uses Domino Enterprise Connectivity Services (DECS) and Data Connection Resources (DCRs), but you can easily adapt it to use any Domino data integration option using the same techniques.

Outline:

  • Triggering simple queries
  • Triggering multiple queries on a single query form
  • Switching forms to display single or multiple query results
