|Admin Web Application No Longer Budndled w/ Tomcat 5.5
The admin web application is not bundled along with Tomcat 5.5 anymore to enhance out-of-box security. Instead, users can download the admin application separately as jakarta-tomcat-VERSION-admin.zip/tar.gz.
Tomcat 5.0 continues to bundle the admin application as of date.
|3||39||Errors in Text
In the first paragraph of the "Assigning Port Numbers" section (top of page), there are a few incorrect port assignments. The corrections are below:
POP3 uses port 110, not 25
SMTP uses port 25, not 110
The protocol for port 21 is SSH, not SSL.
|5||61||Nesting example beneath second paragraph
The nesting for the default configuration of Tomcat is incorrect. It should be: Server -Service --Connector --Connector --Engine ---Logger ---Realm ---Host ----Logger
|62||First sentence under "The Server Component"
service.xml should read server.xml
under 'The Server Component' First sentence
|124||Error in Code
Under the welcome-file-list section, the source code reads:
However, it should read:
|184||Change in Path
In the "Adding a Resource Definition to the Application Context Descriptor" section, the path in parenthesis should be:
instead of the current:
|307||Unit wrong for parameter removeAbandonedTimeout
In server.xml, the unit of time in the parameter removeAbandonedTimeout is shown in minutes, it should be seconds.
|308||Error in Step 2
Step 2 (<resource-ref> entry in web.xml)not needed IF:
the JNDI resource is set as global.
Having the resource defined in the <DefaultContext> means that the <resource-ref> is not necessary in the web.xml file.
|15||350||"CREATE TABLE user_roles" does not create dual primary
Code should read: create table user_roles ( user_name varchar(15) not null, role_name varchar(15) not null, primary key (user_name, role_name) );
|13||Chapter 13||Error of Connector
Tomcat's JK2 Connector was deprecated after the book was released. The latest versions of Tomcat recommend using the JK connector. This Connector will be covered in detail in the next edition of this book ("Professional Apache Tomcat 6").
