Java ORBs, both commercial and open source, are today ubiquitously available. Java development environments which comply to the JDK1.2 (or higher) specification provide also basic CORBA support. Many vendors, too many to list them, offer products which provide Java ORBs directly or embedded into some higher-level environment such as integrated development environments or application servers. The OMG publishes a buyers guide which lists many CORBA implementations and CORBA enabled products.

Rather than creating yet another list of links to Java ORBs, we refer you to the pages maintained by Christof Meerwald, by Ben Eng, by Doug Schmidt, by Wolfgang Lugmayer, by Junichi Suzuki, and by Tom Valesky, which list CORBA implementations, availability of language bindings and services, and lots of other useful information about CORBA.

The ORBs that we used for the examples in the book are Visibroker for Java 4.1 and JacORB 1.2. A trial version of Visibroker for Java can be down-loaded from the Inprise Web site. Visibroker for Java is also integrated in development tools, for example in Borland's JBuilder - Client/Server. JacORB is an open source implementation and freely available from the JacORB Web site.
