7 Using Cloudscape as a J2EE Resource Manager
J2EE, or the Java 2 Platform, Enterprise Edition, is a new standard for development of enterprise applications; one example is Enterprise Java Beans (EJBs) with distributed capabilities.
Cloudscape Version 3.6 is a J2EE-conformant component in a distributed J2EE system. As such, it is one part of a larger system that includes, among other things, a JNDI server, a connection pool module, a transaction manager, a resource manager, and user applications. Cloudscape also supports the JTA API, which is not a current J2EE requirement, but this functionality provides another piece of the same system. Within this system, Cloudscape can serve as the resource manager.
For more information on J2EE and how to work in this environment, see the J2EE specification available at http://java.sun.com/j2ee/docs.html.
NOTE: This chapter does not show you how to use Cloudscape as a Resource Manager. Instead, it provides details specific to Cloudscape that are not covered in the specification. This information is useful to programmers developing other modules in a distributed J2EE system, not to end-user application developers.
In order to qualify as a resource manager in a J2EE system, J2EE requires these basic areas of support. These three areas of support involve implementation of APIS and are described in Chapter 8, "J2EE Compliance: Java Transaction API and javax.sql Extensions" in the Cloudscape Reference Manual.
This chapter describes the Cloudscape classes that implement the APIs and provides some implementation-specific details.
NOTE: All of the classes described in this chapter require a JDK 1.2 environment.
