Using Derby as a Java EE resource manager

The Java Platform, Enterprise Edition (the Java EE platform) is a standard for development of enterprise applications based on reusable components in a multi-tier environment. In addition to the features of the Java Platform, Standard Edition (the Java SE platform), the Java EE platform adds support for Enterprise JavaBeans (EJB) technology, the Java Persistence API, JavaServer Faces technology, Java Servlet technology, JavaServer Pages (JSP) technology, and many more. The Java EE platform architecture is used to bring together existing technologies and enterprise applications in a single, manageable environment.

Derby is a Java EE platform conformant component in a distributed Java EE system. As such, Derby 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. Within this system, Derby can serve as the resource manager.

Note: This section does not show you how to use Derby as a Resource Manager. Instead, it provides details specific to Derby that are not covered in the specification. This information is useful to programmers developing other modules in a distributed Java EE system, not to end-user application developers.

In order to qualify as a resource manager in a Java EE system, the Java EE platform requires three basic areas of support. These three areas of support involve implementation of APIs and are described in "Java EE Compliance: Java Transaction API and javax.sql Extensions" in the Java DB Reference Manual.

This chapter describes the Derby classes that implement the APIs and provides some implementation-specific details.
