Sun Java System Application Server Platform Edition 8.2 Upgrade and Migration Guide

J2EE Component Standards

Application Server 8.2 (hereafter called Application Server) is a J2EE v1.4-compliant server based on the component standards developed by the Java community. By contrast, the Application Server 7 is a J2EE v1.3-compliant server and Application Server 6.x is a J2EE v1.2-compliant server. Between the three J2EE versions, there are considerable differences with the J2EE application component APIs.

The following table characterizes the differences between the component APIs used with the J2EE v1.4-compliant Application Server 8.2, the J2EE v1.3-compliant Application Server 7, and the J2EE v1.2-compliant Application Server 6.x.
