Executive Summary

For a long time, J2EE seemed a powerful, complex technology. Now Java EE 5 keeps the power of the old J2EE, but the new version is much simpler and easier to use than the preceding ones. This article explores some of the new Java EE 5 features. In Java EE 5, the JSP and JSF standards are better integrated through the unified expression language, which means any custom JSP tags, including tag files, can now use deferred values and methods in their attributes. With explicit diagrams this paper shows how Oracle's Java EE 5 works through. It is like a workshop that helps the user to use the applications with ease. The Oracle Workshop lets the user build and configure the application faster with the help of specialized wizards, editors, component palettes, and property sheets. In addition, the AppXRay technology of Oracle Workshop allows one to navigate quickly through the files and provides code completion and validation features that minimize the need to consult the documentation and significantly reduce the development and testing time. Java EE's annotations are a good replacement for the XML-based EJB deployment descriptors for fewer files to edit when making changes. EJB's persistence is based on Plain Old Java Object (POJO) model. Annotations can be used in any Java-based components, including EJBs, Servlets, and JSF managed beans.
