Java Platform, Enterprise Edition 5 (Java EE 5) Overview

Java Platform, Enterprise Edition 5 (Java EE 5) focuses on making development easier, yet retains the richness of the J2EE 1.4 platform. Offering new and updated features such as Enterprise JavaBeans (EJB) Technology 3.0, JavaServer Faces (JSF) Technology, and the latest web services APIs, Java EE 5 makes coding simpler and more straightforward, but maintains the power that has established Java EE as the premier platform for web services and enterprise application development.

The Java EE 5 SDK and Java Application Platform SDK provide support for Java EE 5 specifications, and the Java Application Platform SDK features additional runtimes such as Open ESB, Portlet Container, and Sun Java System Access Manager.
