A number of Java EE 6-related JSRs (Java Specification Requests) have been finalized over the past few months, and the final round of voting ended on November 30 and all were approved. Today, December 10, 2009, the reference implementations of Java EE 6, Java EE 6 and GlassFish v3, were released.
Four and a half years after the release of Java EE 5, we have entered the next era of Java EE. GlassFish v3 is the first application server to fully support all Java EE 6 technologies. Supported technologies include but are not limited to the following technologies:
Servlet 3.0
JSF 2.0
WebBeans
CDI (Contexts and Dependency Injection)
Bean Validation
EJB 3.1
JPA 2.0
JAX-RS
GlassFish v3 can be downloaded in two ways: the first includes all Java EE 6 technologies, and the second includes all technologies in the Java EE 6 Web Profile standard.
It is worth mentioning that Java EE is more powerful than before. Now we can use annotations instead of XML configuration, we can not use EAR files because WAR is enough, Ajax has been standardized, and asynchronous calls are supported from the client and even to the database.
