The Official Site for Breaking News and the Latest Information from Sun On The Record

Today, Sun is announcing a new version of Java Enterprise System - Release 6

As you probably know, Java Enterprise System, or Java ES for short, is Sun's comprehensive set of subscription-based services that combines software, support, professional services and educational services in a single package - for a single price, which is based on employee count.

Java ES R6 is comprised of several Java System Suites:

    * Sun Java Enterprise System Base
    * Sun GlassFish Portfolio
    * Sun Java Composite Application Platform Suite (Java CAPS)
    * Sun Java Identity Management Suite
    * Sun Java Availability Suite

This allows customers to purchase Java ES components based on their business requirements. And then, as business needs change, they can easily add additional Suites.

Java ES R6 includes several new software compontents -  Sun GlassFish Web Space Server and Sun OpenSSO Enterprise, as well as GlassFish Portfolio, an open web and application platform. In addition, the Java ES Base suite is now tested with the Identity Management and Java CAPS suites.

There's a great post over on Paul Hinz's blog that gives an overview of Java ES R6. Paul's also got a chart that outlines the particular versions of each of the software components included in Java ES R6 - compared to Java ES R5.

What's particularly helpful about Java ES is that all the software components are rigorously tested to ensure interoperability and reliability. So that way, you know which version of GlassFish Enterprise Server works with NetBeans and OpenSSO Enterprise and Directory Server Enterprise Edition and so on...
