Sun Microsystems has announced it is furthering its commitment to open source by delivering a completely open SOA platform with the release of key Java technologies. Sun planned open source contributions include the award-winning Sun Java Studio Creator, market-leading Sun Java System Portal Server, the Business Process Execution Language (BPEL) Engine from the Sun Java Composite Application Platform Suite (Java CAPS) and the NetBeans Enterprise Pack, as well as Sun's Java Message System (JMS)-based message queue and Web Services Interoperability Technology (WSIT).

"This announcement represents the next phase of open sourcing Sun's Java software portfolio," said Rich Green, executive vice president, Software at Sun. "What was started last year with the enterprise Java platform, has now become a complete solution for SOA development through this release of technologies like portal server, the BPEL engine and our development tools."

Sun is releasing the next set of components from the Java Enterprise System as part of its ongoing strategy to open source its entire middleware software stack. Sun is also announcing plans to release its award-winning Sun Java Studio Development Tools as part of the NetBeans.org community.

Building on the momentum from the release of Java Platform Enterprise Edition (Java EE) and the Java System Application Server Enterprise Edition, Sun is expanding Project Glassfish into the OpenJava EE Community to support the development and evolution of Java technology by including additional Java platform components.
