Sun announced beta versions of these technologies on Feb. 21, saying these offerings feature technologies that provide developers with the next-generation Java platform and tools for building and deploying Web services and SOA (service-oriented architecture) applications.
Moreover, the new betas feature contributions from the open-source GlassFish Project and NetBeans communities, the company said.
And the news comes on the heels of several recent developer-oriented announcements Sun has made, including the launches of NetBeans 5.0, Java Studio Creator 2, Java Standard Edition 6 (aka Project Mustang), Java Studio Enterprise 8, and Sun Studio 11—all of which are also now available at no cost to developers, the company said.
