Sun is putting the latest Java platform onto Ubuntu Linux.

Java Enterprise Edition 5 (JEE5) is the first Java application server to be distributed via Ubuntu, according to Jane Silber, chief operating officer for Canonical, the non-profit sponsor of Ubuntu Linux.

JEE is a programming platform to develop and run distributed Java applications on modular software components running on an application server, and JEE5 has been developed by the Sun-sponsored GlassFish, an open-source software development group focused on enterprise-level applications, including documentation, administration, monitoring and support.

The GlassFish-Ubuntu combination give developers access to the open-source frameworks needed to develop the next generation of Web 2.0 applications and Ubuntu access to more Java servers, Silber said. "It helps us and the Ubuntu development community in terms of making GlassFish available and deploying enterprise systems and applications," Silber said.

Sun will also announce that Canonical will certify and support Ubuntu on Sun's x64 family of servers, based on AMD's Opteron. Ubuntu already is certified to run on servers and workstations based on Sun's UltraSparc processors.
