Sun Microsystems has released key Java enterprise technologies to the open source community.
Code for Java System Application Server Platform Edition 9.0 and the Java System Enterprise Server Bus (ESB) has been turned over to open source under the same licensing conditions as its Solaris operating system.
Based on the latest Java Platform, Java System Application Server Platform Edition 9.0 is designed to deliver greater ease of development and greater support for web services and service oriented architectures (SOAs).
Java ESB increases business agility and reduces the cost of integration through an open integration framework, enabling users to more rapidly implement open SOA applications.
Sun will donate 135,000 lines of collaboration and infrastructure source code from Java System Instant Messaging and Java Studio Enterprise to the open source community via NetBeans.org.
* Sun is winding down a strategy to sell its Linux-based Java Desktop System (JDS), launched three years ago to compete with Microsoft's Windows products. JDS has won little support on the desktop and Linux remains more popular for servers.
