At its JavaOne developer conference this week Sun Microsystems has announced it is making key Java Enterprise technologies open source.
Code for the Java Application Server version 9.0 and the Java Enterprise Server Bus has been released to the open source community, under the same licensing conditions as Sun's Solaris operating system.
Java Application Server 9.0 is the benchmark for compatibility in Java Enterprise environments.
Based on the latest Java Enterprise Edition 5 reference implementation, Java Application Server 9.0 aims to deliver greater ease of development, and more support for web services and service-oriented architectures (SOAs).
Sun said Java Enterprise Server Bus increased business agility and reduced cost of integration through an open integration framework for SOAs, enabling users to implement open SOA applications more rapidly.
In addition, Sun is donating 135,000 lines of collaboration and infrastructure source code from its Java Instant Messaging and Java Studio Enterprise products to the open source community via NetBeans.org.
