The GlassFish enhancements include support for the SailFin Application Server, another Sun project for telephony via Session Initiation Protocol (SIP) functionality. Next to fixing around 500 bugs, the release adds languages for localization.
GlassFish also implemented and reworked a few components, such as the Shoal Group Management Service (GMS), Open Message Queue (Open MQ) and Session Replication.
The platforms on which GlassFish was tested now include Windows 2008, Open Solaris and Red Hat Enterprise Linux 5. Downloads and installation instructions are available here.
Java Caps 6, the Composite Application Platform Suite, is based on Open ESB and has the latest versions of the Glassfish Server and the Netbeans integrated developer environment on board.
The Java server includes Netbeans and is released under a dual license: Sun CDDL v1.0 and GPL v2.
