This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
JCAPS stands for Java Composite Application Platform Suite. It's not an application server, but a set of tools covering several development targets. Some of the domains that are covered include data transformation (eGate), business process management (eInsight), B2B transaction management (eXchange Integrator), and so on.
Previous releases of these tools have been around for some time under different names. Sun Microsystems bought the founding company (SeeBeyond Technology) a while back and has since been re-packaging many of these tools to use well-known standards (J2EE, Web Services, etc.) and message protocols (HIPAA, EDIFACT, ebXML, etc).
The software release happens to include an Integration Server, which in the current releases is a modified Sun Java Application Server, Platform edition component. The toolset also includes a design tool (based on NetBeans) and a management server with a browser-based interface.
