I continue to search your site for these acronyms… and see nothing.
I simply can’t believe that an outfit supposedly devoted to Enterprise development could continue to ignore Enterprise Service Bus (ESB), Service Oriented Architecture (SOA) and Businees Process Execution Language (BPEL). If these acronyms are not familiar to you… shame on you.
Both Glassfish/NetBeans and Oracle/JDeveloper have SOA/BPEL built-in. There is a BPEL designer (in the earlier stages of development I think) on the Eclipse web site..
I really encourage you to put integration of these capabilities at the top of your priority list.
