Alphabet soup: JavaOne spotlights Enterprise Service Bus
By Staff -- Manufacturing Business Technology, 9/1/2005 6:00:00 AM
The emergence of Enterprise Service Bus (ESB) was a highlight at this year's JavaOne conference. On the heels of the Java Community Process' (JCP) formal approval of Java Business Integration (JBI), a standard specifying the functions of an ESB, Sun Microsystems and TIBCOannounced plans to release JBI-compliant products over the next year.
ESBs have risen to prominence with the emergence of services-oriented architectures (SOAs). Taking a lighterweight, highly distributed approach to embedding many of the functions of traditional application servers on the network, ESBs are considered a better match for SOAs. Until now, the Java community has said little officially about ESBs.
Sun announced Open ESB, its JBI-compliant implementation that is being released in beta form as part of its open-source Glassfish project. Sun's initial code includes software development kits for interfaces to Open ESB.
TIBCO announced Project Matrix, its JBI-compliant enterprise bus, with early release set for the first half of 2006. It will include a deployment platform for packaging services, using a JBI-compliant service router as a distributed extension of its Rendezvous publish-and-subscribe integration platform. In the future, TIBCO will add service containers for hosting non-Java services based on Microsoft .NET, C++, or other components.
While JCP's 14 - 2 vote in favor of JBI appeared lopsided, the two abstainers—IBM and BEA—are Java's two largest players. Both stated they preferred the more narrowly defined BPEL (Business Process Execution Language) standard that they cosponsored in the Web services standards body Oasis. While JBI covers ESBs, BPEL restricts itself to specifying how complex business services are orchestrated.
