During JavaOne, devs will get a much better look at how an ESB (Enterprise Service Bus) might boost their careers. Dave Chappell, one of Java's foremost experts on JMS and integration, in his latest book spells out why ESBs will transform how Java devs think about APIs, data sharing and workflow.

"One-hundred-percent portability is getting more difficult to achieve, as Java is fragmenting already," Chappell, Chief Technology Evangelist at Sonic Software, told Integration Developer News. "And while there is still a core set of [Java standards] that depend on the JCP, engineers can become more marketable if they can understand how Java can work in a cross-platform, service-oriented integration environment."

The solution, Chappell says, is the Enterprise Service Bus.
