Sanjay Patil standards architect at SAP AG makes a case for SCA and the Java EE 6 standard.
“I certainly think it should,” Patil answered. “The main reason is SCA is really about assembling applications in a technology neutral way. If it was about a specific platform, such as Java EE, you could say there are enough APIs and libraries for Java applications. But if you look at the key value of SCA it’s about recognizing the fact that customers have different technologies, Java EE, BPEL, BPM systems, traditional EAI systems. They have a variety of communications mechanisms including Web services, JMS, and EDI.”
