SCA Java EE Integration Spec brings the Java world closer to SCA
The SCA Java EE Integration Specification has been released. It is quite an interesting read. The vision of SCA is to build composites and composite applications out of configurable, reusable service components or assets as I had tried to explain earlier. It does not intend to replace existing open standards but to build over those standards to enable a technology agnostic service component integration platform. So it has support for multiple communication protocols (or binding types), component implementation languages (implementation types) and component interface languages (interface types). The list of these types is growing. Also I had mentioned (SCDL vs WSDL) the promise to support so many technologies in a standard manner is indeed a big one!
