Hi Rulin,
The J2EE Connector architecture enables J2EE components such as enterprise beans to interact with enterprise information systems (EISs). EIS software includes various types of systems: enterprise resource planning (ERP), mainframe transaction processing, and non-relational databases, among others. The J2EE Connector architecture simplifies the integration of diverse EISs. Each EIS requires just one implementation of the J2EE Connector architecture. Because an implementation adheres to the J2EE Connector Specification, it is portable across all compliant J2EE servers.

Ram,
Thanks. That is great explanation. This means that the J2EE Connector architecture may not be used for legacy system integration ? say another web-application, or so.

Nope, JCA concentrates on providing an API for accessing the Enterprise Information Systems. Until now, they have been developing proprietary drivers for accessing EIS and now this API standardizes the process.
 
It is sorta covered in the JavaRanch Style Guide.
