Java Connector Architecture (JCA)
JCA is a general architecture in the Java Enterprise Edition (JEE) environment used to connect heterogeneous systems, such as legacy applications, using a standardized interface in the form of a resource adapter. Agreements (contracts) laid down in the JCA specification guarantee collaboration with other system components (JCASpec 2003).
Uses
Java Connector Architecture (JCA) defines standards for connecting the Java Enterprise Edition platform with heterogeneous, distributed Enterprise Information Systems (EIS). JCA enables EIS to be integrated with application servers and business applications as a result of its developer API and manufacturer API specifications. This guarantees that resource adapters are reusable. The manufacturer of a business application can be certain that the application will communicate in a uniform way with a different EIS. In the same way, the manufacturer of an EIS, which is supplied with a JCA adapter can be sure that the EIS...
