EJBs and Resource Adapters

An EJB running a COBOL service runs in two places: the COBOL service runs under an enterprise server, and the EJB and client run under a third party J2EE application server, such as WebSphere or WebLogic.

Resource adapters enable EJBs deployed on J2EE to communicate with COBOL on an enterprise server. Resource adapters are also known loosely as J2EE connectors
