A J2EE Connector Architecture (JCA) resource adapter is any resource adapter conforming to the JCA Specification.
The product supports any resource adapter that implements version 1.0 or 1.5 of this specification. IBM supplies resource adapters for many enterprise systems separately from the WebSphere Application Server package, including (but not limited to): the Customer Information Control System (CICS), Host On-Demand (HOD), Information Management System (IMS), and Systems, Applications, and Products (SAP) R/3 .
The general approach to writing an application that uses a JCA resource adapter is to develop EJB session beans or services with tools such as Rational Application Developer. The session bean uses the javax.resource.cci interfaces to communicate with an enterprise information system through the resource adapter.
