The Oracle JCA adapters are deployed as JCA 1.5 resource adapters in an Oracle WebLogic Server container. Adapters are packaged as Resource Adapter Archive (RAR) files using a JAR format. When adapters are deployed, the RAR files are used and the adapters are registered as connectors with the Oracle WebLogic Server or middle-tier platform. The RAR file contains the following:

• The ra.xml file, which is the deployment descriptor XML file containing deployment-specific information about the resource adapter

• Declarative information about the contract between Oracle WebLogic Server and the resource adapter

Adapters also package the weblogic-ra.xml template file, which defines the endpoints for connection factories.
