Purpose

Your applications can connect to J2EE Connector Architecture (JCA)-compliant resource adapters that support the Common Client Interface (CCI) of the JCA specification.

JCA implements a mechanism for accessing legacy systems — called back-end enterprise information systems (EIS) — from Java or J2EE applications. A JCA resource adapter plugs into the J2EE application server and connects applications to a specific EIS. A JCA resource adapter data instance defines the properties of a single resource adapter that is deployed in the same application server that hosts Process Commander.

You can deploy the JCA resource adapter in either a managed environment (deployed in a J2EE application server) or a non-managed environment (deployed in a non-J2EE Web application server).

Before you begin

Before creating a resource adapter data instance, verify that the resource adapter is deployed:

If your Process Commander system operates in a managed environment, the resource adapter .rar file must be deployed in the same J2EE application server.
If your system operates in a non-managed environment, place the resource adapter .jar file an appropriate directory and update the compiler class paths. See the Pega Developer Network article PRKB-20931 About the Process Commander class paths.

Referenced by

A JCA connector rule uses the information in a JCA resource adapter instance when connecting to a resource adapter to send a request to an Enterprise Information System at runtime. See About Connect JCA Rules.
