Object documentation Resource Adapter Archive (RAR)  Locate the document in its SAP Library structure

Definition

An archive file that is defined in the J2EE Connector Architecture specification as the valid format for deployment of resource adapters on application servers.

Use

On the J2EE Engine you can deploy an RAR file as a standalone component. In this case, the resource adapter is accessible for any application by a lookup procedure.

You can also deploy the resource adapter as part of a larger application. In this case you must include the RAR file in the application archive file (EAR). After the deployment, the resource adapter is directly accessible from the application it is a part of. For more information, see Using Resource Adapter to Obtain Connection.

Structure

The RAR file contains:

·        A JAR file with the implementation classes of the resource adapter

·        A META-INF/ directory that stores the ra.xml and the additional connector-j2ee-engine.xml.

Note

The additional deployment descriptor is not required by the J2EE Connector Architecture specification. It is used for configuration purposes in the J2EE Engine. The format of the XML file is defined by the connector-j2ee-engine.dtd.
