A resource adapter is a system library specific to an Enterprise Information System (EIS) and provides connectivity to an EIS. A resource adapter is analogous to a JDBC driver, which provides connectivity to a database management system. The interface between a resource adapter and the EIS is specific to the underlying EIS. The resource adapter plugs into an application server, such as WebLogic Server, and provides seamless connectivity between the EIS, application server, and enterprise application.
WebLogic Server supports resource adapters developed under the Java EE 1.0, 1.5, and 1.7 Connector Architectures. For information about developing resource adapters, see Developing Resource Adapters for Oracle WebLogic Server.
A resource adapter is packaged and deployed like any other
application. Its initial configuration can be specified in its
deployment descriptor files,
weblogic-ra.xml. You can configure the following
aspects of a resource adapter using the Administration Console:
