Java EE Connector Architecture (JCA)

Java EE Connector Architecture (JCA) defines a standard architecture for JEE systems to access external heterogenous Enterprise Information Systems (EIS), such as databases, messaging systems and mainframe transaction processing.

Resource Adapter

A resource adapter is a component that implements JCA API and architecture. It is similar to a datasource, however, it provides connectivity to and from an Enterprise Information System (EIS) such as a database, messaging system, transaction processing system, etc. From an Application Server's perspective, a resource adapter is a deployable component, packaged in a Resource Adapter Archive (RAR), whose file can be deployed within the AS.
