This image shows the following main elements: Application Explorer (design time), Oracle Application Server, EJB or Servlet Container, JCA container containing OracleAS Adapter JCA and the adapter, and an Oracle RDBMS. To the right of the illustration is an element, indicating SAP. The central elements are superimposed upon each other in the following order to indicate where each is deployed: the adapters reside in the adapter framework, which is in the JCA connector, which is in the JCA container, which itself is on top of the Oracle Application Server.

Application Explorer appears separately to the left of the Oracle Application Server. A bidirectional arrow between Application Explorer and the EJB or servlet container indicates the bidirectional connection between the two. On the right side of the illustration, a bidirectional arrow between the adapter and the SAP icon indicate that the adapter connects to SAP to complete service requests, receive responses from SAP, and then communicate that response through the framework and JCA back to Application Explorer.
