The Oracle Application adapter is available for SAP, Siebel, JD Edwards, and PeopleSoft. The following diagram depicts the architecture of the Application adapter's framework:
Application Explorer: this is a Java Swing-based design-time tool for configuring the packaged application adapters. Application Explorer provides the required features to enlist the application objects from the application and expose them service.
BSE: this is Business Service Engine, which is integrated as part of the Oracle Application adapter that will aid in communicating with the required packaged applications.
SOAP Connections: BSE uses SOAP connections as a protocol for accepting the client request and interacting with packaged applications.
