WSDL files are created for both JCA Outbound (Request-Response service – BPEL invoke) and JCA Inbound (Event Notification – BPEL receive) Interactions and saved to a local directory. These WSDLs are exposed to the BPEL Designer via the WSIL servlet. The Jdeveloper based design-time wizard has a WSIF browser that is launched from the BPEL Partner Link activity to explore the WSDLs generated by the Oracle AS Adapter Application Explorer. To start Oracle AS Adapter Application Explorer 1. Open a command prompt and cd to adapters/application directory. Run “iaexplorer.exe”. 2. Create a JCA project and point it to the Adapters home directory as shown below. 3. Select the jca project, right-click and select “connect”. Expand the Adapters and Event icons. 4.
