Invoking a service from a BPEL process

BPEL uses Partner Link for invoking synchronous and asynchronous services. BPEL processes may alternatively use the Invoke activity that opens a port in the BPEL service component to send and receive data.

Partner Link

Partner Link provides references to external services. Partner Link is the door for outside services. While editing a BPEL process, one can create a Partner Link to invoke external services. As shown in the following screenshot, drag-and-drop the Partner Link to the JDeveloper console and select the SOA Resource Browser for selecting the WSDL for interacting with another web service using the standard WSDL interface:

As shown in the following screenshot, select the WSDL file from your filesystem for interacting with another web service. Other options are to locate the WSDL file from Resource Palette and Application or retrieve WSDL using the WSDL endpoint URL. It is recommended to test and confirm the WSDL URL using an external web browser...
