Adding a Partner Link for an Asynchronous Service

These instructions describe how to create a partner link in a BPEL process (for this example, named LoanService) for the loan application approver web service.

To add a partner link for an asynchronous service:

  1. In the SOA Composite Editor, drag a BPEL process from the Components section of the Components window into the designer.

    The Create BPEL Process dialog appears.

  2. Follow the instructions in the dialog to create an asynchronous BPEL process service component.
  3. Click OK when complete.
  4. In the SOA composite application in the SOA Composite Editor, double-click the BPEL process service component (for this example, the component is named LoanBroker).

    Oracle BPEL Designer appears.

  5. In the Components window, expand BPEL Constructs.
  6. Drag a Partner Link icon into the right Partner Links swimlane.

    The Create Partner Link dialog appears.

  7. Enter the following details to create a partner link and select the loan application approver web service:

    • Name

      Enter a name for the partner link (for this example, LoanService is entered).

    • Process

      Displays the BPEL process service component name (for this example, LoanBroker appears).

    • WSDL URL

      Enter the name of the Web Services Description Language (WSDL) file to use. Click the SOA Resource Browser icon above this field to locate the correct WSDL.

    • Partner Link Type

      Refers to the external service with which the BPEL process service component is to interface. Select from the list (for this example, LoanService is selected).

    • Partner Role

      Refers to the role of the external source, for example, provider. Select from the list (for this example, LoanServiceProvider is selected).

    • My Role

      Refers to the role of the BPEL process service component in this interaction. Select from the list (for this example, LoanServiceRequester is selected).

  8. Click OK.

    A new partner link for the loan application approver web service (United Loan) appears in the swimlane of the designer.
