How To Create a Dynamic Partner Link at Design Time for Use at Runtime

Create a WSDL file that contains multiple services that use the same portType.

<service name="AmericanLoan">
 <port name="LoanServicePort" binding="tns:LoanServiceBinding">
  <soap:address location="host:port/soa-infra/services/domain_
name/AmericanLoan/client"/>
 </port>
</service>

<service name="AlliedLoan">
 <port name="LoanServicePort" binding="tns:LoanServiceBinding">
  <soap:address location="host:port/soa-infra/services/domain_
name/AlliedLoan/client"/>
 </port>
</service>

<service name="AcmeLoan">
 <port name="LoanServicePort" binding="tns:LoanServiceBinding">
  <soap:address location="host:port/soa-infra/services/domain_
name/AcmeLoan/client"/>
 </port>
</service>

Drag a SOAP binding component into the External References swim lane of the SOA Composite Editor.

The Create Web Service dialog appears.

Define the web service, and click OK.

When complete, the reference binding component entry in the composite.xml file that uses the WSDL looks as follows:

<reference name="loanService">
  <interface.wsdl interface="http://services.otn.com#wsdl.interface(LoanService)"
callbackInterface="http://services.otn.com#wsdl.interface(LoanServiceCallback)"
/>
    <binding.ws port=
       "http://services.otn.com#wsdl.endpoint(AmericanLoan/LoanService_pt)"/>
  </reference>

Note:

Adding the binding.ws port setting is optional. This is because the port is overridden at runtime by properties passed from Oracle BPEL Process Manager.
If there is no port setting, and there is no composite import of the concrete WSDL associated with this reference, you must specify the location of the concrete WSDL with a location attribute.

Double-click the BPEL process to enter Oracle BPEL Designer.

Drag an Assign activity into the designer.

Above the target partner link, select the XML Fragment icon, as shown in Figure 8-3. If you are using BPEL 2.0, drag the Literal icon.

Drag the icon to the target partner link.

The XML Fragment dialog for BPEL 1.1 appears. If you are using BPEL 2.0, the Literal dialog appears.

Assign an XML fragment containing the endpoint reference to the partner link, and click OK. Figure 8-4 provides details.

When complete, the BPEL file contains one of the services defined in the WSDL.

The following provides a BPEL 1.1 sample:

<EndpointReference xmlns="http://schemas.xmlsoap.org/ws/2003/03/addressing">
         <Address>http://host:port/soa-infra/services/domain_name
           /AlliedLoan/client</Address>
<ServiceName xmlns:ns1="http://services.otn.com"
   PortName="LoanServicePort">ns1:AlliedLoan</ServiceName>
</EndpointReference>

The following provides a BPEL 2.0 sample:

<assign>
  <copy>
    <from>
      <literal>
        <sref:service-ref>
          <services:EndpointReference>
          <services:Address>http://host:port/soa-infra/services/domain_
           name/AlliedLoan/client</services:Address>
           <services:ServiceName
           xmlns:ns1="http://services.otn.com">ns1:AlliedLoan</services:
           ServiceName>
          </services:EndpointReference>
        </sref:service-ref>
      </literal>
    </from>
    <to partnerLink="LoanService"/>
  </copy>
</assign>
