Re-wiring an SOA composite application

Now we will re-wire the TravelApproval composite application to remove the direct connection to the service and replace it with the connection to the proxy service. We open our TravelApproval SOA composite application in JDeveloper again, and double-click the composite.xml to open the SOA Composite Editor. We will modify the EmployeeTravelStatus reference binding component, as we want to remove the direct connection to the service. Instead, we will use the proxy service we just created. We will find the Proxy service by browsing the Oracle Service Registry, therefore, we have to create a connection to the OSR on the Resource Palette first. To ensure even greater flexibility, we will enable dynamic endpoint lookup, so that the actual address of the proxy service will be retrieved from the OSR at runtime.

We double-click the EmployeeTravelStatus reference binding component. Then we click on the Find existing WSDLs icon next to the WSDL URL input field...
