Follow these steps to set up a TCP listener to display the SOAP messages for callbacks from asynchronous services:

1. Start a TCP listener to listen on a port and send the Oracle BPEL Process Manager port.

   1. Open Oracle Enterprise Manager Fusion Middleware Control.

   2. From the SOA Infrastructure menu, select SOA Administration > Common Properties.

   3. Specify the value for Callback Server URL. This URL is sent by the server as part of the asynchronous callback address to the invoker.

2. From the SOA Infrastructure menu, select Administration > System MBean Browser.

3. Expand Application Defined MBeans > oracle.soa.config > Server : soa_server > SCAComposite.

   where soa_server is the specific server instance name (for example, AdminServer).

   All the SOA composite applications deployed on the server appear.

4. Follow these steps to set this property on a composite application. This action enables it to apply to all bindings in the composite application.

   1. Click your composite.

   2. Ensure the Attributes tab is selected.

   3. In the Name column, click Properties.

   4. Click the Add icon.

   5. Expand the newly added Element_number (appears at the end of the list).

      where number is the next sequential number beyond the last property. For example, if the property list contains twelve elements, adding a new property causes Element_13 to be displayed.

   6. In the name field, enter oracle.webservices.local.optimization.

   7. In the value field, enter false.

   8. In the many field, enter false.

   9. Click Apply, and then click Return.

   10. In the Name column on the Operations tab, click save.

   11. Click Invoke to execute the operation.

   12. Click Return or click a node in the System MBean Browser pane.

       Note:

       After adding, deleting, or updating a property, you can click the Refresh cached tree data icon in the upper right corner of the System MBean Browser page to see the new data.

5. Follow these steps to set this property on a specific binding.

   1. Expand your composite application. and navigate to the specific SCAComposite.SCAReference.SCABinding folder.

   2. Click WSBinding.

   3. Perform steps 44.b through 44.l.

6. Initiate any flow that invokes asynchronous web services. You can combine this with the synchronous TCP tunneling configuration to send a service initiation request through your first TCP tunnel.

   The callbacks from the asynchronous services are shown in the TCP listener.

If you are an Oracle JDeveloper user, you can also use the built-in Packet Monitor to see SOAP messages for both synchronous and asynchronous services.
