Another tool that you might use to test and debug a Web service client is a SOAP viewer. You can configure a SOAP viewer to intercept all messages sent between the Web service client and the WSA instance. You can then view and possibly modify them (depending on the viewer) before you allow them to continue to their destination. Depending on the viewer, you might have to alter the Web service URL in the client to accommodate the viewer. OpenEdge provides SOAP viewing tools with the installation, but they are also widely available. For more information on testing and debugging Web services and Web service clients, see OpenEdge Development: Web Services.
