When you add a web service to the IDE, the web service is defined in a Web Service Definition Language (WSDL) file. The WSDL file describes how to access the web service and what actions the web service will perform. You can view a read-only version of the WSDL file that was used to create each web service added to the IDE.
If necessary, expand the node for the web service group.
Right-click a web service and choose View WSDL.
If you have trouble viewing the WSDL file, make sure that your network connection to
the WSDL is functioning properly and that the address of the WSDL file has not changed since the
WSDL was added to the IDE.
