WSDL files are stored in project files. For older projects, you must update Web Service Proxy classes to store WSDL documents.
               This is done by updating individual Web Service Proxy classes with a new WSDL file.

                  		  Select a Web Service Proxy class in the 
                     			 Loaded Components menu tree. 
                     		   
                  		   A property called 
                  			 WSDL is displayed in the 
                  			 Input Data Properties field.

                  		  Select the 
                     			 WSDL parameter and click browse 
                     			 (...). 
                     		   
                  		    The 
                  			 WSDL View dialog box opens, which includes the original URL, the date the WSDL file was downloaded, and the contents of the WSDL file.
                  
                  		   
                  		
               
-  
                  		  Enter a URL in the 
                     			 Compare With text box and click 
                     			 Compare. 
                     		   
                  		   The content check functionality compares the string contents of both files. 
                  		   
                  		
               
You are informed whether or not there is a difference between the files’ contents, but not what the specific difference is.
