Re: Ugly Copy/Paste code in WSDL. Where is the Re-use?

[Bill Keese]

I also feel like the WSDL contains a lot of duplicated code, but I don't 
know how to avoid it.  The message definitions (in document/literal 
mode) are also pretty useless, since each message just points to a 
single element (with the same name).

I've thought about generating the WSDL from a simpler XML file, via XSLT.

Greetings,
I have a WSDL document that describes the services of my client. I am 
no expert at web services so I have a question that might be seen as a 
little silly so please excuse me.

In the document I have SEVERAL places where I have the same string 
over and over again. A prime example is my namespace line which 
appears all over the place. In addition, in the bindings section of my 
service, I have 30 operations with the bindings that all look identical:

How can I possibly re-use code to prevent this issue? It would be a 
nightmare of maintenance and so on.

My bindings look like ...
       <wsdl:operation name="fetchNewIssues">
           <wsdlsoap:operation soapAction=""/>
           <wsdl:input name="fetchNewIssuesRequest">
               <wsdlsoap:body 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:input>
           <wsdl:output name="fetchNewIssuesResponse">
               <wsdlsoap:body 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:output>
           <wsdl:fault name="CandiedServicesException">
               <wsdlsoap:fault 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                   name="CandiedServicesException"
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:fault>
       </wsdl:operation>
       <wsdl:operation name="fetchSubscriptionStatuses">
           <wsdlsoap:operation soapAction=""/>
           <wsdl:input name="fetchSubscriptionStatusesRequest">
               <wsdlsoap:body 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:input>
           <wsdl:output name="fetchSubscriptionStatusesResponse">
               <wsdlsoap:body 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:output>
           <wsdl:fault name="CandiedServicesException">
               <wsdlsoap:fault 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
                   name="CandiedServicesException"
                  
namespace="urn:com.bmw.candy.CandiedServices.SubscriptionAccess" 
use="encoded"/>
           </wsdl:fault>
       </wsdl:operation>

And so on ... you can see that each entry is practically identical 
except the name of the request and response.

Thanks in advance.
