Offline stand-alone WSDL generation from WCF for Java client

I'm looking to generate a WSDL for offline use that someone can then use to create a service reference and generate a mock service to test their client against. Simple, right? Just use svcutil to generate the files:

svcutil http://localhost:1234/MyService.svc /t:metadata

The developer of the client can then use soapUI to generate a mock service.

The trouble is the files contain references to http://localhost:1234/MyService.svc, so soapUI fails when trying to create the mock service with the error:

Error loading [http://localhost:1234/MyService?wsdl=wsdl1]:
java.lang.Exception: Failed to load url;
http://localhost:1234/MyService.svc?wsdl=wsdl1, 0 -

• I can't use wsdl.exe, as the client is in Java, so C# files are of no use.
• I've tried Disco.exe, but same result.
• The client developer cannot add a service reference in Visual Studio as they do not have Visual Studio.

I've found a reference to download WSDL files for offline use, but surely there must be some easier way of generating a complete self-contained offline WSDL without installing Java or requiring a live service?
