Q : How do I show my own WSDL when someone types '?wsdl' on my service?

A : First you need to have a service element in the WSDL file equal to the actual service name, for example, if your service name is myService, then the WSDL file should have the following service element

<definitions >
  .........................
  <service name="myService">
  </service>
</definitions>

Then you have to put the WSDL file into META-INF directory in the service archive file (if you have xsd files you can have them under same location).
