Quickest solution for now is to doubleclick the wsdl > open tab: "Service Endpoints" > edit the endpoints you want to change.
Personally I prefer to have as service-endpoint ${#Project#servicename}, which refers to the custom project property servicename.
This allows me to :
1. (easily) change endpoints at a central spot
2. save the properties to a settings.properties, in order to:
2,1 Easily switch between environments.
2.2 Set properties (like endpoint properties and jdbc connection strings) from the commandline (automatic builds).
