spring-ws: no endpoint mapping found

The EndpointNotFoundException occurs when Spring-WS cannot find a suitable @Endpoint that can handle the incoming request.

In this case, the incoming message has namespace http://www.servesy.com/api/v1/service and local name signupRequest (as can be seen in the log). While your @PayloadRoot mapping does have the same namespace; it does not have the same local name, as it uses SignupRequest with a capital S. Chances are that if you change the uppercase S to a lower case s in the @PayloadRoot annotation, it will work.
