I am trying to build a java ee webservice that has a common base class, but the child classes are the actual @webservice classes (and expose the parent class methods as @webmethod's)

Like this:

public abstract class Parent {
 @WebMethod
 public void doSomething(){//...does stuff}
}

@WebService
public class Child extends Parent {}

I've tried (and have failed):
- annotating the parent class as a webservice as well
- making sure all parent methods are annotated with @WebMethod

Is this possible, if so, how?
