> I have not investigated the code but based on the following stack trace I doubt we are
correctly implementing ewebsvcs-1_1-mr-spec section 5.3.2.2:
> The Service Implementation Bean may implement the Service Endpoint Interface as defined
by the  JAX-RPC Servlet model. The bean must implement all the method signatures of the SEI.
In addition,  a Service Implementation Bean may be implemented that does not implement the
SEI. This  additional requirement provides the same SEI implementation flexibility as provided
by EJB service  endpoints. The business methods of the bean must be public and must not be
static. If the Service  Implementation Bean does not implement the SEI, the business methods
must not be final. The  Service Implementation Bean may implement other methods in addition
to those defined by the SEI,  but only the SEI methods are exposed to the client.  
> The app has a POJO implementing the same methods as but not extending the SEI.

foo.FooWs.foo(java.lang.String) throws java.rmi.RemoteException with arguments java.lang.String.
 The arguments do not match the signature.
