The jax-ws annotations need to add both on SEI and the concrete service class

[Damon]

Like targetNamespace, if only add it to SEI, it didn't work. I have to add it 
to both SEI and the class.
But the CXF user guide said that the only nessesary annotation for concrete 
class is endpointinterface.
 
So is there any other annotations need us to add them both on SEI and the 
service class?
