Unable to generate JAX-WS artifacts

I downloaded Custom Object 10 wsdl and use JDeveloper 11g to generate the JAX-WS artifacts but I got errors as below.  Below are my ANT script and errors. 
It's working fine with when I generate JAX-RPC artifacts. I only have problems with JAX-WS artifacts.

Do you have any ideas?

Thanks,
