I have created my own WSDL and their corresponding service and implementation
classes (annotated of course). When I do not use the wsdlLocation attribute
on jaxws:endpoint, the request I send to the service works fine, but when I
specify the wsdlLocation attribute, I get a
NullPointerException/UNMARSHAL_ERROR from the XmlBeans databinding used by
CXF. Any ideas where I am not doing it correctly?
