Description

I have created my own WSDL and its 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?
