       Resolution: Fixed
    Fix Version/s: 2.1.7
         Assignee: Daniel Kulp  (was: Sean O'Callaghan)

The attached test case, which indeed fails with 2.1.4, runs fine with 2.1.7 so marking resolved.

> 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?
