I saw the same issue in many different locations and even after a good portion of googling, I could not resolve it. What I am trying to do (the bigger picture) is to go through

The issue is due to the relevant jaxws jar not being in the class path see the pathelement node above. Adding the jar to the classpath resolves the issue.
