The exception says :

java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContext .

It's a common error that appears when there is a conflict between libraries and its dependencies. You should try to execute your code in a test project with only the libraries from JAX-RPC, and then add one by one the rest of your app libraries.

Also, you should check your server libraries to discard any kind of conflict for having the same library (or its dependencies) in your app and in your server with different versions.
