> I've deployed a JAXWS web service that uses JAXB binding classes on the client and the server. I get a NullPointerException when attempting to call a web method with the following signature:
> public String[] webMethod(Object token, List<String> listParam, boolean boolParam)
> I traced the problem to the setReturnType method of the org.apache.axis2.jaxws.description.builder.converter.JavaMethodsToMDCConverter class. Instead of returning an array class as the type, the method.getGenericReturnType() method returns a GenericTypeArrayImpl object. Since this type isn't handled in the if clause of the setReturnType method, the return type on the web method is set to null.
