Client error

Hey,

I've put together a basic web service that is meant to return the results of a query made to a mysql db. However, when the client queries the web service it returns the following error.

Exception in thread "main" AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: java.lang.NullPointerException
faultActor:
faultNode:

faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

Has anyone got any idea where this error is coming from? I don't know where to begin looking. Its some kind of null pointer exception but im sure where its originating from
