You cannot return StreamingQueryResult from your RPC Method. The RPC Method must return an object that implements Serializable and has a default no-args constructor. Also, this class should not depend on any server specific class.
Remember - the object you return from your RPC method will ultimately be converted to javascript, so you really cannot return any arbitrary class.
