From your error it appears you are trying to use the CustomerEntryImpl class from the client side code, even though that class is in the server package. That class extends a servlet (RemoteServiceServlet), and web browsers cannot run servlets.

Check your module files to make sure you are not adding <source> tags to point to any package which has server code in it, and make sure not to reference server classes from your client code.
