The server is running at http://localhost:8888/

Answer 1

It probably means that port 8888 is already in use by some other service (Java server?) - if you're using Google Eclipse Plugin, you can specify the port in the project settings, otherwise use the --port parameter.

Answer 2

You may have already started a server running your GWT application (or just any other server), which you will have to stop before you can start another one. Or do like Igor said and start your GWT server on another port.
