I find the solution!!! If you are using Google App Engine (separate from GWT), you cannot use an external database. App Engine doesn't allow you to open socket connections, and that is exactly what the getConnection() method does. So, if tou would like to use mysql in your GWT app with "google web toolkit developer plugin", you mast disable "Google App Engine" in the properties of the project (propertyes->google->app engine)... and finaly mysql works with GWT developer plugin!!!!!!!
