Do you accidentally have enabled AppEngine in your project settings (the error message looks like it is generated by AppEngine)? If so, deactivate it. If you plan to deploy to AppEngine then do not add the javax.mail.jar into your WEB-INF/lib folder as AppEngine provides the JavaMail API on its own. If you use Maven make sure javax.mail.jar isn't added to your dependencies by some other library you use.
You should never ever have more than one javax.mail.jar on classpath. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
