You have two choices: - Return anything but a 200 status code, to trigger a "request transport error" on the server-side (handled by the RequestTransport on the client-side; it's generally used for authentication, as in the Expenses and Mobile Web App samples for instance) - Send back a "general failure" message. Use the MessageFactory<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/web/bindery/requestfactory/shared/messages/MessageFactory.html>AutoBeanFactory to create the message and AutoBeanCodex to serialize it. The message should consist of a ResponseMessage with a non-null generalFailure ServerFailureMessage. The other properties can (should) be null. The ServerFailureMessage properties map directly to the ServerMessage properties passed to the onFailure of the various Receivers. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
