public static class IncompatibleRemoteServiceException
extends Object

Exception that will be passed to the AsyncCallback.onFailure(Throwable) method when an incompatibility is detected between a RemoteService client and its corresponding RemoteService server.

The correct response to receiving an instance of this exception in the AsyncCallback.onFailure(Throwable) method is to get the application into a state where a browser refresh can be done.

This exception can be caused by the following problems:

• The requested RemoteService cannot be located via Class#forName(String) on the server.
• The requested RemoteService interface is not implemented by the RemoteServiceServlet instance which is configured to process the request.
• The requested service method is not defined or inherited by the requested RemoteService interface.
• One of the types used in the RemoteService method invocation has had fields added or removed.
• The client code receives a type from the server which it cannot deserialize.

Note that on the client, the #getCause() always return null.
