Class IncompatibleRemoteServiceException

    java.lang.Object
      java.lang.Throwable
          java.lang.Exception
              java.lang.RuntimeException
                  com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException

All Implemented Interfaces:
  IsSerializable, java.io.Serializable

    public final class IncompatibleRemoteServiceException

extends java.lang.RuntimeException
implements IsSerializable

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 `Throwable.getCause()` always return `null`.
