StatusCodeException Vs. RuntimeException in GWT

Question

In my GWT app. I overrode RemoteServiceServlet to check if the session is valid right before the service method is being called. I am trying to throw a RuntimeException(\"ex

Answer 1

The post looks too old, still here is the solution I have come up with. Override processCall(String payload) of RemoveServiceServlet, if the session is invalid execute the blow code else call super.processCall(payload).

//Pass the exception to Client
RPCRequest rpcRequest = RPC.decodeRequest(payload, this.getClass(), this);
onAfterRequestDeserialized(rpcRequest);
return RPC.encodeResponseForFailure(rpcRequest.getMethod(), new CustomException("Invalid Session!"),rpcRequest.getSerializationPolicy(), rpcRequest.getFlags());

All the GWT services are servlets so GWT serializes the custom exception and sends to client as string, we follow the same :)
