You could transparently handle this for all your requests of a given GWT-RPC interface by using a custom RpcRequestBuilder. This custom RpcRequestBuilder would make 3 request attempts and if all 3 fail, calls the onFailure() method.
MyRemoteServiceAsync service = GWT.create(MyRemoteService.class); ((ServiceDefTarget) service).setRpcRequestBuilder(new RetryThreeTimesRequestBuilder()); The custom RequestBuilder could also fire a "NetworkFailureEvent" on the eventBus if multiple application components may be interested in that information. For example you could overlay the whole app with a dark screen and periodically try sending Ping requests to your server until network comes back online. There is also the onLine HTML 5 property you can check, but its not 100% reliable (https://developer.mozilla.org/en-US/docs/Web/API/window.navigator.onLine) -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
