JsonpRequestBuilder has a default timeout of 10 seconds, whereas RequestBuilder doesn't have a timeout by default. http://www.gwtproject.org/javadoc/latest/com/google/gwt/jsonp/client/JsonpRequestBuilder.html#setTimeout(int) Anyway, if you can setup CORS on your server (Access-Control-Allow-Origin response header whitelisting your client, or simply "*"), better use that and RequestBuilder than JSONP (better error handling, much better security, etc.): http://caniuse.com/cors
(talking about security: use com.google.gwt.core.client.JsonUtils to parse JSON, *not* eval() !)
