Re: Empty Response From HTTP Request
All web services were returning json but not in a way that is treated as jsonp for the GWT client. Once that was fixed no more timeouts occurred for future requests. However there is now a bizarre issue where the ArrayList that was populated in the defined onSuccess method (for the AsyncCallback object) is now empty outside of the method definition. How can that happen when no items have been removed from the ArrayList? The ArrayList was defined outside of the object. On May 13, 5:34 pm, A.

Re: Empty Response From HTTP Request
As it turns out AsyncCallback doesn't have a way to inform that it is finished. Therefore anything that needs the proper results from the request would need to be done in the AsyncCallback's onSuccess method.

Re: Empty Response From HTTP Request
Hi Nick, Are you saying that the server response is empty or that RequestBuilder does not recognize the response? If its the former, the server is not recognizing something in the request like the browser code headers. If its the latter, then I would compare the content-type and formatting of the response with a benchmark response from the eclipse dev tool. Either way, you'll need to get below just looking at the browser display to understand diagnose the communication protocols. I suggest using a logging proxy server on your test bench to track what is coming and going. MS Fiddler works well on Windows. ---Stevko On Wed, May 11, 2011 at 3:14 PM, Nick Apperley napper...@gmail.com wrote: Using RequestBuilder I can successfully make a request to the Glassfish 3.1 server I have setup.

Re: Empty Response From HTTP Request
Every time a request is made with RequestBuilder an empty response is returned from the server. If the request is made using just the web browser in an empty tab a non empty response is returned from the server that is displayed directly (in Firefox). With the latter the expected response is returned from the server. After doing some further investigation on the issue it seems as though the empty response could be caused by GWT's Same Origin Policy. The web services are running on a different server from the GWT client. What was suggested was to use JsonpRequestBuilder instead of RequestBuilder to bypass the SOP problem. However that can only be done if one can change the REST web services to return Json instead of XML. I have undertaken the suggestion but now have an entirely new problem to content with. Timeouts are occurring every time a request is made using JsonpRequestBuilder. I have checked to see that the URL is correct, and have extended the timeout duration but still end up with the same problem. What could cause a timeout to occur with doing a request with JsonpRequestBuilder? A.

Re: Empty Response From HTTP Request
What is really weird is that the timeouts are occurring with making a request via JsonRequestBuilder yet the Glassfish server has received the request successfully. I have been digging through the Glassfish server logs and found an identical set of entries for 2 requests that were made (one from GWT client, the other from the web browser). What isn't recorded in the logs is if the server has sent back a response, and its content if it was sent. Right now I do not know what is happening with the server responses. Presumably a response is being sent back to the GWT client. At least a response has been sent back for the request made by the web browser.

Empty Response From HTTP Request
Using RequestBuilder I can successfully make a request to the Glassfish 3.1 server I have setup. The server delivers REST web services that involve HTTP GET and POST.
