Solution 1:

There is no need to pass the full path while specifying the URL. You can remove the localhost and port number '3849' from the URL. If you are using FireFox, use 'fire bug' plugin. It will tell you what URL ExtJS is posting and you can match it with the actual working url. In FireFox you can also use a plugin called 'RESTClient', it will allow you to send request to the server and you can check the response back.
