thanks bricemason,
I have checked the thread in detail.
is there any custom options possible to access data from this type of json service?
Thanks

I'm not sure what you mean. If you decided to go the route of writing your own server-side implementation to access this service, then you'd probably use an ajax proxy. You can review the options for that proxy here:

thanks again,
i need to access json service using jsonp request (cross domain).
Is it possible to implement such a call?
Existing service is having json response without root element.

A jsonp request is not possible with this service because it's not returning jsonp. It is returning json. Read these docs to learn more about jsonp:

http://docs.sencha.com/touch/2-1/#!/...ta.proxy.JsonP

You can solve this using the other ways that I've outlined in the previous threads. Do you have access to your server-side code? If so, what is the platform (PHP, Java, etc)? One way to solve this is to use your server-side code to make requests against the service you want then pass through the results to your client-side code.

But again, the short answer is that this service you're attempting to use is not returning jsonp so you can't use it that way.

thanks Brice,
i got a better understanding now, i dont have access to the server side, i will try to find some other alternative solution.
