GWT + REST + JSON

Hi all,

I am new to GWT.

I have an application that runs on Flex client. I want to implement a GWT client (GWT + REST) for the same backend implementation.

Parameters are passed using JavaScript Object Notation (JSON) within the request body. The response consists of a standard HTTP status code and an optional JSON response body.
A list of items to be fetched based on user-specified filter criteria. The filter criteria include any combination of content and paging/sorting attributes.

The contents in the JSON response is a set of values that have to be displayed on a lazy scroll table on the client side.

I tried my best to find some examples online that is close to the implementation I am working on. I did find some examples (RESTlet + GWT , Resty), but I am not sure if I am on the right track.

How do I send a JSON object request to a particular URL? How do I display the content on a lazy scroll table?

Can you please help me by suggesting ways in which I can implement the same.

Thanks in advance.
