Hi All,

I have an AJax call in a Jacascript function which would go to an Action class. Based on the value sent I need to send back an ArrayList, in short I want to know how to handle an Ajax response and the best way to send value from action class.

You can convert that List into JSONArray or JSONObject and write the same on OutputStream.
On the client side , in success event handler ( Whatever you choose to implement Ajax on Client Side), parse the JSON String JS libraries and use it further to fulfill the requirements.

Refer http://json.organd
