I am posting a jQuery AJAX POST to a servlet and the data is in the form of JSON String.
Its getting posted successfully but on the Servlet side I need to read these key-val pairs into a Session Object and store them. I tried using JSONObject class but I am not able to get it.

Heres the code snippet

```
$(function(){
   $.ajax(
   {
      data: mydata,   //mydata={"name":"abc","age":"21"}
      method:POST,
      url: ../MyServlet,
      success: function(response){alert(response);
   }
});

```

On the Servlet side

```
public doPost(HTTPServletRequest req, HTTPServletResponse res)
{
     HTTPSession session = new Session(false);
     JSONObject jObj    = new JSONObject();
     JSONObject newObj = jObj.getJSONObject(request.getParameter("mydata"));
     Enumeration eNames = newObj.keys(); //gets all the keys

     while(eNames.hasNextElement())
     {
         // Here I need to retrieve the values of the JSON string
         // and add it to the session
     }
}

```
