I am generating a JSON String at client side that is in JSP page and send to the server means to servlet. And I catch that string in the servlet using getParameter(). But I cant access the single element from that JSON string in the servlet.Please tell me How can servlet reterive the single element from the String.

Eg. {"Iem1":"3","Item2":"4","Item3":"12"}

then I want only 3. How can I get that 3.

you can parse the String yourself with those String functions defined in java.lang.String.
or you can use some Java library to do it
www.json.orghave introduced many java api to handle json .

Why are you creating a JSON string at all if that's not what you need?
