The accepted answer in that post is not just about rendering jsp variables to view. Have you tried something like `var jsvariable="<%= json %>";`? — ivan.sim, Oct 26 '14 at 08:37

You can traverse thorough the object in the javascript to print its key and value ,

function inside_obj(o) {
    var Otype = typeof o 
    if (Otype == "object") {
        for (var key in o) {
            print("key: ", key)
            inside_obj(o[key])
        }
    } else {
        print(o)
    }
}

Js runs on the client-side, whereas JSP - on the server side. Therefore, if you want to parse your JSP output HTML on the client side, you'll need to select this output (using jQuery is the most convenient way. Make sure you output it in a HTML tag with an ID you can use in jQuery selector). Then, use JSON.parse() to parse the json.

Also, why do you need JS to process your JSON? Can't you do that on the server side? Unless you're using AJAX, I can hardly think of a reason not to completely process your model on the server side.
