can a javascript json string be converted to a java object in java web? because i converted a arraylist to json string and send it to a jsp page, and in jsp page i want to iterate the json string, or is there any other way other than converting it to java object?

ie how can i use the name of the json string to set a input text box field.

[{"name":"john"},{"lastname":"nice"}];

and in input text

$("#textbox").val("namehere");

is it possible?

here are the steps that i am doing

i have a button which triggers ajax and in the servlet i parse a arraylist to json

ArrayList<UserProfile> users=new ArrayList<UserProfile>();

the UserProfile class is consist of name last name and email.

users.add(new UserProfile("john","garcia","[email protected]"));
users.add(new UserProfile("cena",brock","[email protected]"));

and i return it to the jsp

out.println(gson.toJson(users));

and when i receive in ajax

 //i want to access every element of the arraylist that is parse to json string
}

Oh my, to a Java object, this one is going to be hard ! –  adeneo Feb 1 '14 at 2:39
    
If I understand you correctly, then you want set the value with JavaScript, so you would have parse the JSON into a JavaScript object. And yes, either of those is possible, search for "JavaScript parse JSON" or "Java parse JSON". –  Felix Kling Feb 1 '14 at 2:41

There are any number of ways to do what it appears you're trying to do. In any case, if you have a JSON string, this is trivial. Search a bit and ask a specific question if you're having a specific problem. –  Dave Newton Feb 1 '14 at 2:42
    
@FelixKling it is the other way around i want to parse JSON from javascript to java object. –  the bosxcz Feb 1 '14 at 2:44

If i understood your ask, you can do like this code.

But, if your result is a array "of java objects", you cannot use a form, you need a table or list to display all data or the form data are replaced by last item of your array.

This is not java's object, just json iteration.

<form>
    <input type="text" id="name" name="name" />
    <input type="text" id="lastname" name="lastname" />
</form>

<script type="text/javascript">
    //your code

    success:function(data){
        for(i in data)
            $("#" + i).val(data[i]);
    }
</script>
