JSON formatting (Sending JSON via jQuery AJAX post to Java/Wicket server)

Question

I\'m using jQuery to post JSON to a Java server, but I think my JSON must be wrong. Here\'s an example of my data and how I\'m sending it:

var lookup = {

You have to use JSON.stringify:

$.ajax({
    type: 'post',
    data: JSON.stringify(lookup),
    contentType: 'application/json',
    dataType: 'json'
});

You should also specify 'application/json' as the contentType. By default jQuery will serialize objects with application/x-www-form-urlencoded (even if the contentType is application/json'). So you have to do it manually.

EDIT: Key for 'post' should be type, not method.
