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