How do I get JQuery to work with CakePHP?

Question

I use CakePHP 2.0

I am following this guide http://nuts-and-bolts-of-cakephp.com/2009/01/19/jquery-in-the-cakephp-world-part-1/

I have included in my add.ctp viewer

$this->Javascript->link('https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js', false);

and I have

var $helpers = array(‘Javascript’, ‘Html’, ‘Form’);

in my controller...

The error I am getting is

Missing Helper
Error: JavascriptHelper could not be found.

Error: Create the class JavascriptHelper below in file: app/View/Helper/JavascriptHelper.php

According to the documentation, if you're using CakePHP 2.0 then jQuery comes already packaged with the framework.

See here for more detail on how to use jQuery and the JSHelper in CakePHP 2.0

The tutorial you've linked to is for version 1.3, so that's why it doesn't work....
