You don't write user interfaces in JavaScript. That's HTML.Delan Azabani– Delan Azabani2010-08-17 08:32:03 +00:00Commented Aug 17, 2010 at 8:32

Maybe you should try to do a proof-of-concept, something simple that uses JavaScript, a button, sends a message to the server, the server parses it and saves something in BD. Then, when you are sure of how to do each part... think about a CRUD :)helios– helios2010-08-17 08:32:11 +00:00Commented Aug 17, 2010 at 8:32

jQuery is a JavaScript library that defines a bunch of functions to extend features and smooth out browser incompatibilities. I don't use it myself as I don't believe 'general' libraries are any good. If you can write it with JavaScript alone, why go and find a way to do it with jQuery?

You should get your JavaScript to talk to your servlet that is performing the CRUD actions. So your button "Create" calls a create method in your servlet. A easy way to do this is to use the Direct Web Remoting (DWR) JavaScript library - check their tutorial.

You should connect your javascript with a Web Service.
