Sping MVC: Bind JavaScript array to ArrayList

I need to bind a JavaScript array to an ArrayList. Using JQuery in a Spring MVC web application.

The ArrayList is to have it's elements' reordered on the web page by the user via JavaScript. The backend code had been taken care of, I now need to find a solution to map the JavaScript to the ArrayList.

Does anyone knows a good way to do this?

I feel like this is a bit of a JQuery specific question. I've used ExtJS and Yahoo's YUI and in each of those the binding of a JavaScript variable to a Java variable is different (it is way easier in ExtJS BTW). I don't know how it's done in JQuery but in both ExtJS and YUI there is a JavaScript object that you bind via AJAX to the back end (basically a doGet in a servlet). Does JQuery work like that?
