Using DWR with Struts forms

Hi.
In order to implement a simple CRUD functionality using Struts, I created a simple Action and mapped it twice to different URLs.
CRUD operations operate over session-saved data.
The application works smoothly without any propblem.
But in fact, I want to re-implement this CRUD using DWR so the user won't see page reloading.
I checked this page : http://getahead.org/dwr/server/struts

The page says :
"This will allow you to make calls into your FormBeans from DWR."
What does this mean ?
I should extract managing-cart-methods from my Action and put them into the ActionForm ?
I failed to find an on line example.
Thanks.

I did a Struts project in which I used DWR extensively to perform AJAX Functions. Frankly, I didn't find any use for the Struts creator. All it does is allow you to access your form bean. If the information I need is in the form bean, I can access it easily on the server side in my JSP. I don't need AJAX to get information from the form bean.

I just used the regular javabean builder that is used in most of the examples on the DWR Site.
I should extract managing-cart-methods from my Action and put them into the ActionForm ?

No, I wouldn't do that. Here's what I'd do: I'd take your managing-cart-methods out of your Action class and put them in a regular Java class. Then just register the class and methods in your dwr.xml file and make AJAX calls to them using the DWR interface.
