Hello,

I am a beginning developer trying to develop a very simple, basic store using Netbeans Visual JSF Web Application.  I've already developed the layout and design of the page, but I'm having some trouble implementing the business logic.

Specifically, what I'm trying to accomplish is passing numbers enter in the Order Quanity fields for each item to an "Order Summary" page that displays the items ordered, quantity ordered, and pricing for each.
How can I pass the data from my main page to my summary page when the user clicks the "Submit Order" button?  Then, how can I calculate the data and then display the results on that Order Summary page?  Specific advice or relevant examples would be greatly appreciated!  

Thanks in advance!

When working with "Visual JSF Web Application" by default you have an Application Bean, a Session Bean, a Request Bean and a Baking Bean for the first page.

You can use the Session Bean and the Request Bean to pass information among the whole session (using the session bean) or just a request (using the request bean). More details here http://www.netbeans.org/kb/60/web/scopes.html.

The business logic for caluclation can reside inside the page bean. For example int page bean of the summary page inside the preprocess method you can fetch the data from your session/request beans do the calculations.

In general a lot of usefull examples can be found in: http://www.netbeans.org/kb/60/web/index.html

I would suggest you to review all of them if you intend to use visual jsf.
