How would one update indexed properties with Struts?

[Shamdasani Nimmi-ANS004]

Hi All,

I have a bean  userOrderListBean with a property 'getOrderList' which is a list of 
'Order' Bean. I would like to show the rows from getOrderList to the user on a JSP and 
allow them to update the information.

How does one update the indexed properties using Struts? And does userOrderListBean  
have to implement ValidatingActionForm?

If someone has an example I would really appreciate it.

Thanks in advance.
