Hi,
I am using struts framework
I have a jsp page where i have 3 list boxes in which i need to populate the data on the page load
but i have to populate the data in the second list box after selecting a value in the first list box WITHOUT MAKING A DATABASE CALL.
when i first load the page i need to save the data somewhere
any ideas
i have Business Objects, Transfer Objects,ViewHelpers in my project
where can i implement this logic and how to do it any suggestions please!!!

The term used for this type of control is "dependent dropdown" or "dependent select". If you Google either of these topics, you will find a lot of suggestions about how to do it.
This topic has also been discussed recently in this thread

When you say "WITHOUT MAKING A DATABASE CALL" do you really mean "without refreshing the page"? If so, I would recommend an Ajax based solution. As long as your lists are not too large, loading the data into the page and using client-side JavaScript is not too bad of a solution either.
