Hi guys
I want to populate a list item ie drop down menu on the basis of the selection user has made in the previous dropdown - very much similar to Select Location >> India and then on the basis on India another list will be populated that will contain the states.
How should i go about it? i'm using JSP and all the values have to be read from database
should i use request dispatcher or refresh te same page with additional parameters passed as query string?
pls help

you can do it in both ways, either request server to query out the DB and send the results back to the same jsp page or you can have all the stuff with you on the client side and do this with javascript.

and wht you are saying sounds fine. you can use request dispatcher and refresh the page.
