dropdownlist

Hi,

I have two dropdowns in my form. The first one Queries for a set of data and displays them. Based on the value selected in the first dropdown i have to query the database, using that selected value as a parameter and populate the second dropdown. In short, based on the first dropdown, second one has to be populated dynamically. Am coding in JSP. Please do help on this!

Thanks, Geetha
