javascript combobox

Hey, fellow coders

I need a little help. I am developing an online railway reservation system. What i need is, when the user selects a train number from a combo box, he should be able to view the list of sources and destinations for that train number dynamically. The sources and destinations are present in a sql database which i am accessing through servlets. So everytime he selects a train number the train number should be sent to the servlet, retrieving the source and destination from the database and displaying it in the browser.

I was wondering if this possible. Any help would be greatly appreciated.

Thank you,

Tony.
