As I had said in your previous post on this same subject, this is a common question that has been discussed many times.

Essentially, you can either repaint the whole page by posting back to the server to add the new data using JSP, or you can use Ajax to fetch the new data from the server and populate the secondary dropdown using JavaScript.
