I recommend the AJAX solution if you can use JavaSript. I recommend NOT submitting the page every time you select a value from the dropdown box. 1) This is an interruption in experience and is interpreted as a slow website because it isn't immediate to the user and they are not even sure why it is submitting. 2) You will be dramatically increasing the bandwidth you use. Multiply the number of options in your dropdown box by the number of fields on the page by the number of users you're expecting. The server has to do extra transfers of the form data to and from the user.
I recommend that you make an additional JSP page and put the second dropdown box on it. That way the first page will submit. You can populate the list of values and display the second page with the second dropdown. The second page should NOT have the first dropdown box on it. Shawn D.

Take a look here: http://sourceforge.net/projects/javawebparts/ Grab a copy of the JWPCookbook. In it is a recipe called Dynamic Double-Select, which is exactly what you want. You should be able to take that example as-is and use it in your own app without much trouble. If your are Javascript-averse though, your only real choice is a two-step approach, i.e., show the page with the first dropdown and a button which submits the form. Then display the page with the second dropdown and two buttons, one to continue on and one to go back and select another option from the first. -- Frank W.
