OK, your onchange code is going to have to use an XMLHttpRequest: http://developer.apple.com/internet/webcontent/xmlhttpreq.html
and http://www.google.co.uk/search?hl=en&q=XMLHttpRequest&btnG=Google+Search&meta= It will use one of these objects to send a request with whatever parameters are needed to producde the new combobox data back to a servlet which will send back a response. The way I do this is I have the servlet send back a response of type "text/javascript", and send the javascript code to call those DOM methods and update the second combobox. (You did read those DOM documents didn't you?) Back in the browser, in your javascript onreadystatechange handler which processes the response when the readyState == 4, you can eval() the responseText, and it will be executes. NB: Put a try{}catch{} round it so that you can highlight bugs in your returned javascript... takes a while to write bug-free javascript, especially when you have to compile your servlet and run your app to get the javascript out into the browser. Don't forget to do a setTimeout() to call a failure method after a certain time - which is cancelled by the onreadystatechange handler on success - to handle server non-response!
