HowTo: JSP Progress Bars

As web interfaces become ubiquitous, more and more complex back-end processing is necessary. Of course, stateless HTTP leaves few ways to tell users what's going on. Andrei Cioroianu presents a JSP technique to display application "progress bars." [ONJava.com]

It's too bad there's so much scriplet action in this example, but the lesson is good. It'd be even nicer to see a JSTL port of this howto, or an alternate view approach (i.e. using Velocity or XML/XSL).

I've found XML-RPC to be great for client-server communication. It would be trival to create an XML-RPC web service that takes a taskID and returns a percentage. The client page would call that service every 10 seconds or so via JavaScript and update the progress bar accordingly. A good client-side XML-RPC library is at http://www.vcdn.org/Public/XMLRPC/ and of course a good server side library is at http://ws.apache.org/xmlrpc/.
