I think you may look into this package
org.apache.wicket.extensions.ajax.markup.html.form.upload where upload
progress-bar is implemented. You may do something like this.
So, probably it sets a resource in session, Java part regularly updates the
string resource. And JS keeps on polling this resource by using the URL to
the resource provided to JS initializer and renders on UI. Anyone can
correct me, if I am wrong.
Just a suggestion. I am naive to Wicket.
