For the past week i have been researching Java Web frameworks, and ways to create something that i can do with php in a week. I would like to create a web application that allows me to create a java power clone of netvibe / pageflakes.However instead of widgets i want to have jsp application running in the window. What java web framework would allow me to do this? I have been looking at JBoss portal but it appears to be hard to style and add the ajax behavior to the windows. Cheers!

you can use GWT widgets to display other pages inside html iframes. http://code.google.com/webtoolkit/
