We have a new requirement driven by user interface team to go with portal solution for our user interface with portlets just like iGoogle. Our enterprise architecture team is recommending Portal technology (JSR 168) and personally but I think it is over kill. After reviewing Pageflakes architecture I am wondering whether we can come up with a lightweight UI framework to accommodate this instead of going with portal technology. I would appreciate your kind advice.
