Anyone has a recommendation on the best (or at least good) book on Portlets. It looks like I am about to jump into a large project that uses portlets as a component for a large part of it.
BTW, I know absolutely nothing about portlets. For example, this project also makes references to flash... and I don't know if the two technologies related, or just another technology that is used. (Which leads to a side question for the best book on flash. )
Don't know of a book, but I got my start into portals with Jetspeed 1. There are a fair number of articles and examples available for it. It's got a non-trivial learning curve, though, so if you're really interested in a particular portal, it might be better to start with that one. Jetspeed 2 has the advantage of implementing the relevant standard JSR-168.
