I will say that it is easier to create flashier stuff in Flash and not have to deal with the various incompatibilities. To do really cool stuff you have to have the latest of JVMs, and just having them download the JavaPlugin greatly reduces the potential audience. You can build far more sophisticated and complex things in Java - but until someone really gets on the ball with building flashy Java GUIs like you can with Viewlet Builder (it can actually do presentation style things *easier* than Flash) - I expect Flash to remain dominant in this area.
