Based on the number of JavaFX sessions at JavaOne, Sun is trying to push it pretty hard and will likely make a big announcement regarding JavaFX release.
Exadel is going to JavaOne this year. We have been exhibitors for the past 4 years. One of the products we are going to show is a lightweight integration between JavaFX and JBoss Seam/Spring. It will be based on Exadel Flamingo. Right now we already have Flex-Seam integration.
