I'm writing a display manager these days, and I have two options: Flex
Well, as the next release of Adobe AIR will support UDP, I'm thinking
maybe I'll focus on Flex AFTER the AIR 2.0 will be released. But right
now, my Flex uses CAJ/JCA, Tomcat and ActiveMQ as JMS, that's tooooo
JavaFX still uses CAJ/JCA, and that's all. His problem is more
personal: not as beautiful as Flex.
I'm really looking forward to the release of AIR 2 even although it
means that I should write a CA protocol for it.
