Anyone interested in using Flex 2.0 beta with Ruby on Rails should head over to my good friend Stu Eccles Rails blog and check out his tutorial on setting up a Flex 2.0 and Rails application.
I’d recommend having a browse through his blog as there is some good information there. Oh and if you ask nicely he may even post some stuff up on Java and Flash / Flex development. Anyway enough trumpet blowing stop by liverail.net and see for yourself.
