Flex and Seam == Flamingo
JBoss (Exadel) has been working on a new open source project called Flamingo. It looks pretty slick and supports a home grown AMF protocol under the covers as well as bundling Hessian support for remoting.
They’ve posted a demo and documentation in the form of a user’s guide, APIs and other docs.
And for people that know me…it’s built on Maven.
