I had the chance to present at the BreizhJUG (a Breton Java user group) a session named "Flex for Java Deveoppers".
A crowd of almost 100 happy Java developers and architects was willing to know more about Flex.
I had an an hour and half to cover :
a basic presentation of the flash and AIR platforms,
cool UX flash/flex/AIR demos
the latest great features of flash 10
and flex, and its ecosystem from a Java developer perspective (mvn framework, testing libraries, building and quality tools, blazeds, lcds)
I ended up the session presenting fna maven archetypes
