I asked my nephew to use Flex instead of JSP for his college project, and here is what he has to say after a few hours of work in Flex.
woow nw im enjoying using flex… making use of containers, Accordion, TabNavigator… many more stuff, displaying things in alertboxes having nice fonts… so many options to add in a simple project!!! will work for 4-5 days on frontend then will switch to blazeDS!!!
Kudos to the Adobe team.
