Here's what I think you do:1) Deploy the flex.war file (this is the
empty WAR file youuse to start new FDS apps) onto your test/development
server.2) Modify configuration files, create and test assemblers,define
resources, as necessary. Create MXML and AS files, compilethem, define
HTML wrappers, etc., and store them in or under theweb application root
(not under WEB-INF).3) Zip up the app into a WAR file and deploy on
otherservers, as necessary.HTH
