Well, I am recently working on a project which required webservices to be consumed in Flash CS3. But surprisingly I found one can not use Flash CS3 to consume webservices directly. The classes were previously present, but removed. One of my colleague’s made it possible to work with webservices by compiling some Flex2 classes inside a SWC. But my curiosity does not end there as always. I tried to dig into the problem and found these two links, very useful.
The search still continues :)
