I have had a few inquiries about whether it is possible to integrate Adobe Flex with ATG via AMF. My short answer is Yes. It should be possible. The only issue that needs to be solved though is to access the nucleus components from flex. You need a factory for that e.g. the equivalent of ejbfactory(used for EJB 3) for ATG. At some stage when I have a bit of time in my hands I will create a factory for ATG Nucleus, if nobody creates one in the mean time.
