Right now a lot of my applications use GWT-RPC for retrieving POJO's from a GWT RemoteService which in turn calls a Web Service (SOAP) to get the data. I am evaluating Flex and didn't really see anything truly analogous to this simple architecture. Anything I may have missed?

AMF is Adobe's compact binary message format for use in Flash / Flex applications. BlazeDS is the open source reference implementation for Java, using essentially nothing more than a simple "message broker" servlet to handle requests. This is similar to how services are exposed in GWT, although Blaze uses a single servlet, not multiple as in GWT.

Cool Blaze looks pretty close to what I'm looking for. – Mike C. May 28 '09 at 22:44

Anyone know the efficiency in terms of size of data transfer of AMF vs GWT-RPC? – Fletch Nov 16 '11 at 10:23

Does this help you? I'm not too familiar with GWT-RPC, but is the AMF protocol what you're looking for?

As others have mentioned, the main choice here is BlazeDS, which is Adobe's open-sores server product for exposing flex-native server RPC and messaging. BlazeDS on its own is a bit clunky, and if you use Spring on the server, there is a slick integration available between Spring and Blaze.
Another, 3rd-party alternative is GraniteDS, which does much the same thing as Blaze, but is Spring-friendly out of the box, and does quite a lot more than Blaze (e.g. runtime compilation and generation of SWF files from the webapp). I haven't tried Granite, but it looks pretty good.
