Is it bad to reply to your own post? Sorry for my impatience. I have found an answer to my problem and maybe I can save others the reply effort.
>From Christophe Coenraets fine post on the matter ( http://coenraets.org/flex-spring/), I quote: "So, if Flex clients can remotely access Java objects, and if Spring beans are Java objects, aren't we all set and ready to start accessing Spring beans from Flex clients? AlmostÂ… There is one simple element to configure. The whole idea behind Spring IoC is to let the container instantiate components (and inject their dependencies). By default, however, components accessed remotely by a Flex client are instantiated by Flex destinations at the server-side. The key to the Flex/Spring integration is therefore to configure the Flex destinations to let the Spring container take care of instantiating Spring beans. The Flex Data Services support the concept of factory to enable this type of custom component instantiation. The role of a factory is simply to provide ready-to-use instances of components to a Flex destination (instead of letting the Flex destination instantiate these components itself). " Thanks
