I have spring session scoped bean. That bean is using application scoped beans, and there's and error when the container tries to serialize the session.
I remember that problem from JSF applications, and in one project, we've solved that using serializable proxies. The injected bean was the proxy wrapper which fetched the singleton instance from the application context. Unfortunately, I can't remember how exactly it was called and was it a build-in solution or some external thing.
How to wrap spring beans in serializable proxies? Does Spring provide such functionality? AFAIR there was some special annotation to mark the references that should be wrapped in such proxy.
