I'm curious to know the status of the Geronimo Spring integration. The last message I see is from Jeremy who was looking into an upgrade of cglib to support the work that Jules is doing. Has there been any progress beyond this to date? Jules, do you need any help with this integration?

Bruce,
Thanks to Jacek's moving us to cglib 2.0.2, I have just checked back in my updates to the spring module.
The current state of play is that the spring deployer defines a new module type: '.spr' (I suggest a pronunciation of SPAR - SPring ARchive).
A .spr can contain classes and (one level of nested) jars in its root dir, along with a spring.xml in its META-INF dir.
The spring deployer sets up a SpringGBean along with the relevant parts of the original .spr to be loaded at runtime. Note that we are currently constrained into pushing pretty much all of Spring's runtime complexity into the Geronimo runtime, although it would obviously be much better to do a large amount of this work at deploy time.
The spring module defines a SpringGBean, which when loaded, configured and started, will pass the META-INF/spring.xml to Spring, then take each resulting Spring-managed bean and using a subset of its complete API (just obvious properties), create an interface and from this a proxy class that can be loaded into the kernel as another GBean. The kernel creates an instance of the proxy class and the SpringGBean injects this with an invocationHandler which delegates all activity to the Spring-managed bean in question. Thus Spring POJOs are made to appear seamlessly integrated with Geronimo.
There is much more to be done, but what is currently there should allow you to deploy simple Spring apps (how simple I'm not yet sure - my test app is VERY simple:-) ) and then find the corresponding GBeans in the debug-tool.
I am running the server with the following config :
org/apache/geronimo/SpringRuntime org/apache/geronimo/SpringDeployer org/apache/geronimo/DebugConsole
I'd be very interested in any feedback that the list might have, and will keep posting as we add new functionality.
Cheers,
Jules
