That might be slightly off-topic, but it fits to the subject. However, personally I think that webwork is quite slow once you do some serious work with it. We are testing a webwork-based website on a P4 3Ghz plus 1 gig of RAM and some requests really do take ages (especially when the ValueStack is involved) to complete. I hope you find some ways to improve it before WW2 goes final.

Well, about a year ago when we had the initial XW meetings, it was
decided to keep the TL for now. Maybe post-2.0 we'll find ways to slowly
migrate away from it. I agree though, ThreadLocals suck ass.

I like the way that PicoContainer has done it:
public interface ObjectReference {
Object get();
void set(Object item);
}
Then there can be a ThreadLocalObjectReference, or a
SingletonObjectReference as needed.
I've needed to change the way that things are stored in Pico, and it was
a 5 line change due to this abstraction.
So you have the ActionContext take an ObjectReference of where to store
itself?
Cheers,
