It sounds like you're not using Struts but are trying to come up with
functionality similar to it. Is this not the slowest way possible to port
an app to what is essentially a Struts type framework? It's not clear why
you're planning a more complicated approach with threads running all over
the place and replicating Struts features instead of just using the real
thing.
