This is all cool, but, I think, overly complicated for what you need.
I think a better solution, simpler and less archane, would be to
create a helper class that constructs the appropriate ActionForward
given your needs/rules.
SomeAction extends Action with execute(...) { .... return
ActionForwardCreator.createActionForward(...[parameters]...); }
