Here is what I have done. 1) Extend RequestProcessor and register it in Struts config. 2) Override processPreprocess(...) 3) Put code in there that does what you need to do for access control.
I propose that Struts already gives you what you need to do this. The challenge is that Struts doesn't handle the kind of IoC and other dynamic delegation and interceptor stacks like Webwork does, for instance. So adding this kind of declarative or generic feature set for access control to the core Struts code tends to push the envelope a bit, since things are pretty tightly bound.
