What I'd thought of was adding an extra method to Action and
ActionSupport. The Action method's signature might look like this:

public String handleException(Throwable t) throws Throwable;

The ActionSupport implementation:

public String handleException(Throwable t) throws Throwable {
throw t;
}


I like it, but I would make it an interface:
  public interface ExceptionHandler extends Action {
      String handleException(Throwable t);
  }

and then have an interceptor which will catch the exception and do the right
thing if the action instanceof ExceptionHandler.
