Well, the use case was a little different here: I'm trying to
overload ActionLoader so that you will be able to call
exec(data, "myAction")
which will end up calling perform(data), or
exec(data, "myAction", "doMyMethod")
which will end up calling doMyMethod(data) in class myAction.

Ok, this would mean changing the declaration of method
protected void perform(RunData data);
to public... However, the comment for the method says:
"This method is protected to force clients to use
ActionLoader to perform an Action."
Another way of doing this would be to simply call doPerform()
from exec(); this is all perform() does anyway, and doPerform()
is public. Since I'm not familiar with this code, would you
think this is a better approach? What is the purpose of method
perform(), anyway?

This happens with:
doEvents() in ActionEvent, VelocityActionEvent and
WebMacroActionEvent.
doBuildBeforeAction() and doBuildAfterAction() in several
Page-derived classes.
doRedirect() in TemplateScreen.
doOutput() in RawScreen.
doStartTag() and doEndTag() in JSP classes.
Just thought I'd mention it...
