I agree that this is a perfectly appropriate and fine use of
run time class info, given that you've got a method name as
a string. I don't know anything about what it is you are trying
to accomplish with your servlet, but I wonder if there was some
other way to define it such that you can customize not by
adding a method then giving a method name, but by simply adding
a subclass and giving the class name as a CGI parameter.
I usually think of customization by type.
