I think Eric is too modest. This is much deeper than the sugar and
vinegar he gives himself credit for. This is positively Sid Hartha!

The answer to your question, Eric, is that neither pattern is in
commons-chain, as you suggest. The commons chain is a Chain of
Responsibility pattern. My concern was with the Struts classes, and I
think that I have received an answer on my inquiry, viz. that a
refactoring to a Strategy pattern i

If I remember it correctly, tag is used to produce
anchor/hyperlink tag in html (i.e. tag). What you need here is a
tag or a style tag .
I would very much go with James' method.

Back in town (for at least one day), and snipping off the flamebait

I guess here's a way I can restate my question.
I'm with you on choosing composition rather than inheritance when it's
possible and sensible. But it's not always obvious where and how
inheritance can be replaced by composition. I find it to be a
challenging part of programming. So that's why I b
I guess I focused on the "backward compatibility" issue, which I did
not understand at all. Thanks.

I think I stated the problem badly, Eric. If you look at the
implementations of commons-chain you will see the implementations tend
to use Template Method. The chain is used to solve the rather
troublesome problems with that pattern, and yet the people who go to
all the trouble to change to chain
I think it's probably usually good to question Template when the
realization of it comes via class inheritance.
However, I'm confused. I read Bill's article (first pass anyway -- and
I'm new to Commons Chain), and I'm still not seeing where exactly
Template is implemented in Commons Chain. He i

But, I do think you are right about this and probably this is
really ineffective.

Thanks Bill - at first I wondered why I didn't see it earlier but I

I'll have a read and hopefully it'll all make sense to me!
Thanks

Hi,
After searching around the Net and on the user/dev Struts mailing
