But the warning against undue complexity in programming generally abounds.

It is.

This is where we disagree.

But as with all programmming, overly-complex and hard-to-follow code is
bad. It doesn't matter whether you're doing JSPs, POJOs or whatnot, the
problem is not with the tags but with the coding style.

Here too. I think java *always* allows a clearer, less complex and
easier-to-follow expression of logic than tags. I'm not talking about
undue complexity here, i'm talking about where to put due complexity.
