The thread started out being about WebMacro and JSP. I guess the message
you responded to was talking about a different template system, and I
didn't notice the change. Sorry for the confusion.

You said it was possible to put in or leave out Java code in the
template (JSP in this case). I claim this is a bad thing, since it
encourages you to put logic in your template.

Then it's likely you haven't properly prepared your data on the back
end. The usual solution is to construct some kind of Iterator in the
back and have it loop through just the values you want--possibly
manipulating them in some way as it goes.
I would claim that the point at which your template script loop isn't
powerful enough is exactly the point where you are starting to put
business logic (or at least session logic) into your template.
Note that under WebMacro you do have full access to 100% pure Java.
It's in your ordinary looking Java servlet that just so happens to
return its HTML by loading and executing a template. Prior to
executing the template, it can do whatever it wants.
Why limit yourself? Java's a great language for implementing session
logic.

I am the principal creator of WebMacro, so I'm clearly biased. I don't
"work for them" because WebMacro is a free software product, available
to everyone under the terms of the GNU General Public License (if you're
not familiar with it, the same license that covers GCC, Linux, etc.)
For the record most of what I say also applies to the contrast between
FreeMarker (another good template system) and JSP. FreeMarker should
win vs. JSP for the same reasons that WebMacro does (in my opinion).
I wrote WebMacro because I hold these opinions.
