I just got done checking out the various solutions out there for
generating HTML from servlets, and chose webmacro. I spent a lot of
time looking at JSP, especially because it's a Javasoft thing and
widely supported, but I saw a couple of big, very practical problems
with it:
1) I want to have a website where users have to log in. If possible,
it should work like the Java Developer Connection, where a set of
servlet-served pages can be protected. Once a user has logged in,
they're sent back to the original protected page they requested.
This is *trival* to do with normal servlet programming. Lots of
articles have been written showing how, for example, with inheritance.
This is *hard* to do with JSP. I think it's because of the
control/execution model. I finally found an article at one of the
servlet sites showing how, and it was nasty. A real hack with
tricky/non-understandable code. Plus, a special #include and if/then
block has to be put in each protected page.
Webmacro uses the normal servlet execution model, and implementing
this was very easy.
To generalize: Authentication is orthogonal to the other processes,
and JSP forces it to be highly coupled to everything else. Another
orthogonal feature I want is transparent multi-lingual support. I
imagine thatthis would also be nsty to cleay implement with JSP
(especially if the authentication hack is there too!).
2) Webmacro's idea of *not* using HTML or XML-like tags is great. Any
html editor can be used to edit the templates w/out problems.

And to the original question: Advanced Perl programmers use CGI.pm -
basically what ECS is, as I understand it.
