The first problem with that is that this stuff seems show up
*everywhere* in Javaland. It's not just web apps, it's pretty much
anything. Second, just because a *problem* is complex and would
benefit from Clojure doesn't mean that the requirements for deployment
are complex and need more than a simple cgi (for example!) would
require. Yes, when the choice is 150 lines of C with 0 lines of config
vs. 20 lines of Clojure with with 10 lines of config, it doesn't look
so bad - but 30% of the work being overhead still sucks.

I didn't ask "how do I deploy a .clj script on a running Tomcat". I
asked "how do I go from a .clj script to an application running on
Tomcat"? I can't deploy a C program on running Apache server either -
I have to compile and link it first. Not a problem. My 3/0/1 solution
could just as well have been:
$ cat - > hello.c
main() {
puts("Content-type: text/plain\n\nHello world!\n") ;
}
^D
$ cc hello.c
$ cp a.out /usr/local/apache22/cgi-bin/helloworld
Anything even close to that for Tomcat and clj?

Good advice. That's what I've been doing so far. On the other hand,
I'd rather spend my time building the things that interest me rather
than reinventing wheels for which I already have adequately round
examples. If my expectations of "adequately round" are much higher
than the communities, then I'll wind up doing to much of the latter
and not enough of the former, and will probably be happier elsewhere.
