I want to run some java applications (not applets) on the server-side with
apache. Is there a more efficient way to do this than do just write CGI
programs in Java? I'm thinking of something along the lines of mod_perl --
but for Java.

I made a modification to mod_cgi to allow OS/2 to run
arbitrary (awk/perl/sh/...) scripts instead of just REXX
scripts and binaries.  There's already code in mod_cgi
to catch CGI programs with ".CMD" (REXX) extensions.

If you put such a trap in for some arbitrary Java
extension (".class"?), then you could much more easily
run Java code as CGI programs.

Of course...you'd still need an easy way to get the
environment variables.  The first bit of Java code that
I wrote (and about the last) was an interface to some
simple 'C' code to get environment variables.  I know;
it's bad style, but it worked well.  (The Better
Solution would be to send the data from the Apache
module in execl().)

Of course, if you're using something that much, you
should probably just compile it.

on decent operating systems you can run Java from the command line.
it's a compile time option on newer Linux kernels, so you might want
to recompile.

now I just wonder why anyone would want to use Java for CGI.  perhaps
it is due to some misguided idea that it's more portable? maybe it is
due to the fact that it's OO and you know as well as I do that OO
_always_ provokes a drooling-response in some people (the ones with
ties).

Perl is still the server-side-language of the web.  because has
everything Java doesn't have.  including portability.

I am more likely to use Emacs in batch-mode and program CGI in Emacs
Lisp than to use Java.

personally I prefer to use PHP/FI for server-side stuff.  if
performance is very critical; I write a module or I extend PHP/FI.

The similarity also occured to me.  But I see this as a very positive
reflection on the UCSD p-system rather than a negative one on java.
The p-system was very well designed.  It was just fif* years ahead
of its time.  Now that we have much faster CPU's and much more memory
this kind of portability makes a lot of sense.
