As long as you've reposted this note of mine :-), I should take the
opportunity to correct myself.  It was actually ServletExec (from New
Atlanta) that I had used (with NES) before switching to Tomcat/Apache,
not JRun.  Don't know what I was thinking when I wrote that :-).

I had evaluated both ServletExec and JRun.  They seemed similar in
terms of functionality and performance.  I went with ServletExec
because it was easier to set up, and because their support was *much*
better.  They have a mailing list where the ServletExec/New Atlanta
people are *very* responsive.  This is running on AIX, FWIW.
