Sorry, Chuck I simply forgot to post the most vital information
with my query.

Both hosts run Tomcat with the HP-UX port of Java 1.4
as can be seen from the proc table's entry for the Tomcat server
process

# UNIX95=3D ps -x -C java -o args
COMMAND
/opt/java1.4/bin/PA_RISC2.0/java -Xverbosegc:file=3D/tmp/gc.out
-Xms1280m -Xmx1280m -Xmn786m -XX:+DisableExplicitGC
-XdoCloseWithReadPending
-Djava.security.policy=3D=3D/opt/hpapache2/tomcat/bin/../conf/tomcat.
policy -Dtomcat.home=3D/opt/hpapache2/tomcat/bin/..
org.apache.tomcat.startup.Main start


The Tomcat release to guess is a bit harder,
because the HP-UX depot that bundled Apache httpd and Tomcat
didn't come with the handy version.sh wrapper.
See it doesn't understand "version" in this incarnation


# export JAVA_HOME=3D/opt/java1.4
CATALINA_HOME=3D/opt/hpapache2/tomcat               =20

# $CATALINA_HOME/bin/catalina.sh version
Using CATALINA_BASE:   /opt/hpapache2/tomcat
Using CATALINA_HOME:   /opt/hpapache2/tomcat
Using CATALINA_TMPDIR: /opt/hpapache2/tomcat/temp
Using JAVA_HOME:       /opt/java1.4
Usage: catalina.sh ( commands ... )
commands:
  debug             Start Catalina in a debugger
  debug -security   Debug Catalina with a security manager
  embedded          Start Catalina in embedded mode
  jpda start        Start Catalina under JPDA debugger
  run               Start Catalina in the current window
  run -security     Start in the current window with security
manager
  start             Start Catalina in a separate window
  start -security   Start in a separate window with security
manager
  stop              Stop Catalina


There seems to be only a version.txt for Ant in the Tomcat libs,
but maybe you can guess by looking at these lines?


# find $PWD -name \*.jar|xargs -n1 $JAVA_HOME/bin/jar -tf |egrep
-i version\|release       =20

Honestly, I would like to
but if I were required to read all the docs=20
(let alone specifications and RFCs which mainly address software
implementors)
of all the services that run on the many servers I have to
administer
there wouldn't be much time left for anything else
(and this doesn't yet include comprehending their contents)
