Oh, I remember it was about invoking the startup script, and also one big
hassle was to shut down JServ from Apache, connecting to the port to issue a
shutdown command...

For the Domino connector I just do bin/tomcat.sh start or bin/tomcat.sh
stop appropriately. It seems to work OK and is very simple to implement.

Things improved ApacheJServ-1.1.2 works without problems on our BS2000 EBCDIC
mainframes.
The idea to have:
httpd <--> "watchdog process" <--> service <--> JVM with Tomcat
Sounds Ok for me.

Good that remains me that I have to patch mod_jserv, that "watchdog" process
holds the listen socket and it should not. (That does "Address already in use"
making apachectl graceful when using mod_jserv).
That is the only problem I have with mod_jserv :-)
