It was back in 1997, and I remember several patches across 2 months from Ed
Korthof just to "make it work". But you should get back and see the
archives.

I remember it was a big pain in the ass (and that for Jserv 1.0 I  was
always starting Jserv stand alone!)

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 :-)

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...

I'll do some reading. Do you recall whether the problems where specific
to that implementation of the startup code or more generically related
to having the servlet container autostart?
