Finally found a fix for this. By changing the port number Monitor
uses, I rebooted and Monitor successfully started my app. So in
summary, here's what happened, in case anyone else comes across
something similar:
Using Webobjects 5.3 deployment (and development) on Mac OS/X 10.4
My app was initially working fine, and Monitor would start it up
after every reboot automatically.
I had two power outages, and both times after the outage Monitor
wouldn't start my app anymore. No errors, it just hung when starting
up.
After the first outage, I didn't have time to mess with it so I just
re-installed the OS and everything else from scratch.
After the second outage, I played around and found that after each
reboot, if I deleted the host entry from Monitor and added it back
in, Monitor could then start my app. It still wouldn't start it on
a reboot of my machine though. And no, my IP wasn't changing between
reboots.
I then changed the default port that Monitor started with, and then
it started working 100% again, even on machine reboot.
Don't ask me why the error occurred in the first place, or why
changing the port number fixed things. If anyone thinks they know,
please post it.
Thanks for all your help,
Jeff

Thanks Chuck,
One other thing I've found is if I delete the Host entry and
then add it back in using Monitor, I can then start the app with
Monitor. Note I don't have to delete the Application, just the Host.
This still isn't an optimal work-around though since the app still
won't come up automatically on a re-boot of the machine. I have
to delete and re-add the host back in everytime I reboot, even on
a graceful reboot, but I thought perhaps it would give you or
someone else another clue.
Hi Jeff,
It sounds like the host name / IP is changing. What is in your
/Library/WebObjects/Configuration/SiteConfig.xml
in the <hostArray> tag? Are you using an IP address or a domain
name? Is the IP address on this machine static or set by DHCP?
Chuck
Thanks,
Jeff

The only thing that I can think of is that wotaskd is running
under a different user (appserver instead of root) and that the
appserver user lacks permissions on something (log directories,
app directories). Permissions problems will prevent the app from
launching.
On that version of WO/OS X, wotaskd should be running as
appserver. Perhaps you had killed it and started it manually as
root before the power outage? The reboot would have taken it back
to appserver.
My best guess at this time of morning.

Hello,
Using Webobjects 5.3 (develop and deploy on the same machine)
I've recently had two power failures and both times afterward,
Javamonitor could no longer start my app that it was starting
fine before the power failures. I can still run my app fine
from the command line, giving all the arguments that JavaMonitor
says it's going to use (I did have to put single quotes around
the () specified after the -NSProjectSearchPath option), but
when starting from Javamonitor, it says the app dies (and it
does). I wrote a script I found when searching the archives to
start the app so that a log file would be written during
startup, but no errors show up in the log file. When launching
from JavaMonitor, the logs stop after printing the Generated
classpat, i.e. it never prints the line about creating a
LifeBeatThread. My script looks as follows:
#!/bin/sh
/Library/WebObjects/Applications/MyApp.woa/MyApp $* > /tmp/
appLaunch.log 2>&1 &
Here again I can run this script from the command line with the
JavaMonitor noted arguments with no problems and the app runs
fine. The last time I had to reinstall my OS from scratch to
fix things, but I am hoping there is some easier way to fix
things. I have also tried deleting and reinstalling my app from
scratch but even that doesn't work. Yes, I know I should have a
UPS (it's on order), but I'm wondering what about a power down
would cause this problem?
btw, this problem sounds a lot like a problem Randall Perry had
in a thread that he started back in May 2004 and I'm wondering
if he ever got a resolution on that one.
Any help on this would be GREATLY appreciated as I've basically
hit a wall.
