Re: WO Apps do not restart automatically after one server upgrade...

Hello,

I had the same problem after I upgraded one of our xserve from 10.3.9  
to 10.4.6

It seems that something strange happens between restart of the  
computer to the defined host. On my computer the symptom was that the  
ethernet adresse for the specified domain name changed between restart.

I also traced a problem to the WOAdaptor not being able to connect to  
http://localhost:1085/ to get the configuration for the server.

What I have done to solve the problem was to change my configuration  
in the following way :

1/ Update the Adaptor configuration file located in :
	/System/Library/WebObjects/Adaptors/Apache/apache.conf
by changing the WebObjectsConfig line from http://localhost:1085 to  
http://1.2.3.4:1085  using the real IP of the computer
	This problem was detected by logging the WOAdaptor comportement. To  
start the log do :
sudo touch /tmp/logWebObjects
	after that it's possible to look at the WebObjects.log in /tmp/

2/ In System/Library/LaunchDaemons/ on :
	com.apple.womonitor.plist and com.apple.wotaskd.plist
I have added a new Parameter -WOHost=1.2.3.4 using the same IP than  
in the apache.conf file

3/ when I created my host in JavaMonitor I've done it with the same  
IP than above

4/ When I created an Application I've added the -WOHost=1.2.3.4 in  
the "Additional Arguments" textarea for the "New Instance Defaults"  
for the Application

I hope that this informations can help you to solve your problem
