When you run a single instance, does it also require the port number in the URL? Are you launching wo(e)taskd with - WOHost=localhost as well?

Thanks for all your help Chuck,

Yes, it does require the port number in the URL.

Then it is not going through wotaskd normally.


Regarding the launch of wotaskd, JavaMonitor and Wotaskd were set to launch on system startup by removing #s in a configuration file (we're running MacOSXServer10.3.9), we do everything in JavaMonitor. We also added the WOConfig.xml file with instances specs. I'm not sure if I'm actually launching wotaskd with - WOHost=localhost, but I did include it in the only place I know in JavaMonitor, the Additional Arguments in the Application settings where we also set the password.

Perhaps this is our problem... How does one set -WOHost=localhost on wotaskd launch (is there a way to configure it on system startup)? Does it require the command-line in Terminal?

You can set this in a few different ways.  One is to edit the file
/System/Library/StartupItems/WebObjects/WebObjects

And add it to the wotaskd line like this
"$WOSERVICE" -appPath "$WOTASKD" -WOHost localhost >/var/log/ webobjects.log 2>&1 &

Another is to edit
/System/Library/WebObjects/JavaApplications/wotaskd.woa/Contents/ Resources/Properties

And add
-WOHost localhost

Wotaskd (or the machine :-) needs to be restarted after  you do this.


Once we deploy on our public server (with a real host address, not localhost), I guess there won't be any need to specify WOHost, will there?

Not if that name is the default name for that server. If there are multiple names that resolve to the same machine, then you might.


With our current experience and all, we don't want to try it on our public server, so there's no way for us of knowing if the problem is actually making it work on a localhost or making it work at all... We know it's probably just one little thing in our config, we just can't seem to pinpoint it.

See if the above works.  Also you can try

sudo touch /tmp/logWebObjects
and then look at
/tmp/WebObjects.log
to see if the woadaptor has anything useful to say on the matter.

Ok, we've read about 500 pages of troubleshooting, configured and re-configured apache.conf, WOConfig.xml, all setting in JavaMonitor and we just can't get multiple instances to work at all (they start up alright and work individually, but that's it)! We have to specify each instance's port in the URL to get each instance to work, connecting to the .woa file without specifying a port returns an error stating nothing is there. Round-Robin load balancing, with our WOConfig.xml file and apache.conf modifications (religiously followed in Apple's Deploying_Applications" guide), should be doing its job, it just doesn't work.

We have a lot of experience running a single instance of a .woa in JavaMonitor, but we recently got so much traffic we need multiple instances.

We are trying to configure a multiple instances set-up with Round- Robin load balancing on a local network (at first, until we get the hang of it and can actually find the courage to configure our Xserve to do so). We are running Mac OS X Server 10.3.9 on a dual G4 tower, connected to a router.

We configured its Host to localhost, as well as all settings required. Our main reference tool is Apple's "Deploying_Applications" guide, which seems really complete.

Our URL to Adaptor is http://localhost/cgi-bin/WebObjects/

We are REALLY desperate and need this thing up and running ASAP. If anyone knows what we are doing wrong, any suggestion would be greatly appreciated! I followed the "What's My URL" thread from Jeffrey Schmitz. Chuck Hill got him up and running; we seem to have a very similar problem, except setting -WOHost localhost in the Additional Arguments section of New Instances Default settings didn't do the trick for us.

Thank you for any help/suggestions.
King Regards,
Pascal
