Not so fast on this.  While the host was successfully added, and the application seemed to be successfully added using JavaMonitor, the app itself is not being served up.  I get a No instance available error.

Did you check that your app instances not just start but also stop using JavaMonitor?

Once strange thing I noticed is the link under Name in the JavaMonitor Applications tab links to a .local address.  i.e. the host I have successfully added is www.netbrackets.com, but the link used for the added application is http://netbrackets.local/cgi-bin/WebObjects/netBrackets.woa/1 instead of http://www.netbrackets.com/cgi-bin/WebObjects/netBrackets.woa/1

In JavaMonitor, under the Site tab, make sure the HTTP Adaptor URL's hostname matches that of your real host name.
Should probably look like this:

http://www.netbrackets.com/cgi-bin/WebObjects

Also check the WebObjectsConfig value in the apache.con file in /System/Library/WebObjects/Adaptors/Apache2.2.
Probably something like:

WebObjectsConfig http://211.157.25.168:1085 10

While I don't have an /etc/WebObjects directory, I did try adding the line to my Application's Properties file and restarting, and it worked!

So the basic steps for me to change from localhost host to a domain name host:

1. Change the WOHost parameter in /Library/WebObjects/JavaApplications/wotaskd.woa/Contents/Resources/Properties file from localhost to my domain name
2. Add er.extensions.WOHostUtilities.localhostips=(IPAddress) to Application Properties file.
3. Delete the localhost host from 
4. Restart the machine
5. Add new host in javamonitor using domain name instead of localhost
6. Add application back inito javamonitor under the new host, and Add -WOHost <domainname> (e.g. www.netbrackets.com) to the Additional Arguments 
7. Start application

Now on to trying to add an application from a different host machine...

Thanks!

Did you set WOHost on wotaskd too?  And the application?  Did you try using WOHostUtilities?

Do what Chuck says. :-)
On hosts that have multiple IP addresses I have this in /etc/WebObjects/Properties

er.extensions.WOHostUtilities.localhostips=(10.0.0.105,211.157.25.168)

This will make the WO apps listen to all the give IP addresses. Try it with one address.  
All the WO apps will read this file, monitor and wotaskd and your app.

OK, I tried it on a machine with a domain name, and still no go  JavaMonitor did add the host, and showed the right reverse DNS IP address, but this time it says it can't contact the host-1085.  I did try rebooting the machine but no love.  I also went back and tried with a localhost host again, and that still works fine.

I don;t know if you will have much luck with that.  IIRC, it does not play nice with .local names.  Take a look at WOHostUtilities.  That might be what you need.

I don't think so, it's just the straight up IP address on my local network.  There is no domain currently mapped to the machine, I'm just doing some internal testing with it right now.  It does have a local name that mac os networking assigns to it (lionserver.local).

Is that the canonical IP for this machine?  Can it be resolved to the machine vs reverse DNS?

Hi All,
  I'm trying to change the host specified in WOMonitor from localhost to the IP of my machine, so that I can eventually manage multiple load balanced applications on multiple machines from a single WOMonitor.

To do this, I deleted the localhost host from WOmonitor and added a host by specifying the local IP of the machine (192.168.11.200).  I also changed the WOHost entry in the /Library/WebObjects/JavaApplications/wotaskd.woa/Contents/Resources/Properties
file from localhost to the local ip.  I then re-add my application back into WOMonitor, and restart the machine just to start fresh.

However, when I try to start the application, JavaMonitor doesn't seem to be able to start it.  The only log message I see is in the womonitor.log file:

Exception sending lifebeat to wotaskd: java.net.ConnectException: Connection refused

What piece of hocus pocus am I missing to be able to start using something other than localhost as my Host?

Thanks,
Jeff
