Yes, the SiteConfig.xml is the same. Usually, I put the Wonder versions in /Library/WebObjects/JavaApplications (or /opt/Local/Library/WebObjects/JavaApplications if it's on Linux) and I change the startup scripts for wotaskd and JavaMonitor to use the Wonder versions. We are running the Wonder versions for months without any problems.
Interesting...that's sort of what I was looking for. Is it pretty straightforward to migrate from the standard JavaMonitor and wotaskd to the Project Wonder versions? We haven't been using them so far. Thanks very much for the help!

I've used monit in the past with Ruby on Rails and Java app servers, but not with WebObjects. I'm wondering if anyone else has setup something similar, and how you did it. Is there a way to invoke WOMonitor to start/stop the application from the command line, so I can call it from monit, or am I better off replacing WOMonitir with monit altogether and just maintaining the startup options in my monit configuration?
I don't think you need to replace JavaMonitor with monit, you just have to use monit to monitor your apps. I use Nagios to monitor our apps, but I don't see why it wouldn't work with Monitor.
Check the wiki for direct actions and REST calls you can call to monitor and restart your apps :
