I am running under Solaris. If Tomcat isn't using any of the <1024 ports (i.e. listening to 80), then there's no reason for it to run as root. And if there's no reason for it to be root, don't let it be root. > I also wonder how you make sure Tomcat is completed started before > starting apache.

The problem, of course, is that your application and URLs won't work (and you'll get ugly errors). But, Apache will start fine and the connector will still work. You can try writing a small script that pings Tomcat on one of its "internal" ports and wait until a URL request comes back positive, and then have it fire off Apache. Or you can have your Tomcat create a "i'm alive" file using a method in a load-on-startup servlet, and your script can listen/watch for that file. Just make sure to remove it after you "see" it, so that you'll wait next time. It would be nice if there were some documentation on the Tomcat "admin" ports that are use to start and stop Tomcat (may in the source code, I haven't looked). Then you can use those to monitor the status of Tomcat. All sorts of contrived ways you can go here.
