Re: JSVC, Redhat 8, and TomCat 5.0.xx startup
So its behavior is expected when launched manually as a non-root user, and when launched manually as a root user. That leaves the launch at boot time from init.d with unexpected behavior - is the boot script not being launched under root authority? Or is there a known corrective action?

Step-by-step: 1/ The boot script is called by root. 2/ Root runs jsvc, which calls the port (or whatever) with root privs. 3/ Root then calls setuid() et al under the covers to switch IDs to the Tomcat user. 4/ Tomcat (or whatever daemon) is run as the specified user. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JSVC, Redhat 8, and TomCat 5.0.xx startup
Hold on, I got another look at your first message: if the init script (run as root) fails, but jsvc works when called by root on the commandline, you most likely have an error in your init script. Most init script problems I've seen are based on assumptions about the (minimal) boot-time environment. e.g. look for environment variables that are set by root's .profile and such, because that file isn't sourced in for init scripts at boot time. If you're still stuck, post the script and I'll take a look at it. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JSVC, Redhat 8, and TomCat 5.0.xx startup
I have noticed that a number of other people have written with this problem, and I was wondering if there was a permanent solution yet. When using jsvc to srart the Tomcat server with its own user ID, launched from a shell script in init.d during startup, jsvc aborts. If, on the other hand, I launch the exact same script while logged in a root, the daemon launches correctly and stays in memory. Finally, if I log in as tomcat, it fails with exactly the same results as if it were launched during startup. Not being a linux guru (yet) or a jsvc guru, I am guessing. It appears to me as though the version of jsvc shipped with tomcat is attempting to write the jsvc.pid file somewhere that it lacks the authority to do so during the boot process. My reading of the symptoms could be wrong, so I would like some feedback from those who are really knowledgable about these products. Is there a solution to this problem? Thanks in advance.
