Subject Re: Tomcat classpath not set at boot
Date Mon, 16 Jun 2003 00:17:36 GMT
I've done some more testing and it doesn't have anything to do with
starting Tomcat at boot as I first thought.  The problem is that my
servlet tries to connect to the X server when run.  I have no idea why it
needs to connect to the X server (It's a servlet that EspressReport wrote
to connect to a database and generate a report.), but anyway this seems to
be the problem.  In order to get my servlet to work I need to do 'xhost +
localhost' before Tomcat is started.  I'm starting Tomcat as root and root
is not allowed to connect to screen :0 by default since my user name owns
it.

I think if I started Tomcat with my user name and not root it would work,
however, for some reason I can't start Tomcat this way.  When I start
Tomcat as a normal user it starts fine and ps -ef shows the java processes
started by Tomcat, but after about 3 seconds all the processes quit and
Tomcat is no longer running.  Anyone have any idea why this would happen?
As root Tomcat continues to run.
