+1 At least on CentOS Tomcat starts at run level 3, so you won't have an X server available. You could try the following, but again I don't know if you can enforce the order. As root, do the following: chkconfig --levels 34 tomcat6 off chkconfig --list tomcat6 You should only see tomcat6 start up on run level 5, which is multi-user plus X. Now, add the display variable (DISPLAY=localhost:0.0 or maybe DISPLAY=localhost.localdomain:0.0) to setenv.sh. This is provided that the Ubuntu scripts do the right thing and execute setenv.sh . . . I of course have no idea what happens when a person runs your web application remotely. I'm not sure that this will help, but at least it's a shot. /mde/ > 2.
