What you have to understand about chroot is that 100% of what you need
to launch your process needs to be available *inside* the chroot'd
environment.
So, if you need to chroot to /var/tomcat/chroot, then you are going to
need a directory at /var/tomcat/chroot/var/lib/tomcat7 containing
whatever files you expected to be there.
Have you had Tomcat working in a chroot'd environment in the past?
I've had a nightmare of a time trying to get a JVM to launch within a
chroot'd environment because it needs to many support libraries, etc.
available just to start. Once the JVM can launch within the chroot'd
environment, getting Tomcat to work should be trivial: just move
everything Tomcat needs into the chroot root-dir (likely a
subdirectory of this, actually) and you should be fine.
As for launching Tomcat within the chroot'd environment from a service
script, your service script needs to execute the "chroot" command and
then give a command to run once the chroot() system call has
completed. Presumably, that command will be
"/path/to/tomcat/bin/catalina.sh start". The /path/to/tomcat should be
relative to the chroot's root, and both CATALINA_BASE and
CATALINA_HOME should also be relative to the chroot's root directory.
Hope that helps,
