The /var/run/tomcat.pid file is for tomcat to tell *you* what its
PID is. You cannot assign predetermined PIDs, but sometimes you need
to know the PID of a server process (to send it a signal, for
example). Many different servers write a /var/run/<servername>.pid
file when they start, so that scripts can get at the process ID.

No. Again, the tomcat process (whatever it is, I've never heard
of it before) will create the file if it doesn't exist, and
should delete it when it exists. If the lock file *does* exist
when the server starts, it shold refuse to run, since the
existence of the lockfile indicates that another instance
of the server is already running.
