No, it's not. But RHEL re-packages Tomcat and does weird things to it.

What is the value of $CATALINA_HOME? CATALINA_BASE?

Tomcat will look in CATALINA_BASE/conf and CATALINA_HOME/conf for
catalina.properties. If CATALINA_HOME is set to /etc/tomcat6, then
Tomcat is going to try to look in /etc/tomcat6/conf. Does that exist?

If not, then you'll have to copy catalina.properties into your
CATALINA_BASE/conf.

I'm not sure how RHEL expects you to do things, and I'm not familiar
enough with the layout to comment on why it does or does not work.

If you want to know why it doesn't work on RHEL, you'll have to ask
the RHEL packagers... the stock Tomcat distribution works without any
problems.
