[fedora-java] Packaging tomcat shell scripts

[Dridi Boukelmoune]

I've installed tomcat 7 on my machine to take a quick look at how it's packaged:
- exploded FHS-compliant layout
- systemd-friendly equivalent to catalina.sh
- default configuration in /etc

Now if you want to run a tomcat instance (by instance I mean
$CATALINA_BASE) /usr/sbin/tomcat seems to be the best candidate.
Unlike catalina.sh, it expects a value for all the CATALINA_* variables
in its environment, while catalina.sh has fall-backs relative to
$CATALINA_HOME. Simply using /usr/sbin/tomcat as a substitute to
catalina.sh wouldn't work of course.

Could you please post an example of what maven produces ? This would
help see what could be done with simple maven configuration (eg.
-Dsystem=properties) and what would require a patch (and help estimate
the amount of work).
