I think that this highlights a couple of issues:

1) The long term future of the sun jre/jdk in Debian - if and when it
gets removed from non-free then quite a few of those paths are going
to be obsolete.

2) The fact that none of the tomcat7 packages actually depend on a
java runtime environment - it actually gets pulled in by
libcommons-dbcp-java which is not right (can't believe I've not
noticed that before...)

I think we should introduce a dependency on default-jre-headless |
java-5-runtime | java-6-runtime in tomcat7-common and switch to using
/usr/lib/jvm/default-java.  That way we are saying that this is the
supported/tested jre from Debian.

If someone wants to download a different JRE/JDK from Oracle thats
fine - and we should let them set an appropriate JAVA_HOME through
/etc/default/tomcat7 is they want to go down this route - it looks
like this is already supported in the package and overrides JDK_DIRS.

The above also applies to the tomcat6 package.

Cheers

James
