Hi,
I think it is a good question.
I found it also confusing. I installed tomcat few minutes ago (after a while) and I notice they are two different "webapps" places.
at /usr/share/tomcat6/webapps/default_root/ at /var/lib/tomcat6/webapps/ROOT/
The content of both are the same but none of them are symlinks.
When I started tomcat it says:
Quote: This is the default Tomcat home page. It can be found on the local filesystem at: /var/lib/tomcat6/webapps/ROOT/index.html
Tomcat6 veterans might be pleased to learn that this system instance of Tomcat is installed with CATALINA_HOME in /usr/share/tomcat6 and CATALINA_BASE in /var/lib/tomcat6 So, based in this information, the /usr/share/... folder was kept for backward compatibility, right?
But according to what you posted libs are being read from the CATALINA_HOME instead of CATALINA_BASE.
Perhaps they still keep that default reference to prevent other systems to stop working after updating?
Good observation!
UPDATE:
I read this at: /usr/share/tomcat6/bin/catalina.sh : Quote:
CATALINA_HOME May point at your Catalina "build" directory.
#
CATALINA_BASE (Optional) Base directory for resolving dynamic portions
of a Catalina installation. If not present, resolves to
the same directory that CATALINA_HOME points to.
When we read at: /etc/init.d/tomcat6 :
(at the beginning)
CATALINA_HOME=/usr/share/$NAME
(then...)
Directory for per-instance configuration files and webapps
CATALINA_BASE=/var/lib/$NAME
However, If you try to start TOMCAT manually (as I did long time ago) with: sudo /usr/share/tomcat6/bin/startup.sh
It displays: Quote: Using CATALINA_BASE: /usr/share/tomcat6 Using CATALINA_HOME: /usr/share/tomcat6 Using CATALINA_TMPDIR: /usr/share/tomcat6/temp Using JRE_HOME: /usr touch: cannot touch `/usr/share/tomcat6/logs/catalina.out': No such file or directory /usr/share/tomcat6/bin/catalina.sh: 357: cannot create /usr/share/tomcat6/logs/catalina.out: Directory nonexistent So, why here CATALINA_BASE is set to the same as CATALINA_HOME?
/usr/share/tomcat6/logs/ do not exist, but exists in /var/lib/tomcat6/logs/
I see that my logs are writing into /var/lib/... when starting Tomcat from the init.d script. So its better starting it from there.
