Working dir incorrect tomcat 9.10?
Hi!
I'm in the process of upgrading from tomcat 8 to 9 and was running into a
probelm with velocity not beeing able to create the default log file,
./velocity.log and after some troubleshooting it seems it is trying to
create it in the root of the file system instead of the current working
directory, which i thought would be CATALINA_BASE.
I just did some test and logging in the webapp:
log.info("Working path: " + new File(".").getAbsolutePath());
would report "Working path: /.
And I could do a workaround by creating /velocity.log manually and give the
tomcat9 user ownership.
From the logs it seems that tomcat is picking up the correct settings, see
below, so I really cant get my head around it..
This has been workign without a problem from tomcat6 to tomcat8, is there
some configuration change I may have missed?

Re: Working dir incorrect tomcat 9.10?
Posted by Carl-Henrik Tjärnlund <ka...@gmail.com>.
Ok, thanks for the clarification and of course there are multiple ways
to solve this; I just ran in to problems since the behaviour seemed to
have changed between the versions but I've upgrade the whole stack
from OS to java to tomcat so its was hard to isolate the change and I
made the wrong assumption that the CWD was set to CATALINA_BASE. With
your information I got to the root of why the CWD has changed to '/'
and it was a simple as I had not set a home dir for the tomcat9 user
and thus the user-dir was automatically set to '/' when the
systemd-script started tomcat as the tomcat9 user..
Br,
Kalle

Or put -Duser.dir=[whatever] in CATALINA_BASE/bin/setenv.sh

+1
Moreover, Tomcat does not alter the CWD from whatever process launched i
t.

This would be best. Relying on the CWD is a bad practice that will
lead to these kinds of problems.

Or you could do System.getProperty("user.dir").
Tomcat does not care what the current working directory is when you
launch it. All it cares is the value of system properties
"catalina.home" and "catalina.base".
(The well known environment variables CATALINA_HOME, CATALINA_BASE are
used by catalina.sh/catalina.bat scripts to set those system
properties when launching Java process for Tomcat).
If your logging configuration supports substitution of environment
variables, use one of those variables explicitly, e.g. as
"${catalina.base}/logs" (see the default conf/logging.properties in
Tomcat for an example).

Konstantin Kolinko
