Answer 1

You can do the following:

1. send the CATALINA_HOME as an environment variable using -D option. You just have to run

set JAVA_OPTS=%JAVA_OPTS% -DCATALINA_HOME=%CATALINA_HOME% if you are on windows or export JAVA_OPTS=${JAVA_OPTS} -DCATALINA_HOME=$CATALINA_HOME for unix.

Now just use ${CATALINA_HOME} into your log4j configuration file and this should work.
