Assume you have TC7 installed and configured.1. put a any jar to your separate
local path, such as /home/foo/lib/food.jar2. edit
$CATALINA_HOME/conf/catalina.properties to apend "${foo.bar}/lib/food.jar" to
common.loader property3, setenv JAVA_OPTS -Dfoo.bar=/home/foo4. start TC7, then
stop TC7, you will see the warning complaining it could not find
$CATALINA_HOME/bin/${foo.bar}/lib/food.jar not found.
Of course, if in a deployed app where using any classes in food.jar is not
available for sure.
