I just noticed that you said you have setenv.sh set to
CLASSPATH=“$CATALINA_HOME/lib/*”
That will find the jars but it won’t find your configuration file. You need to
specify
CLASSPATH=“$CATALINA_HOME/lib/*:${CATALINA_HOME}/lib”
Note that lib is specified twice, once with “/*” after it and once with nothing.
