Just create or edit CATALINA_HOME/bin/setenv.sh for Linux:

CLASSPATH=$CATALINA_HOME/bin/jul-to-slf4j-1.7.5.jar:\  
$CATALINA_HOME/bin/slf4j-api-1.7.5.jar

or CATALINA_HOME\bin\setenv.bat for Windows:

set CLASSPATH=%CATALINA_HOME%\bin\jul-to-slf4j-1.7.5.jar;^
%CATALINA_HOME%\bin\slf4j-api-1.7.5.jar
