Can't load log handler *.FileHandler

Starting Tomcat (installed from binary http://tomcat.apache.org/download-60.cgi, on a CentOS 5.5 server), I was getting an error like this in ''catalina.out''

Can't load log handler "4host-manager.org.apache.juli.FileHandler"


This was because I set ''JAVA_OPTS'' at the end of the startup script ''catalina.sh'', overwriting all the default ''JAVA_OPTS''...

So the solution is (obviously):

JAVA_OPTS="blablabla $JAVA_OPTS"
