Tomcat6 error

Dear All,

We are getting the below error in catalina.out file. I using Tomcat6 with JDK1.6. But tomcat works fine and due to this warning message, size of catalina.out file is very high. Please suggest how to fix this Warning message.

WARNING: error instantiating '1catalina.org.apache.juli.FileHandler,' referenced by handlers, class not found
java.lang.ClassNotFoundException: 1catalina.org.apache.juli.FileHandler,
<<No stacktrace available>>

Your installation of JAVA and/or Tomcat seemed to be missing some library or maybe changing this:

before:

Code:

JAVA_HOME=/usr/java/latest
JRE_HOME=/usr/java/latest/jre

after:

Code:

JAVA_HOME=/usr/java/jdk1.6.0_16
JRE_HOME=/usr/java/jdk1.6.0_16/jre

Dear Robertjinx,

Thanks for the reply. Could you suggest a way to stop these warning messages as Tomcat works fine with these wanings also.

Drop the usage of "1catalina.org.apache.juli.FileHandler" from logging.properties:

Code:

logging.properties:handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
logging.properties:.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
logging.properties:1catalina.org.apache.juli.FileHandler.level = FINE
logging.properties:1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
logging.properties:1catalina.org.apache.juli.FileHandler.prefix = catalina.

Better idea would be to make sure you have all the libs and necessary files for tomcat to run properly. This option is way better then removing the lines from the logging configuration file.

I've tried to download Tomcat6 from apache.org, unpacked the tarball, set the java home, openjdk 1.6.0_24 (jre) on openSUSE 12.1 and works out of the box without any catalina error, which means you are something.
