ERROR: log4j.appender.DEBUG

Hi, I thank you for your help with the following case:

Trying to enable the DEBUG level in rootCategory, like this:

log4j.rootCategory=INFO,CONSOLE,DEBUG

Uploading the tomcat 7 server produces the following error:

log4j:ERROR Could not find value for key log4j.appender.DEBUG

The configuration of the log4j.properties is as follows:

log4j.rootCategory=INFO,CONSOLE


log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
