Getting log4j:ERROR No appenders could be found for category

Am using log4j to log errors for my Java application. When i run the unix script I can the following error message:

log4j:ERROR No appenders could be found for category (classname).
log4j:ERROR Please initialize the log4j system properly.

I do have the log4j.jar included in my classpath..

What could be the problem?

Where do you have log4j.jar installed ? Which version ?

You must either configure the logging in your code, or better - use a file on the classpath. At a basic level, this could contain, for example:-


# Set root logger level and its appender.
# Valid levels are INFO, DEBUG, WARN, ERROR and FATAL

# Set logger level for all classes in my package structure
log4j.logger.<your top-level package>=INFO, Console

# Console is set to be a ConsoleAppender.

log4j.appender.Console.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

Hope this does the trick.
