RE: Could not instantiate appender named "console" Date Mon, 18 Oct 2010 14:15:48 GMT Hamed, I believe this is the key message for you: Could not find value for key log4j.appender.console You've configured an appender named "CONSOLE", but you haven't configured one named "console". Case matters. Change these three lines: log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=[%t:%p] %c: %m%n to this: log4j.appender.console=org.apache.log4j.ConsoleAppender log4j.appender.console.layout=org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern=[%t:%p] %c: %m%n and you should see better results.
