Hi,

If log is not null(log: org.apache.commons.logging.impl.Log4JLogger@11e67ac), but I don't see any log info in console.        
    ...
...  
               Log log = LogFactory.getLog(target.getClass());
               System.out.println("log: " + log);
               log.trace("Executing method: " + method.getName() + " " + target.getClass());
               log.info("Executing method: " + method.getName() + " " + target.getClass());
...
...

What am I doing wrong?

thx

Try

Log log = LogFactory.getLog("STDOUT");

What's your config file called and where is it? Do you get any errors reported in the console?

</log4j:configuration>


OR

just create a new log4j.properties and put in this :

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{DATE} - %p %c - %m%n

log4j.rootLogger=DEBUG, CONSOLE

You can also get the logger as :

Logger logger = Logger.getLogger("your.log.name.here");

If the logger is found, it will take the specific logger, or just use the root logger
