Log4j And Tomcat

Question

Hi,
I'm trying to get log4j to work with tomcat, but for some reason none of the logs get written to the logfile.
I have a logfile containing:
     <appender name="apachelog" class="org.apache.log4j.FileAppender">
          <param name="File" value="${catalina.home}/logs/junk.log"/>
          <layout class="org.apache.log4j.PatternLayout">
               <param name="ConversionPattern" value="%d %-5p (%F:%L) - %m%n"/>
          </layout>
     </appender>
     <logger name="org.apache.jk.common.ChannelSocket">
            <level value="info"/>
            <appender-ref ref="apachelog"/>
     </logger> 
...Except the tricky thing is that though I don't have access to the source code for this jk.common class, I'm getting a ton of "INFO" logs from it, and I don't want them showing up on the console.
I've tried adding a line logger = Logger.getLogger("org.apache.jk.common.ChannelSocket") in my classes, but that doesn't work. In fact, under tomcat, I can't even get logging working for my other classes!
The logfile is getting picked up by tomcat (If it isn't configured properly, tomcat gives me errors on startup). The specified log folder is empty, and the output still goes to the console.
Can someone please help?
Thanks.

It doesn't seem to work unless I actually call getLogger() & then call info manuallyI don't follow. What doesn't work? Your code always needs to call getLogger("somename") followed by logger.info("Some message"); in order to log an INFO message.
If only there was some way to associate a logger with a class during runtimeLogger's aren't directly associated with classes at all. Every logger has a name and by convension the name is the same as class that creates / uses it..
Logger.getLogger("com.somepackage.anotherpackage.MyClass");could be replaced with
Logger.getLogger("debugLogger");The reason for using the fully qualified class name is so that you can turn on/off logging by package or by class, e.g.
<logger name="com.somepackage">
    <priority value="OFF"/>
</logger>Turns off all logging for every logger with a name that starts with "com.somepackage". The fact that just happens to be a package name is irrelevant.
I appreciate your help so far, but I'm really stumped as to why1)Logging happens to the console instead of the logfile
2)It bypasses the logger.info() method somehow
Tomcat uses commons logging, which in most cases uses Log4J behind the scenes. Is it possible you've instead managed to enable the logging that comes with J2SE? Download the Tomcat source, put a break point at the line that reads log.info( "connection timeout reached"); and see where it takes you when you step through.
