Tomcat and commons logging
Can someone just PLEASE post a simple straight forward example of how to configure a Tomcat system (4.1.x) for once and for all without getting that damn No logger for class xxx exception. *sigh* I want no loggers defined for 3rd party packages (eg the host of jars required for struts 1.1). Well, default loggers that maybe just do nothing would be fine. Where how do I set this? __ Do you Yahoo!? Get better spam protection with Yahoo!

RE: Tomcat and commons logging
Normally this can be solved by add log4j.jar to your classpath. Are you sure it's an exception, not a warning? -Original Message- From: Riaan Oberholzer [mailto:[EMAIL PROTECTED] Sent: Friday, February 27, 2004 5:52 AM To: [EMAIL PROTECTED] Subject: Tomcat and commons logging Can someone just PLEASE post a simple straight forward example of how to configure a Tomcat system (4.1.x) for once and for all without getting that damn No logger for class xxx exception. *sigh* I want no loggers defined for 3rd party packages (eg the host of jars required for struts 1.1).

RE: Log4J and tomcat using Commons logging
Howdy, Is there a way to tell log4j to use the properties file without relying on the class loader, like an environment variable or something? That might make it easier to use. PropertyConfigurator.configure(getServletContext().getResource(/WEB-INF /config/log4j.properties)); would do the trick. Can also be done as a -D runtime parameter, set in JAVA_OPTS for tomcat. I agree with your assessment of the classloader problem, by the way, as it relates to commons-logging.

RE: Log4J and tomcat using Commons logging
Hi Larry, In my myapp/WEB-INF/lib I have: log4j-1.2.6.jar In myapp/WEB-INF/classes I have: log4j.properties In common/lib I have: commons-logging-api.jar commons-logging.jar log4j-1.2.6.jar And in server/lib I have no logging files. I intend to use log4j anyway so it is not a major problem if I use it directly rather than through commons-logging.

I am most curious about where all the jar files are - common/lib, shared/lib, or WEB-INF/lib? Probably the best info would be directory listings of common/lib, shared/lib, and WEB-INF/lib. I suspect that log4j is being loaded to far up the classloader tree to be able to find your configuration file when used through commons-logging, but when you use it directly, it is loaded again by another classloader that is able to find your configuration file. That is why I was asking if there was a way to tell log4j to use the properties file without relying on the class loader. I do not use log4j, so I do not know what it can do.

If I log directly to log4j it uses my log4j.properties file but if I use commons-logging it uses the default. For the moment I will stick to calling log4j directly.

RE: Log4J and tomcat using Commons logging
Hey Jim, I think Yoav's answer is very practical, and in spite of the fact that it would require a code change if you change loggers down the road, it is only a few lines in one place. You should think about it, because it is pretty low-cost, compared to the amount of time we have already spent. ;-) However, in the interest of understanding what is going on, I think what is happening is that the common classloader is loading commons-logging and log4j and looking for configuration there. It cannot find it because at that point, it does not know where to look - the configuration is at a lower level and is not available to the common classloader. Then when you try to use commons logging in myapp, it is not found in the myapp classloader, so it looks up to the common classloader and uses that one with the configuration found there. I would try adding commons-logging.jar to your WEB-INF/lib directory. That way, when the server wants to log, it should be able to. When your app wants to log, it should find commons logging and log4j right there and log4j should find the config there too. I will keep my fingers crossed. ;-) Larry [EMAIL PROTECTED] 02/17/03 02:08 AM Hi Larry, In my myapp/WEB-INF/lib I have: log4j-1.2.6.jar In myapp/WEB-INF/classes I have: log4j.properties In common/lib I have: commons-logging-api.jar commons-logging.jar log4j-1.2.6.jar And in server/lib I have no logging files.

RE: Log4J and tomcat using Commons logging
Hi Larry, Thanks for your help on this. I did have commons-logging.jar in myapp/WEB-INF/lib and also in server/lib but I had to move them because this was causing Tomcat to crash. I have found an email from Remy where he states it is a Tomcat classloader problem which will not be fixed until Tomcat 5. In the meantime I will stich to logging to log4j directly. Thanks again.

It was in server/lib but this causes intermittent problems that causes Tomcat to crash. I have posted this problem to this mail list and the same problem has been published on other mail lists. The fix is to move commons-logging.jar from server/lib to common/lib and not to deploy commons-logging with your webapp. At the moment I have commons-logging.jar only in common/lib and the log4j jar file in common/lib and my apps WEB-INF/lib dir. If I log directly to log4j it uses my log4j.properties file but if I use commons-logging it uses the default. For the moment I will stick to calling log4j directly. It would be nice to clear this up though as a lot of other people are having the same problem trying to use commons-logging.

RE: Log4J and tomcat using Commons logging
Hey Jim, Can you help me understand your configuration so I can help identify where the breakdown is? I am most curious about where all the jar files are - common/lib, shared/lib, or WEB-INF/lib? Probably the best info would be directory listings of common/lib, shared/lib, and WEB-INF/lib. I suspect that log4j is being loaded to far up the classloader tree to be able to find your configuration file when used through commons-logging, but when you use it directly, it is loaded again by another classloader that is able to find your configuration file. That is why I was asking if there was a way to tell log4j to use the properties file without relying on the class loader. I do not use log4j, so I do not know what it can do. Larry [EMAIL PROTECTED] 02/14/03 10:38 AM Hi Larry, I am not having a problem with log4j I deploy the log4j.properties to myapp/WEB-INF/classes and it works fine.

RE: Log4J and tomcat using Commons logging
If you are sure the logging API you are using is everything you will ever want or need, then you should not switch. If you think there is a possibility that you will ever want to use a different implementation, you shoudl think about switching. We have switched implementations three times since going with commons-logging, but have never needed to change a line of application code - all we have done is reconfigured the commons logging component. The applications still use the same interface, only the underlying implementation has changed.
