Hundreds of LogConfigurationException
Hi all, I am getting a large number of the following exceptions, until the server eventually stops responding. org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JCategoryLog does not implement Log at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:555) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:289) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:409) at org.apache.tomcat.util.log.CommonLogHandler.log(CommonLogHandler.java:97) at org.apache.tomcat.util.log.Log.log(Log.java:198) at org.apache.tomcat.util.log.Log.log(Log.java:192) at org.apache.tomcat.util.log.Log.log(Log.java:174) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:533) at java.lang.Thread.run(Thread.java:536) Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JCategoryLog does not implement Log at org.apache.commons.logging.impl.LogFactoryImpl.getLogConstructor(LogFactoryImpl.java:420) at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:548) ... 8 more Caused by: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JCategoryLog does not implement Log at org.apache.commons.logging.impl.LogFactoryImpl.getLogConstructor(LogFactoryImpl.java:416) ... 9 more I have log4j in WEB-INF/lib and commons-logging.jar in WEB-INF/lib and also in TOMCAT_HOME/server/lib.

RE: Hundreds of LogConfigurationException
Filip, Jim, Yoav thank you! I am using Tomcat 4.1.18 which has commons-logging.jar in server/lib *and* commons-logging-api.jar in common/lib. The jar files commons-logging.jar and commons-logging-api.jar seem to differ only in the absence of log4j support in the latter file. Placing both files as well log4j-1.2.8.jar in common/lib seems to be working as far as logging is concerned. (I also removed commons-logging.jar from my webapps WEB-INF/lib.) Eventually though, my tomcat server still dies a painful death but I can now see the error messages. :-) Why on earth are there two different jar files with almost identical content? At 12:33 19.02.2003 -0500, you wrote: Howdy, Ceki - it's kind of weird to see your name outside the log4j dev list ;) Cool though. Anyways, I think the issue here is with having multiple copies of commons-logging. Tomcat uses commons-logging and allows apps to use it as well by placing it common/lib. However, there's a classloading conflict. Other people have reported this, e.g. http://marc.theaimsgroup.com/?l=tomcat-userm=104305604609583w=2 Perhaps this is worth a shot: move commons-logging jar out of common/lib and into server/lib, so tomcat can still use it internally. Keep a copy of of commons-logging jar (and log4j jar) in your /WEB-INF/lib directory. Does that make the problem go away?

RE: Log4j-1.2.5
Lenny, What are the exact problems you are experiencing? What are you doing and what goes wrong? Have you tried putting log4j-X.X.jar under WEB-INF/lib of your webapp? Have you read the section Default Initialization under Tomcat in the log4j manual (http://jakarta.apache.org/log4j/docs/manual.html)? For those interested, I have a long gripe about commons-logging on the log4j-user mailing list: http://marc.theaimsgroup.com/?l=log4j-userm=102640868804904 but that's another story altogether. Let me rephrase my question: After some research through the Jakarta Commons Logging site, I've come to the conclusion that it is going to be very involved to set up Log4j-1.2.5 with Tomcat 4.1.3!!! If someone using Tomcat 4.1.* has already successfully set up and is using any \ versions of Log4j under Tomcat 4.1.* with along Commons Logging jars, would you \ please forward an example of how you set up to me. I've read just about everything I could find regarding log4j and commons logging and I still cannot figure out how to set them up to work together. Any resonse would be greatly appreciated. Please excuse the multiple posts, but I'm am really looking for a solution to this my \ problem. Thanks, Lenny Sorey ** Where exactly should the log4j-1.2.5.jar be located in order to get it to work within Tomcat 4.1.3? I can get log4j to work with log4j.properties while I run it as a separate servlet by starting it from a command line with java after I compile it the servlet alone. I still can't get it to work with Tomcat 4.1.3 My JSP's currently run find and retrieve data. I really need to place some log4j \ statement to debug in some servlets. Any help would certainly be appreciated. Oh Yeah, The folks from the Loggers4J Users group suggested that I asked this group \ for help regarding using log4j with Tomcat.

log4j in Tomcat 4.x
Hello, I would like to inquire about the status of log4j in Tomcat 4.x, more specifically in Catalina. I had heard through the grapevine that Catalina was going to use log4j internally. Is this correct? Thanks for any info on this matter. Ceki -- Ceki Glc Web: http://qos.ch email: [EMAIL PROTECTED] (preferred) [EMAIL PROTECTED] I hope to see you at my ApacheCon 2001 presentation entitled "Log4j, A Logging Package for Java". See http://ApacheCon.Com/2001/US/ for more details.
