Log4j presentation at ApacheCon 2003
Here is a draft of my log4j presentation abstract for ApacheCon 2003. What is new in log4j version 1.3? = Log4j is a Java logging framework affiliated with the Apache Software foundation. By some estimations one million Java developers use log4j regularly, ranking it as one of the most popular Java projects of the ASF. Log4j version 1.3 (to be released) will bring many new useful enhancements. These include: - significant improvements in speed and memory management - spectacular enhancements to Chainsaw - highly extensible XML configuration files - support for custom conversion words in PatternLayout - a new logging dimension in the form of logging domains - plugins, receivers, and watchdogs... - interoperability with log4j-like logging frameworks in other languages - strategy based rollovers This will first quickly introduce log4j and proceed to discuss each of the aforementioned improvements in some detail.

Problems using Log4j on WebSphere 5.0 on Win2K
Hi, Sorry for the nagging, but does any one have a clue of what's happening here? -Original Message- From: Tarek M. Nabil Sent: Sunday, July 20, 2003 1:50 PM To: 'Log4J Users List' Subject: RE: Problems with WebSphere 5.0 on Win2K Thomas, Thank you very much for your reply. 1- The log4j jar is in the WEB-INF/lib directory of the war that I added to the ear using the application assembly tool of WebSphere. 2- No, it's not. I didn't know I had to do that! Do you think that's what causing the problem? Struts.jar works fine, although it's in the same place and not mentioned in in manifest files. 3- The log4j.properties is located in the WEB-INF/classes directory of the war.
