Hi, there: Just follow up my previous email. If I unzip Jetty4.2.24-all package, after deploying my webapplications on its webapps directory, I did see everything is logged in logs\log4jetty.log, which means it takes extra\plus\resources\log4j.xml as log4j.configuration. However, if I unzip Jetty4.2.24.tar, and just copied the same log4j.xml and log4j.jar to ext\ directory, and run jetty as: Java -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger -Dlog4j.configuration=log4j.xml -jar start.jar etc\jetty.xml Jetty gives me warning as: log4j:WARN No appenders could be found for logger (com.xyz.myproject.web.Main). log4j:WARN Please initialize the log4j system properly. And no log file is created, nothing is logged correctly. Highly appreciated if anyone can help me on that issue. Thanks a lot in advance. David -----Original Message----- From: jet...@li...

I followed what you said: a. moved log4j.xml to ext directory; b. run jetty as: java -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger -Dlog4j.configuration=log4j.xml -jar start.jar etc\jetty.xml However, I still got that problem: > log4j:WARN No appenders could be found for logger > (com.xyz.myproject.web.Main). > log4j:WARN Please initialize the log4j system properly. And the log file is not even created. Is there any problem in my log4j.xml? Thanks a lot David -----Original Message----- From: jet...@li...

Subject: [jetty-discuss] Re: How to get log4j work in Jetty4.2.24 David, AFAIK, you have to tell log4j where to find it's configuration file. So you have to use something like: -Dlog4j.configuration=log4j.xml Where log4j.xml has to be on the classpath, by which I mean the same classpath as the log4j.jar. So try copying the log4j.xml file into the /ext directory. regards Jan David Chen wrote: > Hi, there: > > After using Jetty4.2.24, we have some issues on log4j.
