Dear Tomcat Users, I have configured Tomcat to use log4j according to http://tomcat.apache.org/tomcat-7.0-doc/logging.html I have used the same log4j.properties. My web application is using log4j as well. There is no log4j.jar in WEB-INF/lib. I have found entries in the web application's root logger's appender's file, which was in the Tomcat's root logger's appender's file (${catalina.base}/logs/catalina.) when there was no webapp added. For example: 2012-09-16 11:19:57,132 INFO org.apache.catalina.startup.Catalina.start:652 - Server startup in 2028 ms Debugging of writing this entry the parent of Category org.apache.catalina.startup.Catalina seemed to be the web application's root logger. After googling on it, I have found, that the problem of "one application can steal others applications root logger" is known. I am using Windows7, Tomcat 7.0.26, log4j 1.2.9, and tried with Tomcat 7.0.30, log4j 1.2.17 as well and the result was the same. The web application's log4j.xml: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";> <appender name="MYAPPENDER" class="org.apache.log4j.FileAppender"> <param name="File" value="${catalina.base}/logs/myappendersfile.log" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %5p %c.%M:%L - %m%n" /> </layout> </appender> <root> <priority value="info" /> <appender-ref ref="MYAPPENDER" /> </root> </log4j:configuration> How can I prevent Tomcat from using the web application's root logger?
Thanks in advance, Izolda
