[jboss-user] [Beginners Corner] - Classloader problem with log4j

Hi, I want to have my own log4j.xml in my application. Therefore I implemented a RepositorySelector as suggested in the JBoss documentation. But on startup I get following error: java.lang.NoSuchMethodError: org.apache.log4j.spi.RootCategory.(Lorg/apache/log4j/Priority;)V at com.soultec.trueAct.logger.AppRepositorySelector.init(AppRepositorySelector.java:47) at com.soultec.trueAct.listener.ContextListener.contextInitialized(ContextListener.java in the <JBOSS_HOME>/server/defautl/lib folder, there is the log4j-1.2.13.jar. But it seems, that the JBoss uses the log4j-boot.jar from the <JBOSS_HOME>/lib folder. Here is the structure of my ear-file: MyApp.ear + MyApp.war + META-INF + myjar.jar The RepositorySelector is initialized in a ServletContextListener which is in myjar.jar. In my application.xml i have an entry <module><java>myjar.jar</java></module> Please can somebody help me ? Here is the output of the jmx-console: org.apache.log4j.spi.RootCategory Information Repository cache version: org.apache.log4j.spi.RootCategory(1506dc4).ClassLoader=org.jboss.system.server.NoAnnotationURLClassLoader@10f6d3 ..org.jboss.system.server.NoAnnotationURLClassLoader@10f6d3 ..sun.misc.Launcher$AppClassLoader@a39137 ....file:/C:/Java/jdk1.5.0_09/lib/tools.jar ....file:/C:/Java/jboss-4.0.5.GA/bin/run.jar ..sun.misc.Launcher$ExtClassLoader@92e78c ....file:/C:/Java/jdk1.5.0_09/jre/lib/ext/dnsns.jar ....file:/C:/Java/jdk1.5.0_09/jre/lib/ext/localedata.jar ....file:/C:/Java/jdk1.5.0_09/jre/lib/ext/sunjce_provider.jar ....file:/C:/Java/jdk1.5.0_09/jre/lib/ext/sunpkcs11.jar ++++CodeSource: (file:/C:/Java/jboss-4.0.5.GA/lib/log4j-boot.jar ) Implemented Interfaces: ### Instance0 found in UCL: org.jboss.mx.loading.UnifiedClassLoader3@2c9103{ url=null ,addedOrder=2} ### Instance1 via UCL: org.jboss.system.server.NoAnnotationURLClassLoader@10f6d3 Regards Reinhard View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4051263#...
