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

[reinhard.graf]

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:
