Hi
I am new to Jboss. I was using iplanet prior to this. My web application is using log4j for logging. But how the log4j be configured with Jboss, I am not able to find out. I have tried by putting log4j.properties file in the WEB-INF/classes folder and the log4j jar file in WEB-INF/lib folder. But on running my web application it is not generating any log files, as configured by me in log4j.properties file. Instead it is showing exception in the "server.log" file.
The exception is 
2006-10-24 13:10:29,354 INFO  [STDOUT] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.
