    log4j with jboss issue ?

    Jasdeep Newbie

      I tried to use log4j with my web application deployed on JBoss..
      but JBoss did not permit it . so i configured JBoss logging in my application as in this link :http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigureLogging...

      Every thing worked fine , but now i want to use MDC( mapped diagnostic context ) technique of log4j in my application .. which is not permitted in JBoss logging..

      So to configure log4j loging support i did following :
      1.Renamed log4j.xml in JBOSS_HOME/server/default/conf to jboss-log4j.xml
      2.Changed jboss-service.xml in JBOSS_HOME/server/default/conf accordingly to tell JBoss to use jboss-log4j.xml
      3. Added following code jboss-web.xml

      <class-loading java2ClassLoadingCompliance="false">

      4. added my own log4j.xml in WEB-INF directory for my application...
      Every thing else works fine but is not my application logs are not being generated ...

      The following exception is generated :
      13:26:43,234 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
      13:26:43,235 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by

      13:26:43,236 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".
