Hi, i can't configure log4j to work with JBoss 4.2.0. The same configuration works fine in my previous JBoss installation (3.2x). Here is the problem:
log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. log4j:ERROR The class "org.apache.log4j.Appender" was loaded by log4j:ERROR [WebappClassLoader delegate: false repositories: /WEB-INF/classes/ ......
Do you have log4j.jar packaged in your application? If so, remove it.
