FileAppender object is not assignable to a org.apache.log4j.

[cwele]

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/
 ......

Is there any solution for this problem ? Thanks in advance...

Do you have log4j.jar packaged in your application? If so, remove it.
