          the problem have some reason.
          i).if your aplication lib have the log4j.jar,del it.
          ii).your aplication use the log4j.properties, it's unusefull. you must instead a log4j.xml.
          you can get the file in Jboss's conf/log4j.xml, you can put a copy to your aplication path.

          that's all.

            I'm having exactly the same issue:

            09:53:59,242 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.

            However, if I remove Log4J from my build path, the application won't compile. I've tried several versions of Log4J, just in case, with no change in behavior. Been using JBoss for years, but with 4.0.5GA I'm having this problem with my applications.

            I've tried everything I can think of.

            MacOSX 10.4.8
            Java 1.5_06
            MyEclipseIDE 5.1.0GA
            Eclipse 3.2.1

            Any ideas?

              The objective would be to ensure that the log4.jar in your WEB-INF/lib is NOT there when you deploy to jboss, even though it is in your build path.
              Ant perhaps?

                My own logs used to get created when I had my log4j.jar and commons-logging in my WEB-INF/lib folder, but I used to get the "OnlyOnceErrorHandler" exception. So in order to eliminate this exception i removed the log4j and commons-logging from my WEB-INF/lib folder. I dont get any exception anymore. But now, my logs dont get created anywhere- not even in server.log
