    log4j problem with jBoss app server

    John Eric Hamacher Newbie

      Hello:

      I get the following errors when I start up jBoss (4.2.1.GA):
      -------------------------------------------------


      ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppend
      er" object is not assignable to a "org.apache.log4j.Appender" variable.

      ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".



      My jboss-log4j.xml file is as follows:
      -----------------------------------

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
      <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

       <appender-ref ref="FILE"/>
       </root>
      
      </log4j:configuration>



      ------------------------------------------------

      The log file for the HVGN appender is created but nothing is written to it when "duke" and descendant package class files issue log
      statements. In addition, despite the error with the FILE appender,
      content is still written to server.log. I don't see an error in my jboss-log4j.xml file. I tried to substitue in
      "jboss.logging.appender" for the class attributes in the appenders, but I get the same errors.

      Anybody got any ideas?
