how to use errorHandler

Hi,
    I getting following error while using the errorHandler. Request help in
proper usage of errorHandler.
-----------------------------------------------------------------------------------------
log4cxx: Could not instantiate class
[org.apache.log4j.varia.FallbackErrorHandler].
log4cxx: Class not found: org.apache.log4j.varia.FallbackErrorHandler
-----------------------------------------------------------------------------------------

Following is my configuration file

<?xml version="1.0" encoding="UTF-8" ?>
 <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
 
  
  <appender name="appxConsoleAppender"
class="org.apache.log4j.ConsoleAppender">  
    
    
        <layout class="org.apache.log4j.PatternLayout">
            
        </layout>
  </appender>

  
  
  <appender name="appxNormalAppender" class="org.apache.log4j.FileAppender">
    
    
    
    <layout class="org.apache.log4j.PatternLayout">
      
    </layout>

    <errorHandler class="org.apache.log4j.varia.FallbackErrorHandler">
      <root-ref/>
      <appender-ref ref="appxConsoleAppender"/>
    </errorHandler>

  </appender>

  <root>
        <priority value="TRACE" />
        <appender-ref ref="appxNormalAppender"/> 
  </root>

</log4j:configuration>

It looked correct to me, but you can compare with:

trunk\src\test\resources\input\xml\fallback1.xml

Mit freundlichen Grüßen,

    Thanks. I will check the details. Is my configuration file correct ?

Which version are you using? 0.10.0 has been released 2008-04-03, but
there were changes afterwards to fallbackerrorhandler.h and other
files regarding error handling afterwards. Additionally, there's a
test called errorhandlertestcase which seems to successfully use a
configuration with FallbackErrorHandler.

You could try using the current trunk codebase which builds and passes
the tests on most of the systems the current devs seem to use.

Mit freundlichen Grüßen,
