Hi,

I wrote a small Java program to configure an org.apache.log4j.Logger and log messages using it.

Excerpts from the Java file are:

package MyPackage;

//...

public class LogTest
{
   private static Hashtable cLoggerHash = new Hashtable();
   private void setLogInfo()
   {
       String sLogFile = "TestLogFile.log";
       Logger cLogger = Logger.getLogger( sLogFile );
       cLogger.setLevel( Level.toLevel("DEBUG") );
       PatternLayout cLayout = new PatternLayout();
       cLayout.setConversionPattern( "[%d{yyyy/MM/dd HH:mm:ss.SSS}]%C     - %m%n" );


       RollingFileAppender cFileAppender = new RollingFileAppender();
       //...
       cFileAppender.activateOptions(
);
       cFileAppender.setLayout( cLayout );
       cLogger.addAppender( cFileAppender );
       cLoggerHash.put( sLogFile, cLogger );
  }
  public static void main (String[] args)
  {
      LogTest logTest = new LogTest();
      logTest.setLogInfo();
      Logger cLogger = Logger.getLogger( "TestLogFile.log" );
      cLogger.log("TestLogFile.log", Level.INFO,  "\t ++++++++++++++ This is a test log +++++++++++++++++ ", null);

  }

The output is:
[2008/06/13 20:24:53.415]?     -     ++++++++++++++ This is a test log +++++++++++++++++


The fully qualified classname is NOT displayed.
Instead a "?" is displayed.

Please help.

Regards,
Debarshi

This question should have been asked on log4j-user, not log4cxx-user.  The most common cause is that the class file was not compiled with debug information.
