Dear Gunter,

Any idea where I can get the DatedFileAppender  ?
I have tried to go to the cvs but couldn't find it. 

The only thing close to it is DailyFileAppender1 from Eirik Lygre. 
Sounds like your DatedFileAppender doesn't need additional parameter
and meet my requirement.


Thanks for your help

Try  the DatedFileAppender. I'm not sure if it is already contained in the
standard  version or if you still have to download the class as an extension. At
 the end a sample of my xml config file with a DatedFileAppender and a  ConsoleAppender.
The occ.log for the filename will be changed to  'occ-20010919.log' for Sep-19-2001.
   
  
Try  following code for the error logging:
   
  
      // make sure everything  sent to System.err is logged
      System.setErr(new  PrintStream(new LoggingOutputStream(Category.getRoot(),
Priority.WARN),  true));
  
  
Hope  this helps!? Gunter

    Subject:    Beginner Questions
    
    
    
Dear All,
    
I am a    new user of Log4J. I got 2 question, which might have been questions
before,    but I am not sure what the best pattern for my issue to start
searching    it.
    
Here are the questions : 
    
      There is a requirement to use a log file with date as the filename
(i.e      20010304app.log) based on current date. Could I do this with log4j?
If yes,      how ? With this, I don't have to bother about      log4j.appender.R.MaxBackupIndex
 in my config anymore.      
      Could I stream the Exception.printStackTrace() into the
log4J      logging system? How  ?
      
    
TIA
    
Lukman
