AFAIK you don't have to call rollover() in your code.
The appender works it out for you.
It will automatically roll the files when they reach a certain size.

If you want more, set MaxBackupIndex=10, and you will end up with 10 files:

If you set MaxBackupIndex=1 , then you will only get one backup file.
If you want more, set MaxBackupIndex=10, and you will end up with 10 files:
log.1
log.2
...
log.10

I have set the MaxBackupIndex of one , (two and tree ..) in the Config-file
log4j.appender.A1.MaxBackupIndex=1
I call the rollOver() in my applikation-code
cat = Category.getInstance("CAT");
PropertyConfigurator.configure( c:/itp/logmpl/log-test.properties"));
RollingFileAppender a =(RollingFileAppender)cat.getAppender("A1");
a.rollOver();
and run my test_applikation. There was only one time a bakeupfile with the name
C:/itp/logImpl/logtest.log.1
but not other more. Wenn i repeated the test, it wasn't anymore backeup file created
and the exist bakeupFile C:/itp/logImpl/logtest.log.1 was disposed.
i don'nt know why only one time was the bakeup file created.

>From the javaDoc on RollingFileAppender:
-----------------
rollOver
public void rollOver()
Implemetns the usual roll over behaviour.
If MaxBackupIndex is positive, then files {File.1, ..., File.MaxBackupIndex -1} are
renamed to
{File.2, ..., File.MaxBackupIndex}. Moreover, File is renamed File.1 and closed.
A new File is created to receive further log output.
If MaxBackupIndex is equal to zero, then the File is truncated with no backup files
created.
----------------------------
So your backup file would be
C:/itp/logImpl/logtest.log.1

Hi,
I have implemented a Simple class " LogImpl" that included one Catagory named "CAT".
I have to to specify a MaxFileSize and a Backupfile. The test-application with this
Class run correctly but I
don't know where is saved my Backup file and wath is the Name of the Backupfile .
Is it possible to specify the name of the Backupfile?
I can't find any Backup file .
the Configuration file look like.
# Set root category priority to DEBUG and its only appender to A1.
log4j.rootCategory=DEBUG, A1
# A1 is set to be a FileAppender which outputs to test.log.
#log4j.appender.A1=org.apache.log4j.FileAppender
log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.Append=true
log4j.appender.A1.File=C:/itp/logImpl/logtest.log
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c{1} %x - %m%n
log4j.appender.A1.MaxFileSize=10KB
# Keep one backup file
log4j.appender.A1.MaxBackupIndex=1
log4j.category.CAT=DEBUG
tanks,
Simin
