Hi Klaus-
I think your problem is in the way you're initializing your
DailyRollingFileAppender. The DailyRollingFileAppender (per the JavaDoc)
constructor takes a layout, filename, and date pattern. The filename you're
providing is "d:/is/share/system/log/error-log-". That is why log4j is
creating a file named "error-log-". The date pattern you provide
"yyyy-MM-dd-HH-mm" rolls over at the top of every minute. So, the
DailyRollingFileAppender is working correctly - just not the way you want
it. I don't know what the '.log' is for in your constructor.....?
Check out the JavaDoc for the DailyRollingFileAppender. It explains all the
various date patterns.
I am having a problem getting the DailyRollingFileAppender to roll over
daily. I am using a config file:
# D is set to be a DailyRollingFileAppender
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
# Set the name of the log file created: fms.log
log4j.appender.D.File=fms.log
# Set the date pattern to roll over daily (at midnight)
log4j.appender.D.DatePattern='.'yyyy-MM-dd
# Set the pattern
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%-15d{ABSOLUTE} %-10p (%c) - %m%n
The file is never rolled over - the log messages continue to be appended to
the original log. I heard that you had to have your server running when the
rollover is to occur - but that there was a DailyRollingFileAppenderExt jar
that solved this. Anybody know anything about this? I didn't have any
problems with the RollingFileAppender.....
Thanks-
Sara

Subject: DailyRollingFileAppender Question
Hi,
I'm new at log4j and have a problem.
I need to use the DailyRollingFileAppender to log messages. I create the
Appender using the following statement:
errorCategory.addAppender(new DailyRollingFileAppender(layout,
"d:/is/share/system/log/error-log-", "yyyy-MM-dd-HH-mm'.log'"));
The problem is a wrong file creation. Log4J creates a file called
"error-log-" and overwrites the file every minute with the next error
messages.
Does anyone know about troubles with this appender?
I use W2k and the following java version:
[y:\core] java -version
java version "1.2.2"
Classic VM (build JDK-1.2.2_007, native threads, symcjit)
Thanks
Klaus
