Hi Tim-
I use the DailyRollingFileAppender to roll over my log file daily at
midnight. I couldn't get the regular DailyRollingFileAppender class to work
properly so I use the DailyRollingFileAppenderExt class and that works
great. The XML properties are similiar. However, I don't believe you can
set the maximum number of logs with the regular DailyRollingFileAppender
class. To do this, you would also need to use DailyRollingFileAppenderExt.
Here's my portion of XML config (using DailyRollingFileAppenderExt):
<appender name="dailyRollFile"
class="org.apache.log4j.DailyRollingFileAppenderExt">
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<param name="MaxLogs" value="30"/>
<param name="File" value="logs/fms.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-15d{ABSOLUTE} %-10p
(%c) - %m%n"/>
</layout>
</appender>
1. You set the MaxLogs property. This can be any integer value. This is
only available using the DailyRollingFileAppenderExt class.
2. For the different date patterns, look at the DailyRollingFileAppender
javadoc. It explains 6 different date patterns.
3. Can't help you here - I run JBuilder5 with Tomcat for dev and JRun for
prod.
Hope this helps!

Subject: I can not use DailyRollingFileAppender properly
Hi All,
I wonder whether anybody can give me a completely example of the XML
configuration file for the DailyRollingFileAppender? If you don't mind, I
have the following questions:
1. How can I let the DailyRollingFileAppender to keep only one generation of
the rolled over file? i.e, if I want to roll over once a week, I only want
to keep the log file for this week and last week, no more than that.
2. The following is my XML configuration file(roll over once a week is not
set, I don't know how). What else I missing?
3. If I do not have the weblogic/logs directories, will log4j create them
for me? Or do I have to phisically create those two directories under /work
before hand? If the answer is yes, how can I do it?
Thanks.
Tim
