For the System property issue I tried this :
<appender name="specialAppender"
class="org.apache.log4j.DailyRollingFileAppender">
<param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
<param name="File"
value="C:/UserTemp/matthew016/${log.name}"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p
[%-30.30c{2}] %m%n"/>
</layout>
</appender>
And in my Java applciation I execute this line before I need to log in
the special appender :
System.setProperty("log.name",idRequest+".log");
[2/28/07 12:16:32:297 CET] 3e89f5a2 SystemErr R log4j:ERROR
setFile(null,true) call failed.
[2/28/07 12:16:32:297 CET] 3e89f5a2 SystemErr R
java.io.FileNotFoundException: C:\UserTemp\matthew016 (Access is denied)
Though something like this <param name="File"
value="C:/UserTemp/matthew016/myLog.log"/> works.
I tried also a simple thing :
If I do this :
<param name="File" value="C:/UserTemp/matthew016/updates/myLog.log"/>
[2/28/07 12:15:17:669 CET] 3e8d3584 SystemErr R log4j:ERROR
setFile(null,true) call failed.
[2/28/07 12:15:17:669 CET] 3e8d3584 SystemErr R
java.io.FileNotFoundException: C:\UserTemp\matthew016\updates\test.log
(The system cannot find the path specified)
It gives me the same error, because it cannot find the directory
"updates" under dir "matthew016".
Though I create this dir dynamically in my application *before* any logs
need to be stored trhough the appender specified output.

***** This message comes from the Internet Network *****
Yes exactly :-) Thank u very much,
I realized I did this all wrong.
I have read the Log4J tutorial,
I did the points 1 & 2, but for I have some difficulties on how to
implement point 3 & 4
I switched this to XML :
<appender name="mainAppender"
class="org.apache.log4j.FileAppender">
<param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
<param name="File" value="C:/UserTemp/matthew016/app.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p
[%-30.30c{2}] %m%n"/>
</layout>
</appender>
<appender name="specialAppender"
class="org.apache.log4j.FileAppender">
<param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
<param name="File" value="C:/UserTemp/matthew016/ >>>>SYSTEM
PROPERTY<<<< "/>
<param name="File" value="C:/UserTemp/matthew016/app.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p
[%-30.30c{2}] %m%n"/>
</layout>
</appender>
<appender name="consoleAppender"
class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c{1} - %m%n"
/>
</layout>
</appender>
<root>
<priority value ="info" />
<appender-ref ref="mainAppender" />
<appender-ref ref="specialAppender" />
<appender-ref ref="consoleAppender" />
</root>
* In my Java class I don't know how I can specify which appender I
should use,
Or maybe I can specify the logger in the log4j.xml file ?
* I don't knwo how to use the system property,
In the program I suppose I just need to do something like this :
System.setProperty("myProp","updates/"+dirNumber);
But what do I need to specify in the XML file ?
* Is it correct what I did in the special appender ? I specified the
file which must include the system property and the same file as the
main appender,
is this the good way.
Thank u for any hints!

This should do what you want:
1. Switch to XML config.
2. Define your main appender and special appender
3. Use a system property for the name of the file in the special
appender.
4. Make sure you have your loggers setup so logs from the special part
of your code go to the special appender.
