DailyRollingFileAppender and path

[David]

Ok, I have DailyRollingFileAppender working, but I am surprised that
it is writing to root (or C:\ on windows). I have it configured this
way:

<appender name="SyslogInfoLogFile"
class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/info.log"/>
<param name="Append" value="true"/>
<param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %-5p
%c{2} - %m%n"/>
</layout>
</appender>

But my RollingFileAppender configured with the exact File parameter
writes to the correct directory of
jakarta-tomcat-3.3.1a\work\DEFAULT\ROOT.

I am working in a mixed environment (win/*nix) and dont' want to
hardcode the path. Can someone tell me why the
DailyRollingFileAppender doesn't write the same way as
RollingFileAppender, and how to force that?

Thanks for your help.
