Help with replacing tokens for log file name

[Wendy Smoak <We...@asu.edu>]

I'm not sure whether this is more Ant or Log4j, so please send me along
if I'm not in the right place.

In build.xml, I have this:
   <target name="props-dev" depends="copy-props">
     <replace file="${propsdir}/log4j.properties" 
                token="@logFileName@" 
                value="${env.TOMCAT_HOME}\logs\${context}.log"/>
   </target>

It's turning this in log4j.properties:
   log4j.appender.daily.File=@logFileName@
into this:
 
log4j.appender.daily.File=c:\jakarta\jakarta-tomcat-4.1.29\logs\coldev.l
og

Unfortunately, this results in log messages going to a file called
   jakartajakarta-tomcat-4.1.29logscoldev.log
in the c:\jakarta\jakarta-tomcat-4.1.29\bin directory.

I tried quoting  @logFileName@ but that produced:
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException:
"c:jakartajakarta-tomcat-4.1.29logscoldev.log" (T
he filename, directory name, or volume label syntax is incorrect)
when the webapp is started.

I think the answer is to escape the backslashes, but since part of it
comes from a system property, I don't see how.

Is there a way to do this on Windows?  I can just use a .properties file
for the token/value replacements, I was trying to avoid hard-coding as
much as possible though.
