Subject log4j.properties and substition of user properties
Date Wed, 19 Aug 2009 21:22:05 GMT

I have the following in a log4j.properties

log4j.appender.LogFile.layout.ConversionPattern=[%6r] %8c{1} : %m%n

This is being used by an invocation of ANT in which the command line

    ....  -Dwork.dir=/a/valid/directory .....

The ANT property ${work.dir} is successfully referenced in the ANT
buildfiles, but log4j resolves it to the null string, attempting to put the
build.log file in the root, which obviously doesn't work.  I know ANT is
using the log4j.properties because when I put in an absolute path for
LogFile.file it works correctly.

Based on my reading of the docs, I expected this to work, and the fact that
${work.dir} gets replaced with a null string tells me that log4j is
attempting to resolve it, but just doesn't have a value for it.  What do I
need to do to get the value to log4j?

If this question is more appropriate for an ANT forum I apologize in
