how to use env vars in log4j.properties file

2003-11-14 Thread Praveen Alavilli 
Hi,
I am trying to configure a DailyRollingFileAppender for my test app.
I want to set the log file to be in my server's (tomcat) log dir along 
with other log files. But if set the File path as

log4j.appender.MyappLog.File=${env.CATALINA_HOME}/logs/myapp.log

it throws this error:

log4j: setFile called: /logs/myapp.log, true
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: /logs/myapp.log (No such file or directory)

Is there any ther way to get this working apart from hard coding the 
file name/dir ?

thanks in advance
Praveen

I tried - they don't work either.

I asked the same type of question some time back and here is the 
solution that I got 
http://www.mail-archive.com/[EMAIL PROTECTED]/msg10021.html

I didn't try it because the new classes are not yet in the final release 
of log4J - they are only on sandbox.
