log4j log file configuraiton

[Meryl Silverburgh <si...@gmail.com>]

Hi,

I am using log4j for my webapp logging (a servlet in a war file name
'test.war').

The current location of my log files are:
log4j.appender.DEBUG.File=${catalina.base}/debug.log

How can I change it so that it will be put under the directory of my
webapp (e.g. tomcat will create directory 'test' for my 'test.war').
Is there a variable that I can use?

i.e. something like:
log4j.appender.DEBUG.File=${catalina.base}/${web-app-directory}/debug.log

Thank you.

What I do is reference a property that I know my web application will 
set up for me upon application startup that is uniquely named, but 
predictable.  For instance, if your webapp context is named "MyApp", 
then you'd reference ${MyApp.log.home} and create this property 
*before* manually configuring log4j.

I set up code to generate the system property and value automatically 
in the log4j-sandbox.  I suggest grabbing the alpha2 or alpha3 tag if 
you want a codebase that will compile and deploy against Log4j 
1.2.x.  See my latest updates to the following wiki entry....
