log4j in Tomcat and Glassfish

Hey guys Im new to log4j and was hoping I could get a quick bit of help...

Ive got the following file

Im trying to use the TOMCAT_HOME environment variable to locate the logs folder...Im not sure if this is the correct way to do things or not for a start. However Ive tried using just test.log and no log file is being created...Ive setup an stdout logger and that works so I know the file is being read but for some reason this lest.log doesnt get created....

Can anyone help me out as its driving me mad and I know it should be easy to correct but for some reason I just cant get it right

Forgot to mention that later Im going to include this in an ear file so any pointers on getting it to work with glassfish would also be great!

So a bit more detail as I think this is a likely cause of the problem but Im new to both OSX and log4j...would I need to alter the permissions on the logs foler inside of tomcat? I assumed that as the webapp is running within tomcat it wouldnt need to be altered but I could be mistaken

log4j doesn't pick up environment variables, does let you use system properties.

Syntax to use system property, if LOG_HOME were one:

system property on command-line looks like this (standalone java, NOT tomcat):

Tomcat may already have some system property you can use, I don't remember. Take a look at the log4j short manual, search for TOMCAT_OPTS to see how they suggested setting a different property.

Thanks that helped...there is a variable you can used which Ive added below in case anyone stumbles across this and needs the answer

Cheers for the guidance
It is sorta covered in the JavaRanch Style Guide.
