How can I get Tomcat's logging.properties to recognize my Catalina variables? -

we have several tomcat 7 instances installed on different servers. deploy same app different tomcats (for different customers) differences being configs. in effort standardize logging locations, etc., trying make apps "universal" deploying war file tomcat instance wire automatically don't have remember change app customer 1 , again customer 2, etc.

anyway, in each tomcat/conf folder, have added properties end of catalina.properties file. example:

# custom logging log.base=c:/logs/tomcat/myapp log.file=myapp.log 

now, in application's log4j.cfg file, have:

log4j.appender.r.file=${log.base}/${log.file} 

and in application's myapp.cfg have:

logfile=${log.file} 

works great when deploy. tomcat puts should except what's in logging.properties file.

that file contains:

1catalina.org.apache.juli.filehandler.directory = ${catalina.base}/logs 2localhost.org.apache.juli.filehandler.directory = ${catalina.base}/logs 3manager.org.apache.juli.filehandler.directory = ${catalina.base}/logs 4host-manager.org.apache.juli.filehandler.directory = ${catalina.base}/logs 

but want change ${catalina.base}/logs use own ${log.base} variable. tomcat (or perhaps log4j?) doesn't recognize this. instead, creates directory named "${log.base}" in tomcat root folder.

i read can declare custom variables in setenv.bat file. did , still didn't work.

how can fix this?

btw, using windows, tomcat 7 , windows service install (with gui).

thanks

set environment variable java_opts in setenv.bat. in way give java vm argument. following works in setenv.sh in linux:

export java_opts="-dlog.base=/logs/tomcat/"

now should able use ${log.base} in logging.properties
