Does anyone know if it is possible to access the HOSTNAME environment variable in a log4j.properties file. Basically I'm using the email appender and would like to include the host in the email subject line so I can easily determine which server generated the email. I can hard-code this info but I was thinking there might be a way that tomcat can read something like
log4j.appender.email.subject=Java Application Error (${HOSTNAME})
