I have this log4j configuration in my grails config.groovy
log4j = {
error \'org.codehaus.groovy.grails.web.servlet\', // controllers
\
just got answer from the grails' mailing list:
i just need to add
debug "grails.app"
bellow warn "org.mortbay.log"
case closed ! :)
please see Log4j: How to write to a specific appender?
After all the solution is to put the additivity setting to the package configuration:
info specialLog:'activityLog', additivity:false
I have exact the same jetty/tomcat env's. Spent hours to figure it out. The trick is to define the file location (a relative path in my case) as a global variable inside Config.groovy, customized it in the environment blocks, and use the variable location inside log4j closure.
