log4j in grails : how to log into file?

Question

I have this log4j configuration in my grails config.groovy

log4j = {
    error  \'org.codehaus.groovy.grails.web.servlet\',  //  controllers
                   \         


        

Answer 1

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
