send log output to different files in grails 1.3.2

Question

I want to have log output of my packages or classes in a specific appender. But everything is printed out to the root-logger.

Here is my config:

log4j = {
    appenders {
        console name:'stdout', layout:pattern(conversionPattern: '%c{2} %m%n')
        file name:'grailslog', file:'grails.log', threshold:org.apache.log4j.Level.DEBUG
        file name:'mylog', file:'mylog.log', threshold:org.apache.log4j.Level.DEBUG
    }

    error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
           'org.codehaus.groovy.grails.web.pages', //  GSP
           'org.codehaus.groovy.grails.web.sitemesh', //  layouts
           'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping
           'org.codehaus.groovy.grails.web.mapping', // URL mapping
           'org.codehaus.groovy.grails.commons', // core / classloading
           'org.codehaus.groovy.grails.plugins', // plugins
           'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
           'org.springframework',
           'org.hibernate',
           'net.sf.ehcache.hibernate'

    warn   'org.mortbay.log'

    debug  'grails.app'

    debug  mylog: 'my.package', additivity: true

    root {
      error 'grailslog'
      additivity = true
    }
}

I also tried this syntax:

log4j = {
    appender.stdout = "org.apache.log4j.ConsoleAppender"
    appender.'stdout.layout'="org.apache.log4j.PatternLayout"
    appender.'stdout.layout.ConversionPattern'='[%r] %c{2} %m%n'

    appender.mylog= "org.apache.log4j.DailyRollingFileAppender"
    appender.'mylog.File' = "mylog.log"
    appender.'mylog.layout' = "org.apache.log4j.PatternLayout"
    appender.'mylog.layout.ConversionPattern' = '%d{[ dd.MM.yy HH:mm:ss.SSS]} [%t] %-5p %c %x - %m%n'

    appender.grailslog = "org.apache.log4j.DailyRollingFileAppender"
    appender.'grailslog.File' = "grails.log"
    appender.'grailslog.layout' = "org.apache.log4j.PatternLayout"
    appender.'grailslog.layout.ConversionPattern' = '%d{[ dd.MM.yy HH:mm:ss.SSS]} [%t] %-5p %c %x - %m%n'

    rootLogger="error,stdout,grailslog"

    logger {
      grails="info,stdout,grailslog"
      my.package="debug,mylog"
    }
}

But this doesn't work any more with the current grails version.

A short update:

Grails has a new Documentation for the log-DSL (domain specific language). Therefore the code above has a wrong syntax.

They wrote:

... the name of the logger is 'grails.app.(type).(className)' ...

Answer 1

I managed to use my other log file.

Instead of using a logger with the package name I used a custom name and initialized my logger with this.

debug  mylog: 'myLog', additivity: true

[...]

def log = Logger.getLogger("myLog")
