I have this logging configuration in my Config.groovy file. This is a development environment, started as such. I have verified the file exists and there are 775 perms on the file, but nothing is getting output to the file.

// set per-environment serverURL stem for creating absolute links
environments {
   production {
      grails.serverURL = "http://www.changeme.com"
   }
   development {
      grails.serverURL = "http://localhost:8080/${appName}"
      logFilePath = "/Users/davea/Tomcat/logs/log4j.log"
   }
   test {
      grails.serverURL = "http://localhost:8080/${appName}"
   }
}

// log4j configuration
log4j = {
   console name:'Appender1',
           layout:pattern(conversionPattern: '%-4r [%t] %-5p %c %x - %m%n')
   rollingFile name:'Appender2', maxFileSize:1024 * 1024, file:logFilePath,
               layout:pattern(conversionPattern: '%-4r [%t] %-5p %c %x - %m%n')
   root {
      debug 'Appender1', 'Appender2'
   }
}

Can anyone tell what's wrong with my configuration? Thanks, - Dave
