Grails log4J Logging question on linux - linux

Question

I have been very frustrated about this.
I am trying to do the following:
Log all application related logs in application.log that are INFO or above
Understand what controls the configuration for catalina.out
Log only WARN to catalina.out
I am running my server on ubuntu and I have the default configuration for tomcat which includes a conf directory with a logging.properties. I renamed this file to l.p so it wouldn't conflict. (Not sure if this is a good idea)
In my config file, I have:
def catalinaBase = System.properties.getProperty('catalina.base')
if (!catalinaBase) catalinaBase = '.' // just in case
def logDirectory = "${catalinaBase}${File.separator}logs"
println "Log Directory: ${logDirectory}"
log4j = {
appenders {
rollingFile name: 'applog', file: "${logDirectory}${File.separator}application.log", layout: pattern(conversionPattern: '%d{dd-MM-yyyy HH:mm:ss,SSS} %5p %c{1} - %m%n'), maxFileSize: 1024
}
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'
info applog: 'grails.app'
root {
info 'applog'
}
}
As a result, I am getting three logs:
catalina.2011-01-17.log catalina.out localhost.2011-01-17.log
The catalina.out has the following output:
Log Directory: /var/lib/tomcat6/logs
log4j:WARN No appenders could be found for logger (org.apache.commons.beanutils.PropertyUtils).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
log4j:ERROR WARNING: Exception occured configuring log4j logging: Cannot invoke org.apache.log4j.FileAppender.setFile - argument type mismatch
I do NOT see the application.log in the log file directory. Any help would be appreciated I am really frustrated about this.
One more thing, in windows everything come out to the console and the application.log is created in the .grails\1.3.5\projects\<appnmae>\tomcat directory

Your problem is obviously that there's a type mismatch. Specifically, log4j is expecting a String when you're giving it a GString. Try replacing:
"${logDirectory}${File.separator}application.log"
With this:
"${logDirectory}${File.separator}application.log".toString()
EDIT: Please read this BUG
