log4j in grails : how to log into file ?

Question

hi,

I have this log4j configuration in my grails config.groovy

log4j = {
    error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
                   'org.codehaus.groovy.grails.web.pages' //  GSP
    warn 'org.mortbay.log' 


    appenders {
        rollingFile  name:'infoLog', file:'info.log', threshold: org.apache.log4j.Level.INFO, maxFileSize:1024
        rollingFile  name:'warnLog', file:'warn.log', threshold: org.apache.log4j.Level.WARN, maxFileSize:1024
        rollingFile  name:'errorLog', file:'error.log', threshold: org.apache.log4j.Level.ERROR, maxFileSize:1024
        rollingFile  name:'custom', file:'custom.log', maxFileSize:1024
    }

    root {
        info 'infoLog','warnLog','errorLog','custom', stdout
        error()
        additivity = true
    }
}

the infoLog,warnLog and errorLog was from the previous question ... they were working well.

now I add new RollingFile wit name "custom" ...

I tried to log from my controller and service using log.info("something .... ${obj}"); but it seems that message was not inserted into custom.log, do I need to add something to the configuration ?

thank you !!

I have a log4j properties in Config.groovy. log4j = {

        grails.serverURL = "http://localhost:8080/${appName}"
        def catalinaBase = System.properties.getProperty('catalina.base')
        if (!catalinaBase) catalinaBase = '.'   // just in case
        def logDirectory = "${catalinaBase}/logs"

        appenders {
            appender new org.apache.log4j.DailyRollingFileAppender(name: "friendsJob", datePattern: "'.'yyyy-MM-dd", file: "${logDirectory}/Sg/friends/friendsJob.txt", layout: pattern(conversionPattern: '[%d{yyyy-MM-dd hh:mm:ss.SSS}] %p %c{5} %m%n'))

        info appLog: 'grails.app.tagLib'
        info appLog: 'grails.app.domain'

}

its work when i run the application from Intellij using Jetty. But when i create the war file and deploy to tomcat log files are created but no log generted.

Can some one help me. Where the log4j.properties file created in war. I also add my separate log4j.property file in /WEB-INF/lib/grails-core also. but of no use.

Answer 4

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.
