Not sure why, but although JBoss AS (4.2.2GA) creates the boot.log file on startup, the file is always completely empty. Restarting JBoss, I can see that the timestamp of boot.log has been updated. I modified run.sh to capture $JAVA_OPTS as per http://wiki.jboss.org/wiki/JBossBootLogging but still, nothing appears in log/boot.log. Here is the log4j file I extracted from run.jar: ### ====================================================================== ### | ## ## | ## JBoss Bootstrap Log4j Configuration ## | ## ## | ### ====================================================================== ### | | ### $Id: log4j.properties 41281 2006-02-18 00:05:17Z starksm $ ### | | log4j.rootCategory=DEBUG, FILE, CONSOLE | | ### A bootstrap file appender | log4j.appender.FILE=org.jboss.logging.appender.FileAppender | log4j.appender.FILE.File=${jboss.server.log.dir}/boot.log | log4j.appender.FILE.layout=org.apache.log4j.PatternLayout | log4j.appender.FILE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n | log4j.appender.FILE.Append=false | | log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender | log4j.appender.CONSOLE.Threshold=INFO | log4j.appender.CONSOLE.Target=System.out | log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout | log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n | Is there something I'm missing?
