Log4j Logging with JBOSS5

Question

Hello everyone,

I am using log4j as logging framework in my application and JBOSS 5 as Application server. I have created a log4j.properties file in the src folder of the application. That's how my log4j.properties looks like:

#Default log level to ERROR. Other levels are INFO and DEBUG.
log4j.rootLogger=INFO, ROOT
log4j.appender.ROOT=org.apache.log4j.RollingFileAppender
##Uncomment the next line and comment the 2nd next line when ready to deploy
log4j.appender.ROOT.File=/www/public/logs/myapp.log
##log4j.appender.ROOT.File=C:/myapp.log
log4j.appender.ROOT.MaxFileSize=100KB
#Keep 5 old files around.
log4j.appender.ROOT.MaxBackupIndex=5
log4j.appender.ROOT.layout=org.apache.log4j.PatternLayout
#Format almost same as WebSphere's common log format.
log4j.appender.ROOT.layout.ConversionPattern=[%d] %t %c %-5p - %m%n

#Optionally override log level of individual packages or classes
log4j.logger.com.webage.ejbs=INFO

But I can see that the myapp.log is never been created so I am not able to see any logs. Also I can server.log file in the sever logs folder but it has so much verbose that it's hard to track what's going on there. So I have two questions:
1. Why myapp.log is not being created.
2. Do u think the log4j.property file shown above is sufficient or not need to configure more stuff here.

Thanks,
Sameer

Most likely your log4j.properties is not getting picked up.

To configure log4j in Jboss 5 you would edit the file at

server/default/conf/jboss-log4j.xml

If you still want to use log4j.propeties, In the webapp, it should be placed in in your deploy/myapp.war/WEB-INF/classes

Follow the detailed instuctions at section "10.3.7. Using your own log4j.properties file - class loader scoping" in this link
