Question: How do you define logging for your application?

Answer: To define logging for your application, you have to download the log4j framework (log4j.jar) from the apache site.
Once log4j jars are downloaded, make sure that these jars are in classpath of your application. lets say you have web-application need to be added log4j. In this case, log4j jars are copied to WEB-INF/lib folder of your web application.
create new file either logging.properties or log4j.xml which will be copied to WEB-INF/classes folder.
logging.properties/log4j.xml contains the all the configuration related to logging mechanism and logger level and package that you want to define logger level.

Example:

logging.properties:

logger.level=INFO

logger.handlers=CONSOLE,FILE,RejRec

handler.RejRec=org.jboss.logmanager.handlers.PeriodicRotatingFileHandler

handler.RejRec.level=WARN

handler.RejRec.formatter=RejRec

handler.RejRec.properties=append,autoFlush,enabled,suffix,fileName

handler.RejRec.append=true

handler.RejRec.autoFlush=true

handler.RejRec.enabled=true

handler.RejRec.suffix=.yyyy-MM-dd

handler.RejRec.fileName=E:\Docs\WithoutBook\DID\jboss-eap-6.2\standalone\log\RejectedRecords.log

log4j.xml:

<log4j:configuration>

<appender-ref ref="LOG"/>

</appender>

</layout>

</appender>

<appender-ref ref="MEETING-APP-LOG"/>

</logger>

<root>

<appender-ref ref="ASYNC"/>

<appender-ref ref="ERROR-LOG"/>

</root>

</log4j:configuration>
