Following the receipt on log4j redirect stdout to DailyRollingFileAppender
And it was working until some point, and then it stopped working for some unknown reason.
Any idea of what can be wrong? i verified and im running exactly the same code as tieSystemOutAndErrToLog.
My log4j.properties is:
log4j.rootLogger = INFO, rollingFile, CONSOLE
log4j.logger.org.hibernate=INFO
log4j.logger.com.mchange=INFO
log4j.logger.com.opensymphony=WARN
log4j.logger.com.opensymphony.xwork2.ognl=ERROR
log4j.logger.org.hibernate.SQL=DEBUG, rollingFile
log4j.additivity.org.hibernate.SQL=false
#log4j.logger.com.mchange.v2.c3p0.impl.NewPooledConnection=DEBUG
#log4j.logger.com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool=DEBUG
#log4j.logger.com.mchange.v2.c3p0.impl.DefaultConnectionTester=DEBUG
log4j.logger.com.mchange.v2.resourcepool.BasicResourcePool=INFO
log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=/export/log/alpha/frontend.log
log4j.appender.rollingFile.MaxFileSize=10MB
log4j.appender.rollingFile.MaxBackupIndex=5
log4j.appender.rollingFile.layout = org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} - %p %t %c - %m%n
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} - %p %t %c - %m%n
in particular, im not able to log this event that is logged in catalina.out:
Dec 10, 2010 1:40:29 AM org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
UPDATED ANSWER: so i finally figured this out. for some obscure reason that i cannot even fathom, tomcat is not routing uncaught exceptions through log4j, and they are dumped to stdout, i had to log them in an exception page..
