i am using log4j
and my configuration is as follows:

log4j.rootLogger=OFF, stdout, rootLog
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.rootLog=org.apache.log4j.RollingFileAppender
log4j.appender.rootLog.File=${user.home}/logs/mylog.log
log4j.appender.rootLog.MaxFileSize=10000KB
log4j.appender.rootLog.MaxBackupIndex=3
log4j.appender.rootLog.layout=org.apache.log4j.PatternLayout
log4j.appender.rootLog.layout.ConversionPattern=%p %t %c - %m%n

# Control/Limit integrated frameworks logging messages

log4j.logger.org.hibernate=OFF
log4j.logger.org.springframework=OFF

although i am turning off the root logger and the hibernate logging

i am still seeing info in the console from:

2099 [main] INFO org.hibernate.cfg.SettingsFactory
2440 [main] INFO org.hibernate.tool.hbm2ddl.SchemaExport
3239 [main] WARN org.hibernate.util.JDBCExceptionReporter

how to stop that, please advise, thanks.

    That’s not really what your log4j config is. The output you’ve listed doesn’t match either of the conversion patterns you showed in the config file. It’s using some other configuration.

    Update: Based on your updated question, if you’re using an SLF4J Logger, then you aren’t even using Log4J because you’re using the slf4j-simple binding, which “outputs all events to System.err. Only messages of level INFO and higher are printed” per the SLF4J manual. To use Log4J, you have to use the slf4j-log4j12 binding.
