Hi, I'm using log4j with hibernate. The log4j.properties is in my classpath, and contains:

log4j.rootLogger = DEBUG, R

log4j.appender.R = org.apache.log4j.RollingFileAppender
log4j.appender.R.File = C:/Archivos de programa/Apache Group/Tomcat 4.1/logs/gesticon.htm
log4j.appender.R.MaxFileSize = 300KB
log4j.appender.R.MaxBackupIndex = 2

#log4j.appender.R.layout = org.apache.log4j.SimpleLayout
log4j.appender.R.layout = org.apache.log4j.HTMLLayout


log4j.logger.net.sf.hibernate=info

### log just the SQL
#log4j.logger.net.sf.hibernate.SQL=debug

### log JDBC bind parameters ###
log4j.logger.net.sf.hibernate.type=info

### log schema export/update ###
log4j.logger.net.sf.hibernate.tool.hbm2ddl=debug

### log cache activity ###
#log4j.logger.net.sf.hibernate.cache=debug

### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.net.sf.hibernate.connection.DriverManagerConnectionProvider=trace


I'm using this to debug my application, and everything works fine. Logging info is written in my html file. But Hibernate writes logging info to console! Even if I turn off logging, hibernate still writes to the stdout.

What's happening?
Thanks

Ok, I've resolved the problem. The cause was the version of commons-logging.jar

I was using the one which comes in Tomcat 4.1.29 in common/lib foder, that seems to be older than the one included in Hibernate (doesn't contain Log4jCategoryLog.class). So I put the the jar included in hibernate in my WEB-INF/lib folder, and now everything works fine.
