And another newbie question. I want to log my hibernate messages to a file or to the Mac OSX console.

I have my log4j.jar in my classpath as well as my hibernate.properties:

Code:
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file hibernate.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=hibernate.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ##

log4j.rootLogger=debug, stdout

log4j.logger.net.sf.hibernate=debug

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

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

### log prepared statement cache activity ###
log4j.logger.net.sf.hibernate.ps.PreparedStatementCache=debug


however, I cannot find my logfile 'hibernate.log' and my console doesn't spit the logs out either.

Turn on log4j debugging. Is it actually finding and using this file?

This should send logging to the console. You never add the appender named "file" to any of the loggers, so there would not be a file.

Probably a stupid question, but how to turn on logging with a servlet? Obviously a '-Dlog4j.debug=true' isn't appropiate here...

log4j.properties is in WEB-INF/classes btw, also tried to put it in WEB-INF/lib with no luck.

Is this on a servlet container that also uses log4j (like tomcat, etc) for its own logging?

Why? If you or your organization owns the box (meaning its not an ISP or ASP), thats a perfectly valid option. There is actually no other way to turn on log4j debugging such that the file being used for config is debugged out. You can set the debug attribute of the XML-based config, but by that time the config file has been read and the path to it is never logged.

Ok, frankly don't know how exactly, but will try to find out

1) place your log4j.jar file in WEB-INF/lib
2) place your config file in WEB-INF/classes

That's how the situation was in the first place :)

I don't use tomcat, so I am just passing along information from the log4j mailing list.

Ok, I've set debug=true and it's debugging to a log4j.log file now. However I cannot find any information regarding loading a log4j.properties file for my project, so it seems that it's not using log4j... But why?

I've put the properties-file in my WEB-INF/classes and the library in WEB-INF/lib, so that should be it right?

It all depends. Hibernate actually uses commons logging, which can delegate to either log4j or 1.4 logging.

As I mentioned in my first response to you, that config that you posted would never generate a hibernate.log file. You define the appender, but then never attach it to any loggers.

Have you checked in the tomcat logs? I think I remember reading that tomcat actually redirects the console to its log files.

I changed my config file since you mentioned it, but still no luck :(

I checked the tomcat logs and nothing I could find...

Ok, found a possibly related error in catalina.out:

Code:
com.opensymphony.user.util.ConfigLoader load
SEVERE: Exception
java.lang.NoClassDefFoundError: net/sf/hibernate/HibernateException
   at com.opensymphony.user.provider.hibernate.HibernateBaseProvider.init(HibernateBaseProvider.java:80)
   at com.opensymphony.user.util.ConfigLoader.addProvider(ConfigLoader.java:123)
   at com.opensymphony.user.util.ConfigLoader.access$100(ConfigLoader.java:37)
   at com.opensymphony.user.util.ConfigLoader$ConfigHandler.endElement(ConfigLoader.java:154)
   at
...


this is the error that the servlet throws up:

Code:
java.lang.RuntimeException: net/sf/hibernate/HibernateException
        com.opensymphony.user.util.ConfigLoader.load(ConfigLoader.java:74)
        com.opensymphony.user.UserManager.(UserManager.java:103)

        javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:853)


I've got hibernate.jar in my WEB-INF/lib directory...

This is the servlet code:
