using log4j with hibernate and glassfish 3.0.1

I'm trying to setup hibernate 3.5.3 with JPA on glassfish 3.0.1;

I'm using a netbeans 6.9.1 enterprise project; I added all the required hibernate files and everything is fine except logging...

I added to the project classpath like the docs say the following (only the log related jars listed):

-slf4j-api-1.5.8.jar

-slf4j-log4j12-1.5.8.jar

-log4j-1.2.16.jar

-log4j.properties which looks like:

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

log4j.rootLogger=info, stdout

log4j.logger.org.hibernate.test=info
log4j.logger.org.hibernate.tool.hbm2ddl=debug

I also activated debug using -Dlog4j.debug JVM property.

As soon as I deploy I get this in the server log:

SEVERE: log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
SEVERE: log4j:ERROR The class "org.apache.log4j.Appender" was loaded by

SEVERE: log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Any ideas on how do I fix this? Thank you!

EDIT

I tried to remove log4j from my project as Tushar Tarkas suggested:

SEVERE: org/apache/log4j/Level
java.lang.NoClassDefFoundError: org/apache/log4j/Level
        at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:223)
        at org.slf4j.LoggerFactory.bind(LoggerFactory.java:120)
        at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:111)
        at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:269)

EDIT2: SOLUTION

I don't know why, but if I copy log4j-1.2.16.jar file in /domains/domain1/lib it's working.

EDIT3:

Pascal, here's what GF deploys.

Try to use application-specific classloading with Glassfish.

Place the log4j.jar into [Glassfish-Install-Dir].[PATH-TO-DOMAIN]/lib/applibs. You can also make a new directory to keep things clean: [Glassfish-Install-Dir].[PATH-TO-DOMAIN]/lib/applibs/MY_APPLICATIONS_DEPENDENCIES

After you have done that you have to specify to load log4j when you deploy your application. There are two options: 1. Admin console / web interface: fill in the information for log4j in the option liberaries 2. Use the asadmin deploy command with the ----libraries option and specify comma-separated paths. For details, see the Oracle GlassFish Server 3.1-3.1.1 Reference Manual. (cited from Oracle GlassFish Server 3.1 Application Development Guide)

I could find some discussions related to similar problem. The problem is with glassfish version 3 and above. The classes seem to be loaded by different class loaders.

Check this.
