Hibernate: how do you adjust the default logging level (SJF4J and JDK 1.4 logger)?

java hibernate logging slf4j java.util.logging

I have a JavaSE/Hibernate test app (shell-based). I put the following JARs into the project's lib dir:

antlr-2.7.6.jar
commons-collections-3.1.jar
commons-lang-2.5.jar
dom4j-1.6.1.jar
hibernate-jpa-2.0-api-1.0.0.Final.jar
hibernate3.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
slf4j-api-1.6.1.jar
slf4j-jdk14-1.6.1.jar

As you can see, I'm using SLF4J with the JDK 1.4 logger. When I run my test app from the shell, Hibernate is very verbose because it is set to the INFO level by default:

09.12.2010 02:23:14 org.hibernate.annotations.common.Version <clinit>
INFO: Hibernate Commons Annotations 3.2.0.Final

How do I adjust the Hibernate logging level, to say WARNING?

EclipseLink for example let's you specify the level via a property (persistence.xml):

<property name="eclipselink.logging.level" value="INFO" />
<property name="eclipselink.logging.level.sql" value="FINE" />

Is there an equivalent in Hibernate?

I would always prefer to configure the logging framework with a central configuration file instead of several specific logging settings of libraries, because that's one of the reasons to use a logging framework at all.

Hibernate seems to follow that philosophy and since you are using JDK logging just configure the log level with a property file.
