I am trying to migrate a project that was previously running with Hibernate 3.3.1 to Hibernate 4.1.10. I am running this in Java application mode using a simple test harness to get the basics of the migration worked out.

Here is my configuration file content:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<property name="cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>
<property name="generate_statistics">true</property>

<property name="connection.usetxapi">true</property>

<!-- Mapping Files -->
<mapping resource="maps/CustomTypes.hbm.xml" />
<mapping resource="maps/Activitylog.hbm.xml" />
...

</session-factory>
</hibernate-configuration>

The exception that I am getting is this:

This seems to be hooking the Hibernate Validation project functionality - but I didn't think that was required since it is not part of the required libs for the Hibernate project when you download the 4.1.10 zip. Here are the Hibernate related jar files that I have referenced by this project:

antlr-2.7.7.jar
ehcache-core-2.4.3.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.10.Final.jar
hibernate-ehcache-4.1.10.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar

Is there some configuration property that I need to change/add to eliminate this? Or is there a dependency now on Hibernate Core on Hibernate Validation regardless of any configuration settings?

I figured out the problem - turns out I had accidentally included both the WAS 8 server runtime and the Eclipse default IDE runtime in the path for the test project I was using - so apparently that was causing a problem with the classes being found as part of the Hibernate initialization. Once I eliminated the WAS 8 server runtime and just used the IDE runtime (since this was a simple standalone Java test application) Hibernate initialized correctly and a simple retrieval I had coded in this test application ran just fine.
