Hi,

I am using hibernate3.2.5.ga. I am getting following error when application is run.

What is the cause for this error?
Your answer is greatly appreciated.

dear friends,

It is working now.

Solution is to add following property to the hibernate configuration file hibernate.cfg.xml

<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>

Thanks a lot.

It also worked for me! (WebLogic+MySQL).

Thanks, it worked for me too.

While the suggested fix in this thread will work around the problem, the actual cause of the issue is a library conflict. We resolved this in our environment, WebLogic 10g (10.3.4), by adding an appropriate version of antlr.jar to the classpath prior to any other entries.

For instance (as written the WebLogic config.xml):


I can't speak for all scenarios, but this was our issue. I believe WebLogic was loading an earlier version of antlr that was not compatible with what Hibernate expected, but it was loaded higher in the classloader hierarchy so the library provided in the application did not take precedence.

The above suggestion of using the ClassicQueryTranslatorFactory simply sidesteps this particular library issue.

Hope this helps!
