hibernate tomcat mysql

Hi there,

I got a problem trying to make tomcat 5, flex and hibernate work together.
I got the following error in tomcat log :

tomcat log

SEVERE: StandardWrapper.Throwable
flex.messaging.config.ConfigurationException: Unable to create service 'flex.data.DataService' for 'data-service' due to the
following error: Error instantiating application scoped instance of type 'flex.data.assemblers.HibernateAssembler' for

flex.data.adapters.AdapterException: No Hibernate mapping was found for entity name
'myProject.vo.User ' configured in destination 'null'.

In the catalina log I got the following info on Hibernate log
