Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event: 'prePersist'

Question

I created an EJB Session facade in my Netbeans 7 for saving my entity. I have a manytoone mapping between my Insurance and RatePlan Class.

public class Insurance{
    @ManyToOne(optional=false) 
    @JoinColumn(name="PLAN_ID")
    private RatePlan plan;
}
public class RatePlan{
    @OneToMany(mappedBy="plan")
    private Set<Insurance> insuranceItems;
}

When I tried saving in my database using my EJB Session Bean, I am encountering below error.

Caused by: javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'. Please refer to embedded ConstraintViolations for details.

What I did was to turn off my Bean validation in my Persistence.xml file. I would like to know what Bean validation error has occurred but I dont know how or where to find it or how to configure and catch it.

My EJB facade is a simple class like tis.

public class InsuranceFacade{
    public void saveInsurance(Insurance insurance){
        em.persist(insurance);
    }
}

Any hints?

To know what specific constraint violations have occurred, you could just inspect the exception caught. ConstraintViolationException.getConstraintViolations() returns a Set of ConstraintViolations which you can iterate and inspect.
