Java – how to find bean validation errors in NetBeans

I created an EJB Session Facade in NetBeans 7 to store my entities

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 try to save my EJB session bean in my database, I encounter the following error

Result: javax validation. Constraintviolationexception: the bean validation constraint: 'prepersist' was violated when the callback event performed automatic bean validation For more information, see embedded constraints

What I do is in my persistence Turn off my bean validation in the XML file I want to know what bean validation error happened, but I don't know how or where to find it or how to configure and capture it

My EJB facade is a simple class like t

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

Any tips?

Solution

To know what specific constraint violations have occurred, you can check the caught exceptions ConstraintViolationException. Getconstraintviolations () returns a set of constraintviolations that you can iterate and check
