Can't use @SqlResultSetMapping

[dinesh thalis]

I want to use @SqlResultSetMapping, so I wrote that code in My Customer entity class, below show that code

 @SqlResultSetMapping(
    name="CustomerMapping",
    entities={
        @EntityResult(entityClass=Customer.class),
        @EntityResult(
            entityClass=Customer.class,
            fields={
                @FieldResult(name = "oName", column = "OName"),
                @FieldResult(name = "cusType", column = "CusType")
            }
        )
    }
)   

After that I wrote query to retrieve data below show that method (this method in stateless session beans class)

  
    public List findCustomer() {
        List a = null;
        try {
            Query query = em.createNativeQuery("SELECT cus.oName ,cus.cusType FROM Customer cus", "CustomerMapping");
            a = query.getResultList();
        } catch (Exception e) {
            System.out.println(e);
        }
        return a;
    }
  

After calling this method below exception thrown
