Your Query is wrong.... Change this
return (CustomerCMP) em.createQuery("from Customer c where c.Name =:Name").getSingleResult() return em.createQuery("from Customer c").getResultList(); To return (CustomerCMP) em.createQuery("from CustomerCMP c where c.Name =:Name").getSingleResult() return em.createQuery("from CustomerCMP c").getResultList(); in both method calls.
