notes on schuchert jpa tutor 2

the tutor is at http://schuchert.wikispaces.com/JPA+Tutorial+2+-+Working+with+Queries+1

lets follow..

• comment out the exception in the  unsuccessfulSingleResultTooManyEntries  test case of QueriesTest.. thus, it will pass..

 @Test// (expected = NonUniqueResultException.class)

    public void unsuccessfulSingleResultTooManyEntries() {

insertPerson();

        insertPerson();




        // This will fail because we expect a single result

        // but in fact there are 2 results returned.

        em.createQuery("from Person").getSingleResult();

    }

this is because,  getSingleResult() does not get angry when there are more than one records and just picks the first one..
