У меня есть следующий объект:
@Entity
@Table
@NamedQuery(name = Constants.FINDALLFINDERNAME,
query = Constants.FINDALLQUERY)
public class Customer extends AuditableEntity {
...
@ElementCollection(fetch = FetchType.EAGER)
@CollectionTable(name = Constants.PHONES, joinColumns = @JoinColumn(name = Constants.CUSTOMER_ID))
@Column(name = Constants.CUSTOMER_PHONES, nullable = true)
private List<Phone> phones;
Я хочу импортировать следующие данные в мою схему во время теста:
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<CUSTOMER id='101' USERNAME="user1" FIRSTNAME="Mick" LASTNAME="Knutson"/>
<PHONES AREACODE="415" P_NUMBER="5551212" TYPE="WORK" CUST_ID="101" />
</dataset>
Но я получаю эту ошибку:
[EL Info]: 2011-01-31 10:57:56.945--ClientSession(30624226)--Communication failure detected when attempting to create transaction on database. Attempting to retry begin transaction.

Вот мой модульный тест:

Может кто-нибудь помочь мне понять, как импортировать CollectionTables с DBUnit?
