Я создал проект JPA (я использую OpenJPA 2.0 в качестве поставщика JPA).Access Datasource через проект JPA
IDE: IBM Rational Softwara архитектор Websphere программного обеспечения (RAD)
JPA поставщика: OpenJPA
Версия: 2,0
База данных: Oracle
Я создал источник данных в Websphere (версия 7.0) и попытался accss источник данных через JNDI. Найдите persistence.xml ниже.
<persistence version="2.0">
<persistence-unit name="DataSourceDemo">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>oracleDS</jta-data-source>
<class>com.nyl.ltc.auditlog.model.NylBatchPrint</class>
<properties>
<property name="openjpa.RuntimeUnenhancedClasses" value="supported" />
<property name="openjpa.ConnectionUserName"
value="admin" />
<property name="openjpa.ConnectionPassword" value="admin" />
<property name="openjpa.jdbc.Schema" value="SMSVC" />
</properties>
</persistence-unit>
</persistence>
Все транзакции с базой данных были успешными, но я получаю исключение ниже.
