Ich versuche Hibernate JPA mit einem Derby JDBC Treiber mit "autocommit" zu betreiben. Nach dem Aufruf von persist() für ein neues Objekt wird das Objekt allerdings nicht committed (obwohl der Treiber autocommit eingeschaltet hat - siehe LOG file unten!)
Die Persistence Unit ist wie folgt konfiguriert:
Code:
<persistence-unit name="unit">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<mapping-file>META-INF/orm.xml</mapping-file>
<class>contact.Contact</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect" />
<property name="hibernate.connection.url" value="jdbc:derby://localhost:1527/JavaDB;create=true" />
<property name="hibernate.connection.username" value="user1" />
<property name="hibernate.connection.password" value="user1" />
<property name="hibernate.connection.autocommit" value="true" />
<property name="hibernate.hbm2ddl.auto" value="create" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.transaction.factory_class"
value="org.hibernate.transaction.JDBCTransactionFactory" />
</properties>
</persistence-unit>
Die gleiche Anwendung ohne JPA (also nur Hibernate API) berücksichtigt autocommit es funktioniert also wie erwartet. Die JPA Lösung funktioniert nur wenn der persist() Aufruf mit begin und commit transaction umklammert wird!
Hier meine Frage: benötigt JPA weitere Konfigurationsparameter damit autocommit funktioniert?
Ich verwende hibernate 3.2.1.ga und derby 10.2.2.0.
Zur Unterstützung füge ich noch den Log der JPA Lösung an:
