[jbpm-dev] [jBPM 3.2.6.SP1] Hibernate flush failed.

[Stefan Droog]

Hi all,

Currently I get the following error message. Does someone knows what goes wrong.

Configuration:
            <service name="persistence">
                  <factory>
                        <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
                              <field name="isTransactionEnabled"><false /></field>
                              <field name="isCurrentSessionEnabled"><false /></field>
                        </bean>
                  </factory>
            </service>
            <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />

Regards,
Stefan
