    Description

      1. My env is : WPS6.1, DB2 9.0, OpenJPA 1.2.0

      2. The followed is my persistence.xml configuration file:
      <persistence-unit name="derby.ojpa">
      <provider>
      org.apache.openjpa.persistence.PersistenceProviderImpl
      </provider>
      <jta-data-source>jdbc/jpa</jta-data-source>
      <mapping-file>orm.xml</mapping-file>
      <properties>
      <property name="openjpa.TransactionMode" value="managed"
      />
      <property name="openjpa.ConnectionFactoryMode" value=
      "managed"/>
      <property name="openjpa.jdbc.DBDictionary" value="db2"/>
      <property name="openjpa.jdbc.EagerFetchMode" value="join"
      ></property>
      <property name="openjpa.InverseManager" value="true"/>
      <property name="openjpa.RetainState" value="true"/>
      <property name="openjpa.AutoDetach" value="nontx-read"/>
      <property name="openjpa.NontransactionalRead" value=
      "false"/>
      <property name="openjpa.NontransactionalWrite" value=
      "false"/>
      <property name="openjpa.ConnectionRetainMode" value=
      "transaction"/>
      </properties>
      </persistence-unit>

      3. I enable global transaction of SCA component , make sure tx is started,
      and invokes several DAO operations in one of the SCA component operation
      named "updateCaseStatus".
      such as CaseMgmtImpl SCA component sequentially invokes DAO operations

      CaseStatus cStatus = statusDAO.findByCaseStatusPK(caseeStatus);
      Casee casee = caseDAO.findByCaseePKWithRef(caseeId);
      casee.setBusinessStatus(cStatus);
      caseDAO.updateCasee(casee);

      In caseDAO.findByCaseePKWithRef :
      em = emf.createEntityManager();
      em.joinTransaction();
      result = (Casee)em.find(Casee.class, caseID);
      em.close();
      In statusDAO.findByCaseStatusPK :
      em = emf.createEntityManager();
      em.joinTransaction();
      result = (CaseStatus)em.find(CaseStatus.class, statusCode);
      em.close();

      In caseDAO.updateCasee :
      em = emf.createEntityManager();
      em.joinTransaction();
      Casee mergedcasee = em.merge(casee);
      em.flush();
      em.close();

      4. Then at the end of the sca component updateCaseStatus method, such
      errors throwed.

      5. According to my analysis,

      CaseStatus cStatus = statusDAO.findByCaseStatusPK(caseeStatus); —
      cStatus with StateManagerImpl & PNonTransState
      Casee casee = caseDAO.findByCaseePKWithRef(caseeId); —
      casee with StateManagerImpl & PNonTransState
      casee.setBusinessStatus(cStatus); —
      casee with StateManagerImpl & PDirtyState
      caseDAO.updateCasee(casee); —
      in updateCasee method, casee(PDirtyTransState -> PNewState)

      em = emf.createEntityManager();
      em.joinTransaction();
      Casee mergedcasee = em.merge(casee); —
      casee with StateManagerImpl & PDirtyState
      —
      mergedcasee with StateManagerImpl & PNewState
      em.flush(); —
      Here, a record would be inserted into DB
      em.close();
