Sure.
My Entity looks like the following:
@Entity
@Table(name="MPTZZY")
public class Group extends UpdateEntity{
/*Remark text*/
@Column(name = "TE_RMK",
length=20)
private String remarkText;
[...]
The according Junit Test is the following (EJB-Services are implemented
straight forward):
GroupServiceLocal tempGroupService = (GroupServiceLocal)
initialContext.lookup(GroupServiceLocal.class.getCanonicalName());
PersonServiceLocal tempPersonService = (PersonServiceLocal)
initialContext.lookup(PersonServiceLocal.class.getCanonicalName());
GroupPK tempPK=new GroupPK();
Person tempPerson=new Person();
tempPerson.getId().setPersonName("Marcel");
tempPerson.setAgeNumber((short) 29);
tempPerson.setRemarkText("TEST");
Group tempGroup=new Group();
tempGroup.getId().setGroupName("AA Team");
tempGroup.getId().setGroupNumber((short)1);
tempGroup.getId().setValidFromDate(new Date());
tempGroup.setRemarkText("AA Team");
tempGroup.getPersons().add(tempPerson);
tempPerson.setGroup(tempGroup);
tempGroupService.createGroup(tempGroup);
When running the test with the following property in the persistence.xml:
<property name="openjpa.MetaDataFactory" value="jpa"/>
everything works fine.
But when I change the property into:
<property name="openjpa.MetaDataFactory" value=
"org.apache.openjpa.persistence.PersistenceMetaDataFactory"/>
(which should be essentially the same, according to the document mentioned
in the mail before) the test fails with following error message:
<openjpa-1.2.1-r752877:753278 nonfatal general error>
org.apache.openjpa.persistence.PersistenceException:
DB2 SQL error: SQLCODE: -204, SQLSTATE: 42704, SQLERRMC:
I01W90.GROUPSQLCA OUTPUT[Errp=DSNXERT2, Errd=-335, 0, 0, -1, 0, 0]
DB2 SQL error: SQLCODE: -516, SQLSTATE: 26501, SQLERRMC: null
DB2 SQL error: SQLCODE: -518, SQLSTATE: 07003, SQLERRMC: null
FailedObject: prepstmnt 18898317 INSERT INTO i01w90.Group
(groupName, groupNumber, validFromDate, remarkText, date, time, user)
VALUES (?, ?, ?, ?, ?, ?, ?)
[org.apache.openjpa.jdbc.kernel.JDBCStoreManager$CancelPreparedStatement]
Obviously OpenJPA now does not use the column names I specified (for
example "TE_RMK") but instead uses the Java attribute name ("remarkText").

Subject: Re: Problems when using "openjpa.MetaDataFactory" Property
Can you post a unit test to help us better understand where you're running
into problems?
Thanks,
Rick
