Code snippet:

@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@Table(name = "PCC_CAL_GNIC")
public class CommonGenericCalendar implements java.io.Serializable, Cloneable {
......
@OneToMany(mappedBy = "theGenericCalendar", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
protected Set<DateBase> theDateBases = new LinkedHashSet<DateBase>();
.....
}

@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@Table(name = "PCC_CAL_DATEBASE")
public class DateBase implements java.io.Serializable, Comparable<DateBase>{
...
}

@Entity
public class RepeatableDateBase extends DateBase implements
java.io.Serializable, Cloneable {

...
}

When I tried to save object of Datebase or RepeatableDateBase , discriminator column(DTYPE) is not getting updated.It is alway null. (It should be either Datebase or RepeatableDateBase)

The issue occurs only on project environment where <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WebSphereTransactionManagerLookup</property> is used.

The issue is not on local , I used <property name="hibernate.transaction.manager_lookup_class">org.apache.openejb.hibernate.TransactionManagerLookup</property>.

Can you please help on this ?

Thanks,
Gayatri
