-----------------------------------------
I found a dirty workaround:
Replace this:
@ManyToOne(optional=false)
@JoinColumn(name="MASTER", nullable=true,
referencedColumnName="MASTER_ID")
private MasterUk1 master;
With this:
@ManyToOne(optional=false, targetEntity=MasterUkBase.class)
@JoinColumn(name="MASTER", nullable=true,
referencedColumnName="MASTER_ID")
private MasterUk1 master;
This will work only for One-Level in the Subclassing hirarchy, what if we have mor then
one level ?

---------------------------------------
bq. This will work only for one level in the subclassing hierarchy, what if we have more
then one level ?
I am having this same problem. We have the following type of structure:
{noformat}
@MappedSuperclass
public abstract class AbstractBean {
protected Long versionNumber;
....
@MappedSuperclass
public abstract class AbstractFoo extends AbstractBean {
protected Long fooId;
@Entity
@Table(...)
public class Foo extends AbstractFoo {
.....
{noformat}
And are trying to pull in a Foo like this:
{noformat}
@ManyToOne
@JoinColumns({ @JoinColumn(name = "versionNumber", referencedColumnName =
"versionNumber"),
@JoinColumn(name = "fooId", referencedColumnName = "fooId") })
protected Foo foo;
{noformat}
Unfortunately the only way of solving it I have found so far is to pull all the necessary
fields into one of the classes, e.g.:
{noformat}
@MappedSuperclass
public abstract class AbstractFoo extends AbstractBean {
protected Long fooId;
@Column(name = "versionNumber"}
protected Long justHereForMappingMagic; // Named something different so the compiler
doesn't complain
{noformat}
And then mapping explicitly to that class:
{noformat}
@ManyToOne(targetEntity = AbstractFoo.class)
@JoinColumns({ @JoinColumn(name = "versionNumber", referencedColumnName =
"versionNumber"),
@JoinColumn(name = "fooId", referencedColumnName = "fooId") })
protected Foo foo;
{noformat}
