I have looked but was not able to find a direct answer. I found others with very similar classes but not the same problem.

The problem is given the class heirarchy below, Hibernate can not find my setter method for my table key (setKey(Long key)).

Now, if I remove 'final' from the methods and include the method in each class it appears to work:

private void setKey(Long key) {
super.setKey(key);
}

however, without that, the subclasses can not see the setters.

Is anyone aware of a problem here? I have included class snippets and some mapping files. Thanks.

[Persistable] (abstract, has no table, not mapped -> has attributes and
| methods needed by subclasses)
|
+---Person (abstract, extends Persistable, has a table)
|
|
+---Parent (abstract, extends Person, has a table)
|
|
+---Father (concrete, extends Parent, has a table)

/****
The goal is to have every persistable class extend this class. It has the
key, version and all necessary methods. I made the methods final so
that subclasses can not override. There is not table for this class. I start
the Hibernate mapping with subclasses that extend this class.

I am using subclass per table mapping
*****/
public abstract class Persistable implements Serializable, Loggable {

// ..... some public static final stuff removed .... //

private Long key = null; // MSSQL Server identity column
private Timestamp version = null;
private String recordStatus = NEW;
private User lockedBy = null;
private Date dateLocked = null;

// required by Hibernate
protected Persistable() {
super();
}

public final Long getKey() {
return key;
}

public final Timestamp getVersion() {
return version;
}

protected final void setKey(Long key) {
this.key = key;
}

protected final void setVersion(Timestamp version) {
this.version = version;
}

public abstract int hashCode();

public abstract boolean equals(Object o);

// .... other getter/setter methods removed ... //
}

public abstract class Person extends Persistable {
// ... person specific stuff ...//
}

public abstract class Parent extends Person {
// ... parent specific stuff ... //
}

public class Father extends Parent {
// ... father specific stuff ... //
}

public class Mother extends Parent {
// ... mother specific stuff ... //
}

<b>New Information:

I found that by removing the 'final' and creating methods inside the top persistence class, e.g. Person, I did not get the error. In fact, any class that extends this class does not get the error.

Modifications:

I added the following to Person:</b>

public Long getKey() {
return super.getKey();
}

public Timestamp getVersion() {
return super.getVersion();
}

protected void setKey(Long key) {
super.setKey(key);
}

protected void setVersion(Timestamp t) {
super.setVersion(t);
}

<b>These changes allowed Hibernate to configure properly; however, when I attempted to use I received the following exception:</b>
