I'm trying to use a @SecondaryTable, and I think I've tried every possible variant.
The table SettingType has a field named typeId which points to UserSetting.id.
There are other classes inheriting from UserSetting, but I've removed them to make sure they weren't causing this.

@Entity ( access = AccessType.FIELD )
@Table ( name = "PersonSetting" )
@SecondaryTables({
@SecondaryTable (
name="SettingType",
join={
@JoinColumn(
name="id",
referencedColumnName="typeId" )
}
)
})
public class UserSetting {
@Id
private int id;
@Column(secondaryTable="SettingType")
private String type;
@Column(secondaryTable="SettingType")
private String name;
@ManyToOne
@JoinColumn ( name="personId" )
private User user;

public int getId (){
return id;
}

public String getName (){
return name;
}

public String getValueType (){
return type;
}

public User getUser (){
return user;
}
}

Hibernate version: 3.1rc1, annotations 3.1b5

I've fix this NPE in a cleaner exception. But referencedColumnName="typeId" is illegal here, first typeId does not exist, second join columns on a non primary column for secodnary table is not supported
