我有一个类User，它位于持久性单元idmalight中。我必须创建一个扩展用户的类CMNUser，但必须使用持久性单元cmn。
首先，有可能吗？
如果是，这里是类的片段：
@Entity
@Audited
@Table( name = "NETHZ_USER" )
@Inheritance( strategy = InheritanceType.JOINED )
public class User extends PersistentObject
{
fields
getters
setters
}
@Entity
@Table( name = "CMN_USER" )
@Inheritance( strategy = InheritanceType.SINGLE_TABLE )
public class CMNUser extends User
{
@ManyToMany( fetch = FetchType.LAZY )
@JoinTable( name = "CMN_MAP_USER_TO_DELEGATE" )
private Set< User > delegates;
getter
setter
}
当我尝试部署应用程序时，我收到错误：

权限在User class中定义为
@ManyToMany
private Set< Permission > permissions;
这是因为不同的PU和实体CMNUser不知道父类中设置的字段（因此不可能做这样的事情）或者还有其他原因吗？
