Hibernate Unknown integral data type for ids

Question

I\'m starting with Hibernate and I have an error that I just can\'t figure out.

I have the following Classes:

@Entity
@Inheritance(strategy = Inherit

If you want String to be database key you need to use UUID to automatically generate key. Something like this:

@Id @GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
private String myId;
