Your issue with the generics is you need to tell it that 'T extends
Indetifiable', or take it out entirely if you are going to explicitly tell
it that you are using the Parent class.
Also feel free to make the argument match what your load method requires.
The article could be referencing code that is old or whatever. Also keep in
mind that the class Long implements Serializable, but the primitive long
(lower case 'l') isn't an object and doesn't have a type inheritance (even
though it will serialize, but that's a disfferent topic).

public class EntityModel<T *extends Identifiable*> extends
AbstractEntityModel<T> {
public EntityModel(Class<? extends T> clazz, Serializable id) {
super(clazz, id);
}
@Override
protected T load(Class clazz, Serializable id) {
return WicketApplication.get().get_
service().load(clazz, id);
}
}
