Thanks for your response, but I allready tried to solve it with a many-to-one mapping, but Hibernate still gives the following error:
Code:

I have the following sheme:
Abstract class SyntaxComponent;
2 subclasses:
Class Rule extends SyntaxComponent;
Class Operation extends SyntaxComponent;And the subclass '
Rule' has an '
Operation' member value. And this gives the problems!
class Rule extends SyntaxComponent {
private Operation op;
...
}
I posted my mapping file below.
