If a POJO has multiple set() methods for the same property (with different signatures, of course), which one does Hibernate use?

I have set up a mapping and the following works just fine:



However, I get an Exception when I add a second set method, such as:

It seems like whenever I have two setters with different signatures for the same property, I get an exception. I have tried various combinations of property types and set methods, and it seems that my basic problem is that two setters on the same property generates an exception.

Is there a way that I can persuade Hibernate to use the correct setter and ignore the others?

Thanks,
Dave
