Here is the problem: my persistent classes are JavaBeans style classes which use the JavaBean veto mechanism to control properties changes. So, most of the setters throws a PropertyVetoException...
Will that be a problem for hibernate? The documentation talks about the visibility of the methods (protected, private, ...) but nothing about Exceptions...

If it represents a problem, how to handle that?

Thanks...

There shouldn't be any.

Okay thanks :)

But i'm still wondering what will append if hibernate try to set an unvalid property value (eg null).

I have a terrible doubt: did you mean "there shouldn't be any exception" or "there shouldn't be any problem"?

Hibernate will just pass on the RuntimeException, but it probably won't set any invalid value (it will set the value of the database field, of course).

Ok thx :)
