In a domain class, a pair of fields as



The validation logic shall be a non-zero value in saleTax when saleTaxName is not blank and the saleTaxName field isn't blank when the saleTax is bigger than zero. Otherwise, saleTaxName is blank and saleTax is zero. How to express this validation logic with the Hibernate validator?

A custom class level constraint would be your best bet. In this case you get the whole domain object passed into the validation method and you can do any cross checks you like. Check the online docs for that - http://docs.jboss.org/hibernate/stable/ ... ml_single/

I have a simmilar problem. The validation depends on an additional parameter or field.
We have different Customers they can be generated dynamically together with an profile (this is stored in the DB). depending on this value the Validation is different.
Validations on the hole Object is a very bad Option. Can we do validations with a given Parameter?

What do you mean with "validation with a given parameter". How would this look like in your opinion?

--Hardy

if you call the validation method you might pass over an additional parameter like this:

validator.validate (objectToFactor, parameter);

this parameter might be the customer in our case. But this is just a suggestion.
