Hi all,

Can anyone suggest whether it is possible to map the following class?
The problem is that I should have a default constructor (plus setters), which conflicts with java final keyword.

If you could point me to the relevant part in the doc, I would appreciate.

Thank you.

Code:

public class Question {
   
    private final String name;
    private final String value;

    public Question(String name, String value) {
        this.name = name;
        this.value = value;
    }
}

I think you would want to implement a UserType and store each field as a Hibernate.STRING. Check out documentation on custom value types:

http://www.hibernate.org/hib_docs/v3/re ... pes-custom

Creating your own user type is relatively easy with Hibernate. :)
