discriminator with type"int"

Does Hibernate Support it correctly ? Because i've been searching the web for examples and even in the hibernate's site I haven't found nothing with the int type, all example uses string type...

I tried this in my table per class mapping XML file....

Code:

 <discriminator   column="code" type="int" />

...

<subclass     name="MySubClass" extends="MyParentClass"   discriminator-value="1" >
                    <property name="..."    column="..." />
                    <property name="..."     column="..."/>
</subclass>

for no success, the stack trace shows this error:

org.hibernate.MappingException: Could not format discriminator value to SQL string

i've changed the database to varchar and the <discriminator-value> to a string value (like CARD,CHECK).... and used type="string" and everything was fine.....but when i try to use int (making the necessary changes of course) this error occurs....

can somebody give me tip or clue???
Thanks in advance!!

It works for us, altough we use Integer, not int.

Yes. Hibernate supports for int. Use Integer inside the POJO as hutorny suggested.

It is best practice to use object rather than primitive inside the POJO for property types.
