Hibernate version: 3

<class name="UserProfile" table="user_profile">
<id name="userid" column="userid" type="java.lang.Short">
<generator class="native"/>
</id>


In the original design, the data structure does not have a id field.
In order to compromize with Hibernate, a userid field is introduced.
It works fine with Struts.

I wonder if I can have a composite fields which composes of two string fields. If I can, how can I define it in ???.hbm.xml?

Thanks

it is very simple for hibernate . There is a solution about the composit-id
you can read the document about hibernate composite-id.
i reference a bit from the hibernate document :
