* Hibernate version: 3.1 *
* Annotations version: 3.1beta6 *

I have a table with two columns which are both part of a composite key, it is infact a join table. I didn't know know how to define the primary key except creating a different id-class (which will look the same like the first class - same properties, same methods), so I tried this:

@IdClass(MyClass.class)
public class MyClass implements Serializable {
...
}


And it's working. Is it ok to use @IdClass on self in situations like this or is there another preferable way?

Thank you.

never tried, give it a try.
Anyway the proper answer is for me to sit and implement the
<composite-id> equivalent in annotation. That's probably trivial, but I'm missing time and motivation

Hi petr82,

when I read the paragraph "Mapping composite primary and foreign keys" in the HA-documentation I thought the same.
But with the newest HA-release (3.2.0GA) it does not work. Instead I get a AnnotationException ("... has no persistent id property").
Would you mind pasting all your code here?
