I'm trying to retrieve data from a stored procedure.
It works fine when the SP hasn't parameters but I can't make it work for an SP that do have them.
I think that the problem may be that the default NamedNativeQuery annotation doesn't support the callable attribute and the hibernate-anotation.jar included in the jboss-4.0.3RC2 does not include org.hibernate.annotations.NamedNativeQuery which supports it.
Can anyone tell if this is the problem ?

More info

* Stateless Bean

This works

public Collection getSP() {
Query q = em.createNativeQuery("sp_fund", "getFunds");
return q.getResultList() ;
}

this doesn't

public Collection getSP2() {
// I've tried multiple forms of the next two lines
Query q = em.createNativeQuery("sp_fund2(?)", "getFunds");
q.setParameter(0, 1) ;
return q.getResultList() ;
}

* Entity Bean Annotation

@SqlResultSetMapping(
name="getFunds", entities =
@EntityResult(name="entity.beans.Fund", fields= {
@FieldResult(name="id", column="id"),
@FieldResult(name="name", column="name"),
@FieldResult(name="growthrate", column="growthrate")
}
)
)
