@NamedQuery : does it have to be declared on an @Entity ?

[Sol Mayer-Orn]

I'm new to ejb, and trying to use @NamedQuery.
When you declare @NamedQuery (using annotations, not XML), do you have to declare it on an @Entity class ?

I mean:

// This works (on an Entity):
@NamedQuery(name=..., query=...)    
@Entity 
public class SomeEntity{
}
 
// But I couldn't get it to work when the class is 
// not an entity:
@NamedQuery(name=..., query=...)    
public class NotAnEntity{
}

I couldn't get the second example to work.
I even tried declaring the NotEntityClass in persistence.xml, but it didn't work - maybe I did it wrong ?
<class>somePackage.NotAnEntity<class>

Is there some way to make it work ?
Thank you.

Sol,
@NamedQuery does need to be declared on an @Entity class. As you noted, the alternative is to put it in XML.

As I recall, it goes in the orm.xml file. For example:

<named-query name = "findAllEntities">
  <query>select e from entity</query>
</named-query>
