java - Named query on a Mapped Superclass -

i'm trying declare namedquery on mapped superclass, obtain error:

org.hibernate.hql.ast.querysyntaxexception: voipcall not mapped [select v voipcall v v.audiofile = :audiofile]

we use hibernate, prefer use jpa standard notation.

here code:

@mappedsuperclass @namedqueries(value = {     @namedquery(name = "getvoipcallsforaudio", query = "select v voipcall v v.audiofile = :audiofile") }) public abstract class voipcall implements serializable { 

it seems cannot use mappedsuperclass in query, don't understand why if in jpa api found this:

the namedquery annotation can applied entity or mapped superclass.

where wrong?

thanks!!

solution: solution me workaround: moved named query on subclasses changing clause opportunely. point of view give me less maintainability of code, cannot in way.

it fine have @namequery annotation in @mappedsuperclass. in past hibernate used had issue hhh-4364, caused fail. issue fixed since years.

on other hand query not expected work, because mapped superclass cannot queried. in jpa 2.0 specification told following words:

a mapped superclass, unlike entity, not queryable , must not passed argument entitymanager or query operations.

this restriction kind of makes sense - purpose of mapped superclass share mappings between otherwise non-related entities, mapped superclass not supposed root of entity inheritance hierarchy. if such query works, purely because of jpa vendor specific extension.
