"Named query not known" for named Hibernate query?

What might be the problem?

@Entity
@NamedQueries( {
    @NamedQuery(name = User.ALL,
                query = "SELECT u FROM User u")
})

public class User {
    public static final String ALL = "User.all";
}

public class Service {
    find... with ... User.ALL
}

Stacktrace:

I had similar issue when I renamed an Entity class in my package. Make sure the full class name for the persistence unit in the persistence.xml matches your Entity class. e.g.

   <persistence-unit name="your_PU_name" transaction-type="JTA">
      ...
      <class> [ make sure here is the FQN of your entity class ] </class>
      ...
   </persistence-unit>

Not sure if this will be your issue but check out this post here.

The issue was the use of:

org.hibernate.annotations.Entity

Instead of:

javax.persistence.Entity
