Need help getting NamedQuery to work. I am able to use other queries successfully.
Here is the exception I encounter:
createNamedQuery() returns:
[java] Exception in doTask()
[java] org.hibernate.MappingException: Named query not known: Movie.queryMoviesByStudio
[java] at org.hibernate.impl.SessionImpl.getNamedQuery(SessionImpl.java:963)
[java] at org.jboss.ejb3.entity.EntityManagerImpl.createNamedQuery(EntityManagerImpl.java:55)
[java] at com.demos.hibernatemovies.MovieBean.findMoviesByStudio(MovieBean.java:158)
Here are the key parts of my code.
In Movie.java:
@Entity
@NamedQueries(
@NamedQuery(
name="Movie.queryMoviesByStudio",
queryString="SELECT movie FROM Movie movie
WHERE movie.studioName = :studioName"
)
)
@Table(name="MOVIE")
public class Movie implements java.io.Serializable {
// etc.
}
In MovieInterface.java:
@Remote
public interface LoadMovieBeanInterface {
public void findMoviesByStudio(String studioName);
}
In MovieBean.java:
public void findMoviesByStudio(String studioName)
{
Query query = manager.createNamedQuery
("Movie.queryMoviesByStudio");
query.setParameter("studioName", studioName);
Collection movies = query.getResultList();
// etc.
}
Software levels:
J2SE 1.5.0
JBoss 4.0.1 SP1
EJB 3 Preview 5
I have looked at the Query folder in Hibernate-Annotations download bundle. The query there is package-level, while in my case it is class-level.
What have I overlooked?
Thanks to one and all for any help or suggestions.
