Java.lang.IllegalArgumentException: Named request not found. (Entity Manager does not create NamedQuery)

I am using hibernate 4.1.5. Final and Spring 3.1.2 Release and Jboss 7.1. I wrote all the named queries in the class with the @NamedQuery annotation, but the object manager does not create a named query. I am sending stacktrace and context.xml

I have written all named queries in a class with @NamedQuery annotation

Did you not clearly indicate the type of class you are talking about in the above statement? You will need to write named queries in the Entity class (the class annotated with the @Entity annotation).

UPDATE: DBNamedQuery. , . , . , @Entity DBNamedQuery, jpa?

, @NamedQuery, . , DBNamedQuery .

, , . , EntityManger API , contains(java.lang.Object entity).

, , JPA Named Queries jpa-. xml .

, , xml , Queries.hbm.xml, .

<?xml version="1.0" encoding="UTF-8"?>

Edit , , DAO-. like = >

public int executeNamedQuery(String namedQuery, String namedParams[], Object params[]) throws DatabaseException {
        int result = 0;
        Session session = getSession();
        final String methodName = "executeNamedQuery";
        try {
            session.beginTransaction();
            Query q = session.getNamedQuery(namedQuery);
            if (namedParams != null) {
                for (int i = 0; i < namedParams.length; i++) {
                    q.setParameter(namedParams[i], params[i]);
                }

            logger.debug("{} :: {} = {}", new Object[] { methodName, "No. of objects affected", result });
        } catch (HibernateException e) {

            final String message = "Couldn't execute the named query " + namedQuery;
            logger.error("{} :: {}", new Object[] { methodName, message, e });

        } finally {
            closeSession();
        }
        return result;
    }

: 1) namedQuery Queries.hbm.xml.     2) namedParams [] Query.     3) params .

, DBNamedQuery com.project.entities, ApplicationContext.xml

, - . , @NamedQuery, , .

@NamedQuery(name = "AAAA", query = ... ) //must be same the name which call that query

public void some() {
   Query q = em.createNamedQuery("AAAA");
 }

persistence.xml

<property name="hibernate.archive.autodetection" value="class, hbm" />

, , didnt work

  @Bean

           LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
           em.setDataSource(getDataSource());

           em.setPersistenceUnitName(PERSISTENCE_UNIT_NAME);
           em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
           return em;
