Examples of javax.persistence.EntityManager.createNamedQuery()

javax.persistence.EntityManager.createNamedQuery()
Create an instance of Query for executing a named query (in EJB QL or native SQL). @param name the name of a query defined in metadata @return the new query instance @throws IllegalStateException if this EntityManager has been closed @throws IllegalArgumentException if a query has not beendefined with the given name
