Pessoal, fiz esse metodo para retornar nomes que iniciam com o que for preenchido na variável "nome". ( a consulta está certa?)
Só que está retornando o erro abaixo.
public List<Estoque> consultaAlternativa(String nome){
EntityManager em = getEntityManager();
Query q = em.createQuery("Select e from estoque e WHERE e.nome like'"+ nome +"%'");
return (List<Estoque>) q.getResultList();
}
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager:
Exception Description: Error compiling the query [Select e from estoque e WHERE e.nome like'on%']. Unknown entity type [estoque].
