Pessoal, minha chamada:

***************************Minha chamada
		PrecoPorMetodoBean osb = new PrecoPorMetodoBean();
		List<PrecoPorMetodo> resultado1 = osb.selecionaprecopormetodo(metodo.getId().toString());

*********************************************************************

estou tentando efetuar o select abaixo :

       	   EntityManagerFactory factory= Persistence.createEntityManagerFactory("lims-pu");
     	   EntityManager manager= factory.createEntityManager();

         	StringBuffer sbQuery = new StringBuffer();		
			sbQuery.append("select p from PrecoPorMetodo p ");
		
			Query query = manager.createQuery(sbQuery.toString());
			return query.getResultList();

erro abaixo :
javax.persistence.PersistenceException: org.hibernate.AnnotationException: @OneToOne or @ManyToOne on br.com.cqa.lims.orcamento.PrecoPorMetodo.metodo references an unknown entity: br.com.cqa.lims.analise.Metodo

Segue abaixo as minhas classes

1 - a importação de @Entity na classe está correta?
2 - Onde está o atributo anotado com @Id ?

#3

Rodrigo o @id esta aqui

public class PrecoPorMetodo extends Entidade{
#4

[quote=evandro_araujo]Rodrigo o @id esta aqui

[code]
public class PrecoPorMetodo extends Entidade{

[/code][/quote]
Aonde?
