Pessoal,

Fiz um pequeno projeto , e neste projeto esta dando o erro nesta linha

ocorrenciasdao dao = new ocorrenciasdao();
		String vocorrencia1 = getRequest().getParameter("combo");
		name_ocorrencias no = dao.getidnameocorrencia1(Integer.parseInt(vocorrencia1));


public class ocorrenciasdao extends DAO<ocorrencias>{

public name_ocorrencias getidnameocorrencia1(int nro) throws DAOException {
	Query q = query("select id FROM name_ocorrencias o where o.id =:pnro ");	
	q.setParameter("pnro", nro);

	List<name_ocorrencias> results = q.list();
	name_ocorrencias no = results.get(0);
	return no;		
	}

}

OBS. : O valor do getRequest().getParameter(“combo”) é 1.

Segue abaixo o erro completo :

você está buscando somente o ID e não o objeto inteiro, então quando tenta fazer o casting, você tem uma lista de Integer, e não do objeto que quer, tente mudar a query buscando pelo alias o ao invés de id

evandro_araujo 18 de set. de 2012

Tentei colocar da seguinte forma e o erro continua :

public name_ocorrencias getidnameocorrencia1(int nro) throws DAOException {
	Query q = query("select o FROM name_ocorrencias o where o.id =:pnro ");	
	q.setParameter("pnro", nro);

	List<name_ocorrencias> results = q.list();
	name_ocorrencias no = results.get(0);
	return no;		
	}

}

Evandro,

já tentou fazer o cast na linha 7?

provavelmente nesta parte do código que está dando a excessão:

name_ocorrencias no = results.get(0);

Faça da seguinte forma:

name_ocorrencias no = (name_ocorrencias) results.get(0);

evandro_araujo 18 de set. de 2012

Tentei colocar dessa forma :

public name_ocorrencias getidnameocorrencia1(int nro) throws DAOException {
	Query q = query("select o FROM name_ocorrencias o where o.id =:pnro ");	
	q.setParameter("pnro", nro);

	List<name_ocorrencias> results = q.list();
	name_ocorrencias no = (name_ocorrencias)  results.get(0);
	return no;		
	}

}

coloca sua entidade name_ocorrencias aqui

evandro_araujo 18 de set. de 2012

package intranet.entity;

public class name_ocorrencias {
	
	private Integer id;
	private String nome;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getNome() {
		return nome;
	}
	public void setNome(String nome) {
		this.nome = nome;
	} 

}
