paribe

Olá ,

não estou visualizando por que está fechando a sessão …
quando executo na sequência a busca ao DAO a primeira executa a segunda não…conforme abaixo.

alguém já passou por essa situação e poderia me ajudar …abs

codigo metodo chama DAO

// primeiroa busca no DAO busca o nome do instituto
        InstitutoRN irn = new InstitutoRN();
        
        Object[] in = irn.buscar();
        if (in== null){
        	nome="Instituto não cadastrado";
        }else{
        	@SuppressWarnings("unused")
			BigInteger id= (BigInteger) in[0];
            nome= (String) in[1];
        }
        // segunda busca no banco inicio busca qtde de aluno
        try {
        	BigInteger in1 = irn.getCountAluno();
            if (in1==null){
            	qtdeAluno =  BigInteger.valueOf(0);
            }else{
            	 qtdeAluno= (BigInteger) in1;
            }	
		} catch (Exception e) {
			long valor =0;
        	qtdeAluno =  BigInteger.valueOf(valor);
		}
        //fim busca qtde de aluno
		
		System.out.println("qtdealuno="+qtdeAluno+"");
		parametrosRelatorio.put("INSTITUTO", nome);
		parametrosRelatorio.put("QTDEALUNO", qtdeAluno.toString());

DAO

public class InstitutoDAOHibernate implements InstitutoDAO {
    private Session session;
	public Session getSession() {
		return session;
	}

	public void setSession(Session session) {
		this.session = session;
	}

	public Object[] buscar() {

		Object[] instituto = null;
		String hql = "";

		try {
			this.session.beginTransaction().begin();
			hql = "SELECT * FROM instituto LIMIT 1";
			Query query = (Query) this.session.createSQLQuery(hql.toString());
			instituto = (Object[]) query.uniqueResult();
			this.session.beginTransaction().commit();
		} catch (Exception e) {
			System.out.println("Erro: " + e);
		}
		return instituto;
	}

	@Override
	public BigInteger getCountAluno() {
		BigInteger retorno = null;
		String hql = "";
		try {
			this.session.beginTransaction().begin();
			hql = "select count(distinct(nm_aluno)) from resposta_aluno";
			Query query = (Query) this.session.createSQLQuery(hql);
			retorno = (BigInteger) query.uniqueResult();
			this.session.beginTransaction().commit();
		} catch (Exception e) {
			System.out.println("Erro  " + e);
		}
		return retorno;
	}

Olá,

estou com um problema pois tinha dois metodos em um DAO e qdo chamava executava o primeiro
e o segundo dava o erro conforme topico http://www.guj.com.br/posts/reply/0/239397.java

o que fiz agora unifiquei em um só metodo mais agora tenho problema em jogar o 3 elemento no array

pois o primeiro sql gera dois campo em [0] e [1] e tento executar o sql e gera um elemento e coloco na
String de array como 3 elemento e me apresenta o erro…

se alguém puder me ajudar …
