Pessoal,

Sou iniciante em Hibernate... estava tentando colocar para rodar o exemplo que vem no Hibernate Referente (Quick Start With Tomcat) e encontrei problemas... criei uma classe idêntica à que o tutorial mostra e tentei usá-la a partir de um jsp, como se segue:

Endereco e = new Endereco();

e.setEndereco("Rua Itajubá");
e.setNumero("150");
e.setComplemento("Apto 102");
e.setBairro("Jd Andere");
e.setCidade("Varginha");
e.setUf("MG");
e.setCep(37006400);
e.setTipo('C');

Session s = HibernateUtil.currentSession();
Transaction t = s.beginTransaction();
s.save(e);
t.commit();
HibernateUtil.closeSession();

Quando chamo a página dá o erro:

exception 

javax.servlet.ServletException
	org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:867)

No log encontrei:

O que há de errado?

Valeu.

Pessoal, o problema acima eu consegui resolver… faltava adicionar o jta.jar ao lib da minha aplicalção…

Agora estou com outro problema e já tô quase jogando a toalha…

O código jsp é o mesmo. Erro:

net.sf.hibernate.JDBCException: Could not save object net.sf.hibernate.impl.SessionImpl.saveWithGeneratedIdentifier(SessionImpl.java:744) net.sf.hibernate.impl.SessionImpl.save(SessionImpl.java:717) org.apache.jsp.jsp.teste.hbm_jsp._jspService(hbm_jsp.java:62) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:133) javax.servlet.http.HttpServlet.service(HttpServlet.java:856) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:311) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:301) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:248) javax.servlet.http.HttpServlet.service(HttpServlet.java:856)

E no log:

Esse tá bravo de resolver… já tô sem saber o que tentar…

Esqueci uma coisa: no script jsp eu já retirei o t.commit(), ficando dessa maneira:

Session s = HibernateUtil.currentSession();
s.save(e);
s.flush();
HibernateUtil.closeSession();

A classe HibernateUtil:

public class HibernateUtil {
    
    private static final SessionFactory sf;
    
    public static final ThreadLocal session = new ThreadLocal();
    
    static {
        try {
            sf = new Configuration().configure().buildSessionFactory();
        } catch (HibernateException he) {
            throw new RuntimeException("Exception building SessionFactory: " + he.getMessage());
        }
    }
    
    public static Session currentSession() throws HibernateException {
        Session s = (Session) session.get();
        if(s==null) {
            s = sf.openSession();
            session.set(s);
        }
        return s;
    }

    public static void closeSession() throws HibernateException {
        Session s = (Session) session.get();
        session.set(null);
        if(s!=null) s.close();
    }
}
