Alguem sabe o por que eu consigo cadastrar no banco com hibernate com esse código executando ele sozinho por dentro do eclipse:

public class Cadastrar {
public static void main(String[] args) {
Session session = new HibernateFactory().getSession();
Produto p = new Produto();
p.setNome(“Nome aqui”);
p.setDescricao(“Descrição aqui”);
p.setPreco(100.50);
session.save§;
session.close();

e utilizando o struts+hibernate e tomcat eu não consigo com esse???

public class CadastroAction extends Action{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest req,
HttpServletResponse res)throws Exception{

	Session session = new HibernateFactory().getSession();
	Produto produto = (Produto)form;
	new ProdutoDao(session).salva(produto);
	session.close();
	return mapping.findForward("sucesso");
}

}

e o Dao:

public class ProdutoDao {
private Session session;

public ProdutoDao (Session session){
	this.session = session;
}
public void salva (Produto produto){
	this.session.save(produto);
}
public void remove (Produto produto){
	this.session.delete(produto);
}
public Produto procura (Long id){
	return (Produto) this.session.load(Produto.class, id);
}
public void atualiza (Produto produto){
	this.session.update(produto);
}

}
