Estou tendo problemas com uma servlet que tenta inserir um contato no Banco de Dados. O erro é o seguinte:
[code]com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

Fiz uma classe de testes que faz a mesma coisa e insere blz. No Windows XP a servlet funciona e o contato é inserido. O problema está sendo no Windows 7 mesmo. Já desabilitei firewalls/antivirus e não resolveu.
O código da classe de testes (que é o mesmo da servlet) é este:
[code] public static void main(String[] args) {
ContatoBean contato = new ContatoBean();
contato.setNome(“Fulano de Tal”);
contato.setTelefone("(99) 9999-9999");
contato.setEndereco(“Av. Principal, n.999 Centro”);
Session session = HibernateUtil.getSession();
try {
ContatoDAO dao = new ContatoDAO(session);
dao.inserir(contato);
} catch (Exception e) {
e.printStackTrace();
}
}[/code]
Não sei se a utilização do hibernate influencia. Gostaria de saber como faço para resolver este problema de permissão…
Vlw.
