Tenho um form em uma jsp simples, que envia nome e idade para um servlet, ai eu quero que ele passe o nome e a idade para outro servlet, entao eu uso o
reques.setAtribute("nome2", nome);
reques.setAtribute("idade2", idade);
Mas quando eu tento pegar no outro servlet esses dados usando o
request.getAtribute("nome2");
request.getAtribute("idade2");[/code]
eles vem como nulo.
Segue as minhas classes:

} finally {
out.close();
