Não sei pq ta dando esse erro, pois ja olhei meu código várias vezes, e somente o primeiro exemplo da apostilha CAELUM, funcionou no meu projeto do "Alo mundo Spring", já esse do formulario a página não é encontrada, porfavor alguem me ajuda ai, para continuar estudando.
Obs.: na lib tem todos os jar. solicitados pela apostilha da Caelum.
