Na boa? Evita colocar esse monte de código. Dá até desanimo de ler… =/

Não precisa ficar com medo de ler a mensagem de erro. Ela apontou nullpointer na linha:
at br.net.sores.bean.UsuarioBean.salvar(UsuarioBean.java:60)

Tem algum cara nessa linha que está null. Quem é? [=

Oi jakefrog blz,entao tinha visto que o problema e na hora de enviar os dados ao Salvar, pelo que vi eu preencho os campos clico no botao pra salvar mas nao vai dado nenhum, tudo fica em branco, nao to sabendo como resolver essa passagem dos dados que foram digitados para a execucao do metodo

O problema é que você está instanciando um novo usuário dentro do método salvar e ainda verificando a senha de uma variável local. São valores novos, não são os mesmos que estão sendo digitados pelo usuario. O certo é instanciar fora do método(num método com anotação @PostConstruct por exemplo) e no método só fazer o que o método deve fazer.

ErickRAR, vlws mesmoooo , nem precisei usar o @PostConstruct, so tirei a linha que instanciava a classe usuario de dentro do metodo SALVAR dai funcionou.
