Olá amigos depois de tanto sofrer, consegui inserir dados no meu bd com jsf e primefaces.
Só que o que me assustou foi a quantidade de mensagens no console.

OK.Graças à Deus e Nossa Senhora!!!
Em algum lugar diz ERRO: valor nulo na coluna "pais_descricao" viola a restrição não-nula.
Mas eu verifiquei no banco e o campo pais_descricao está preenchido, ou seja, não está nulo.
O que pode ser esta enxurrada de mensagens :?:
