Esta ocorrendo é que quando deixo algum campo vazio ele esta me retornando este erro: Formulario: [code] <html:form action="/cadastroFisico1" method="post" enctype="multipart/form-data"> <html:hidden…

por isso q eu não gosto de tipo primitivo… vc não pode fazer o parse na String vazia…se vc realmente vai manter seus atributos como tipos primitivos…trate eles antes, verifica se são diferentes de nulo e vazio. espero ter ajudado…

cara valida isso no ActionForm…

Coloca no struts-config.xml validate=true e depois fica fazendo a verificação no metodo validate do ActionForm
