E o seguinte e consigo enviar um formulario via ajax tipo
jQuery.fn.adicionaPessoa = function(){
jQuery.ajax({
contentType: “application/x-www-form-urlencoded”,
async: true,
type: “POST”,
url: “cadpesssoa.adiciona.logic”,
data: (jQuery(’#formulario’).serialize()),
});
}
Isso ai em cima funciona blz.
Agora seu eu quiser usar o FileUpload como manda na documentacao no VRaptor ENCTYPE=“multipart/form-data”
o codigo ficaria assim
jQuery.fn.adicionaPessoa = function(){
jQuery.ajax({
contentType: “multipart/form-data”,
async: true,
type: “POST”,
url: “cadpesssoa.adiciona.logic”,
data: (jQuery(’#formulario’).serialize()),
});
}
tenho a seguinte exception:
java.lang.NullPointerException
