Pessoal,

Boa tarde, estou com um problema para utilizar o VRaptor para fazer UpLoad de Arquivos, deve ser uma bobagem, mas como sou novato na ferramente não sei mais o que fazer.

@Post  
    public void gravarEvidencia(EvidenceModel model,UploadedFile file){  
        ExecutionBO bo = new ExecutionBOImpl();  
        try{  
              
            model.setFileBlob(IOUtils.toByteArray(file.getFile()));  
            bo.saveEvidence(model);  
              
            result.redirectTo("index/evidencia?model.id=" + model.getBuild().getId());  
              
        }catch (BOException e){  
            e.printStackTrace();  
        } catch (IOException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }     
    }

Ao realizar o submit recebo a seguinte exceção:

Pessoal,

         Problema resolvido, era o nome do meu objeto file no jsp que precisava ter o mesmo nome que coloquei como parâmetro no método.

Sem mais,
Cássio
