Validação de Assinatura Digital

JavaC Membro Membro desde: 28/02/2014 10:11:26 Mensagens: 2 Offline

Estou realizando o processo de validação de assinatura digital no lado do servidor, recebendo um Lote deRPS. No momento da validação da assinatura do Lote de RPS a seguinte mensagem é apresentada. "javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.URIReferenceException: [com.sun.org.apache.xml.internal.security.utils.resolver.ResourceResolverException: Cannot resolve element with ID lote3936"

Segue código

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();  
    dbf.setNamespaceAware(true);  
    org.w3c.dom.Document doc = dbf.newDocumentBuilder().parse(  
            new InputSource(new StringReader(xml)));  
  
    NodeList xmlAssinatura = doc.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");  
    if (xmlAssinatura.getLength() == 0) {  
        throw new ValidateServiceException("Elemento Signature não encontrado");  
    }  
    DOMStructure dse = new DOMStructure(xmlAssinatura.item(1));  
    XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");  
    XMLSignature signature = factory.unmarshalXMLSignature(dse);  
  
    PublicKey publicKey = null;  
    List list = signature.getKeyInfo().getContent();  
    for (int i = 0; i < list.size(); i++) {  
        XMLStructure xs = (XMLStructure) list.get(i);  
        if (xs instanceof X509Data) {  
            for (Object data : ((X509Data) xs).getContent()) {  
                if (data instanceof java.security.cert.X509Certificate) {  
                    publicKey = ((java.security.cert.X509Certificate) data).getPublicKey();  
                }  
            }  
        }  
    }  
  
    DOMValidateContext valContext = new DOMValidateContext(publicKey, xmlAssinatura.item(1));  
    XMLSignature xmlSignature = factory.unmarshalXMLSignature(valContext);  
  
    System.out.println("|- coreValidity" + xmlSignature.validate(valContext));  
    System.out.println("|- signature validation status:"  
            + signature.getSignatureValue().validate(valContext));  
  
    Iterator i = xmlSignature.getSignedInfo().getReferences().iterator();  
    for (int j = 0; i.hasNext(); j++) {  
        Reference reference = ((Reference) i.next());  
        boolean refValid = reference.validate(valContext);  
        System.out.println("ref[" + j + "] validity status: " + refValid);  
    }  
  
    System.out.println("| Algoritmo assinatura: "  
            + signature.getSignedInfo().getSignatureMethod().getAlgorithm());  
    System.out.println("| Algoritmo do certificado: " + publicKey.getAlgorithm());
