verify detached signature

I would like to create a java web application which verify "XADES" signature, 
this application should take two files : the original file and his detached 
signature.

with XADES4j is there a way to verify signature without verifying the Reference 
for URI file ?  because the given reference File in xml signature could not be 
accessible.

What steps will reproduce the problem?
1. Produce signature with Reference uri which is not accessible
2. make the verifying using this code
CertificateValidationProvider certValidator = new 
CertificateValidationProviderImpl();
XadesVerificationProfile p = new XadesVerificationProfile(certValidator);
p.acceptUnknownProperties(true);
XadesVerifier v = p.newVerifier();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new 
FileInputStream("data_signed/detachedTestSignature.xml"));
XAdESVerificationResult vr = v.verify(doc.getDocumentElement(), null);

What is the expected output? 
An exception thrown, Exception in thread "main" xades4j.XAdES4jXMLSigException: 
Error verifying the signature....
Caused by: org.apache.xml.security.signature.MissingResourceFailureException: 
The Reference for URI 
file:/D:/workspace/xades4j-487d7a9bb9e5/data_to_sign/test.txt has no 
XMLSignatureInput
Original Exception was 
org.apache.xml.security.signature.ReferenceNotInitializedException:
