    Default sign XML with WS-Security

    Hello,
    I'm new to this forum but i need some help.
    My problem is for signing a xml with the WS-Security Oasis specification
    (it's: <wsse:security><ds:signature><ds....)
    Actually i use the xws-security framework but i have a bug, look my code:
    // Initialize the apache libraries
    Init.init();
     
    // Obtain security elements from the keystore
    PrivateKey privateKey = keyEntry.getPrivateKey();
     
    // Obtain a sample SOAPMessage from a file
    FileInputStream fis = new FileInputStream(new File(fileName));
    Document doc = XMLUtil.toDOMDocument(fis);
    //SOAPMessage message = MyFileUtils.getMessageFromFile(doc);
    MessageFactory fac = MessageFactory.newInstance();
    MimeHeaders mimeHeaders = new MimeHeaders();
    mimeHeaders.addHeader("Context-Value", null);
    SOAPMessage message = fac.createMessage(mimeHeaders, new FileInputStream(fileName));
    SOAPHeader header = message.getSOAPHeader();
    SOAPBody body = message.getSOAPBody();
     
     
    // Set the wsu:Id attribute to the Body
    XMLUtil.setWsuIdAttr(body, "id-2");
     
     
    // Create a WSSE context for the SOAP message
    SecurableSoapMessage sssm = new SecurableSoapMessage(message);
     
     
    // Create a security header for the message (<wsse:Security>)
    SecurityHeader sh = sssm.findOrCreateSecurityHeader();
     
     
    // Insert the certificate (<wsse:BinarySecurityToken>)
    X509SecurityToken stoken = new X509SecurityToken(header.getOwnerDocument(), cert);
     
    // Insert the keyinfo referring to the certificate (<ds:KeyInfo>)
    KeyInfoHeaderBlock kihb = new KeyInfoHeaderBlock(header.getOwnerDocument());
    SecurityTokenReference secTR = new SecurityTokenReference(header.getOwnerDocument());
    kihb.addBinarySecret(stoken.getAsSoapElement());
    sh.insertHeaderBlock(kihb);
     
     
    // Insert the Signature block (<ds:Signature>)
    SignatureHeaderBlock shb = new SignatureHeaderBlock(header.getOwnerDocument(),XMLSignature.ALGO_ID_SIGNATURE_RSA);
    Transforms transforms = new Transforms(header.getOwnerDocument());
    transforms.addTransform(CanonicalizationMethod.EXCLUSIVE);
     
     
    shb.addSignedInfoReference("id-2", transforms, Constants.ALGO_ID_DIGEST_SHA1);
    sh.insertHeaderBlock(shb);
     
     
    // Digest all References (#MyId) in the SignedInfo, calculate the signature value
    // and set it in the SignatureValue Element
    javax.swing.JOptionPane.showMessageDialog(null, "PublicKey : "+privateKey.toString());
    shb.sign(privateKey);
     
    // Add the signature data to the header element
    header.addChildElement(sh.getAsSoapElement());
     
     
    // Save the signed SOAP message
    FileOutputStream fos = new FileOutputStream(new File(signatureFileName));
    message.writeTo(fos);
    message.writeTo(System.out);

    This code return a null exception at the line : shb.sign(privateKey)
    Erreur code:
    An error has occurred : java.lang.NullPointerException
