Digitale XML-Signatur Java

brauche ich, um digital signieren meiner XML-Nachrichten in JAVA:
Die resultierende XML-Signatur muss das folgende format haben:

<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
<SignedInfo>
<CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" />
<SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" />
<Reference URI="">
<Transforms>
<Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/>
</Transforms>
<DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256" />
<DigestValue>DsP5NLca+plhp9tZvGwykfb2whQYt3CQ5sbsVd9Q9aE=</DigestValue>
</Reference>
</SignedInfo>
<SignatureValue>
LrfE0po3YPvVxB/m77iBWWiR07Ghiuhuj7tO2C2LKqZK2cLrAiidt+3tjbJ3m16quCFxfh7bmjRtJsGi7a3HKtK
qY4auqrjNB62AtYrxvm+7Qd/cRacom4e3M9uF9JD1zTfoGun9w4WDfDrDaoZ+ZwUgNtf6sTYO5Ctcj5sYcD0=
</SignatureValue>
<KeyInfo>
<KeyName>7D665C81ABBE1A7D0E525BFC171F04D276F07BF2</KeyName>
</KeyInfo>
</Signature>

Kann jemand etwas Hilfe mit code ??

Edit:

kam ich mit diesem code :

private static Document sign(Document doc) throws InstantiationException, IllegalAccessException, ClassNotFoundException,
            NoSuchAlgorithmException, InvalidAlgorithmParameterException, KeyException, MarshalException, XMLSignatureException,
            FileNotFoundException, TransformerException {

        String providerName = System.getProperty("jsr105Provider", "org.jcp.xml.dsig.internal.dom.XMLDSigRI");

        XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM", (Provider) Class.forName(providerName).newInstance());

        Reference ref = fac.newReference("", fac.newDigestMethod(DigestMethod.SHA256, null));

        //Create the SignedInfo
        SignedInfo si = fac.newSignedInfo(
                fac.newCanonicalizationMethod(CanonicalizationMethod.EXCLUSIVE, (C14NMethodParameterSpec) null),
                fac.newSignatureMethod(SignatureMethod.RSA_SHA1, null), Collections.singletonList(ref));

        KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA");
        kpg.initialize(512);
        KeyPair kp = kpg.generateKeyPair();

        KeyInfoFactory kif = fac.getKeyInfoFactory();
        KeyValue kv = kif.newKeyValue(kp.getPublic());

        KeyInfo ki = kif.newKeyInfo(Collections.singletonList(kv));

        DOMSignContext dsc = new DOMSignContext(kp.getPrivate(), doc.getDocumentElement());

        XMLSignature signature = fac.newXMLSignature(si, ki);
        signature.sign(dsc);

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer trans = tf.newTransformer();
        trans.transform(new DOMSource(doc), new StreamResult(new FileOutputStream("mySignedFile")));

        return doc;
    }

aber das Problem ist, ich bin immer :

<SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/>

und nicht :

<SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" />
