How to validate soap signature using wss4j library

Question

I have a soap message as below

How can I verify the message signature using wss4j.? I want to do it in a java program and not in any framework like axis or cxf.

WsSecurityException will be thrown if signature is not corresponding to message.

public void processSoapSecurityHeader(String soapRequest, String keyStore, String keyStorePwd, String alias) throws Exception {

    SOAPMessage soapMessage = MessageFactory.newInstance().createMessage(null, new  ByteArrayInputStream(soapRequest.getBytes()));
    FileInputStream is = new FileInputStream(keyStore);
    KeyPair keypair = null;
    KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
    keystore.load(is, keyStorePwd.toCharArray());
    Certificate cert = null;
    Key key = keystore.getKey(alias, keyStorePwd.toCharArray());
    if (key instanceof PrivateKey) {
      cert = keystore.getCertificate(alias);
      PublicKey publicKey = cert.getPublicKey();
      keypair = new KeyPair(publicKey, (PrivateKey) key);
    }
     Properties properties = new Properties();
     properties.setProperty("org.apache.ws.security.crypto.provider", "org.apache.ws.security.components.crypto.Merlin");
     Crypto crypto = CryptoFactory.getInstance(properties);
     keystore.setKeyEntry(alias, keypair.getPrivate(), keyStorePwd.toCharArray(), new Certificate[]{cert});
     ((Merlin) crypto).setKeyStore(keystore);
     crypto.loadCertificate(new ByteArrayInputStream(cert.getEncoded()));
     WSSecurityEngine engine = new WSSecurityEngine();
     WSSConfig config = WSSConfig.getNewInstance();
     config.setWsiBSPCompliant(false);
     engine.setWssConfig(config);
     List<WSSecurityEngineResult> res = engine.processSecurityHeader(toDocument(soapMessage), null, null, crypto);
     for (WSSecurityEngineResult ers : res) {
           LOG.trace("Details of security header after validation {}" , ers.toString());
     }
     LOG.debug("Validation code executed");
}
