SSLHandshakeException: No subject alternative names present

I am invoking HTTPS SOAP web service through java code. I have already imported self-signed certificate in jre cacerts keystore. Now I am getting :

com.sun.xml.internal.ws.com.client.ClientTransportException: HTTP transport error: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present

The hostname of the service URL is not matching that of the CN provided in cert. I read about a workaround of defining a custom Hostname verifier here. But i cant able to make where I should implement the workaround in my code.

public SOAPMessage invokeWS(WSBean bean) throws Exception {

    SOAPMessage response=null;
    try{

    /** Create a service and add at least one port to it. **/
    String targetNameSpace = bean.getTargetNameSpace();
    String endpointUrl = bean.getEndpointUrl();
    QName serviceName = new QName(targetNameSpace, bean.getServiceName());
    QName portName = new QName(targetNameSpace, bean.getPortName());
    String SOAPAction = bean.getSOAPAction();
    HashMap<String, String> map = bean.getParameters();


    Service service = Service.create(serviceName);
    service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointUrl);

    /** Create a Dispatch instance from a service. **/
    Dispatch dispatch = service.createDispatch(portName, SOAPMessage.class,
            Service.Mode.MESSAGE);

    // The soapActionUri is set here. otherwise we get a error on .net based
    // services.
    dispatch.getRequestContext().put(Dispatch.SOAPACTION_USE_PROPERTY,
            new Boolean(true));
    dispatch.getRequestContext().put(Dispatch.SOAPACTION_URI_PROPERTY,
            SOAPAction);

    /** Create SOAPMessage request. **/
    // compose a request message
    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage message = messageFactory.createMessage();

    // Create objects for the message parts
    SOAPPart soapPart = message.getSOAPPart();
    SOAPEnvelope envelope = soapPart.getEnvelope();
    SOAPBody body = envelope.getBody();

    SOAPElement bodyElement = body.addChildElement(bean.getInputMethod(),
            bean.getPrefix(), bean.getTargetNameSpace());

             ...more code to form soap body goes here

    // Print request
    message.writeTo(System.out);

    // Save the message
    message.saveChanges();

    response = (SOAPMessage)dispatch.invoke(message);
    }
    catch (Exception e) {
        log.error("Error in invokeSiebelWS :"+e);
    }
    return response;
}

Please ignore WSBean parameter as the namespaces and other wsdl attributes are coming from this bean. And if this exception can solved with some different workarounds, pls do suggest.
