Posting a SOAP XML to an SSL

Question

When I try to post the XML to an SSL link by the following code

public void send(String url, String xmldoc)
 {

  StringBuffer sb = new StringBuffer();
  try
  {

   ByteArrayInputStream bais = new ByteArrayInputStream(xmldoc
     .getBytes());  
   InputSource is = new InputSource(bais);
   DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
   factory.setNamespaceAware(true);  
   DocumentBuilder builder = factory.newDocumentBuilder();  
   Document document = builder.parse(is);
   org.w3c.dom.Element root = document.getDocumentElement();
   org.apache.axis.message.SOAPBodyElement input[] =
   {
    new org.apache.axis.message.SOAPBodyElement(root)
   };  
   Service service = new Service();  
   org.apache.axis.client.Call call = (Call) service.createCall();  
   call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
   call.setTimeout(new Integer(0x2bf20));
   call.setTargetEndpointAddress(new URL(url));
   call.setOperationStyle("document");
   Vector result = null;
   result = (Vector) call.invoke(input);  
   SOAPBodyElement body = (SOAPBodyElement) result.elementAt(0);   

  }
  catch (Exception e)
  {
   e.printStackTrace();
  }
 }

I get this exception
