title: Java preemptive authenticated webservice consumption using CXF
body: <p>I would like to consume a webservice which is secured using CXF. (http://host:port/test/ws?wsdl). Below is my code. but it is giving the exception given below.  In SoapUI i have tested the webservice. I have given credentials in SoapUI under "aut" tab. It was working.
  Could you please tell how to consume secured webservice using CXF?</p>
  
  <pre><code>ProcessService proxy = new ProcessService(wsdlURL, SERVICE_NAME);       
  try {       
    IProcessService port = proxy.getBinding1IProcessService();
    Client client = ClientProxy.getClient(port);
    HTTPConduit http = (HTTPConduit) client.getConduit();
    http.getAuthorization().setUserName("username");
    http.getAuthorization().setPassword("password");
  
  
    System.out.println("Result=" + port.startReturnDDCStatusForAC(""));
  } catch (Exception e) {
   e.printStackTrace();
  }
