Connect P6 Webservice from Java

I am trying to connect to P6 web service from Java application.

Client Jar has built with Apache CXF in Java 17.

The code to invoke Read Project from Project Service is

 URL wsdlURL = new URL(projectUrl);

      System.out.println("control here1 " +projectUrl);

      ProjectService service = new ProjectService(wsdlURL);

      System.out.println("control here2");

      ProjectPortType servicePort = service.getProjectPort();

      System.out.println("control here3");

      Client client = ClientProxy.getClient(servicePort);

      System.out.println("control here4");

      client.getOutInterceptors().add(new SAAJOutInterceptor());

      client.getInInterceptors().add(new SAAJInInterceptor());

      client.getOutInterceptors().add(new OutInterceptor(userName, password));

      System.out.println("control here5");

      List<String> fields = new ArrayList<String>();

      fields.add("Name");
