CXF Client Webservice Ping has thrown exception Could not send Message. Invalid address. Endpoint address cannot be null.

Question

I am getting the following error [1] from the following code:

ClassLoader cl = Thread.currentThread().getContextClassLoader();
        URL WSDL_LOCATION=null;
        if ( null == cl ) cl = SQLService.class.getClassLoader();
         WSDL_LOCATION = cl.getResource( "SQLServiceSoap.wsdl" );

        QName SERVICE_NAME = new QName("http://localhost:8080/gateway/services/SQLServiceSoap?wsdl", "SQLService");
        Service service = Service.create(WSDL_LOCATION,SERVICE_NAME);
        SOAPport sqlService = service.getPort(SOAPport.class);
  Client client = org.apache.cxf.frontend.ClientProxy.getClient(sqlService);
  Endpoint cxfEndpoint = client.getEndpoint();
        Map<String, Object> outProps = new HashMap<String, Object>();
  outProps.put(WSHandlerConstants.ACTION,
    WSHandlerConstants.USERNAME_TOKEN);
  outProps.put(WSHandlerConstants.USER, soapUser);
  outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
  outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS,
    PasswordCallbackHandler.class.getName());
  outProps.put("password", soapPass);
  WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
  cxfEndpoint.getOutInterceptors().add(wssOut);

  String result = sqlService.ping("test");
  LOG.warn("PONG!: " + result);

My unfamiliarity with webservices continues to cause me grief.

Answer 1

End point was not setup at all, and CXF does not configure your End Point for you if it is different than what you have in your WSDL.
