WSDL Client Calling Failed

XuSen :

First time working on SOAP services. I need to call this web service. http://demomt.weblite.com.my/TS_Services/SubmissionsService.asmx?WSDL

Here are the 2 out of 11 of the stubs that i have generated using wsimport

I tried for the whole day, but I keep getting this error message. Why? I suspect because i did not pass in the authentication header correctly. But at the same time i'm wondering how come the generated stub does not comes with Authentication header as a method param? is that normal? Need help. I'm so confusing.

Exception in thread "main" com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: Server was unable to process request. ---> Object reference not set to an instance of an object. Please see the server log to find more detail regarding exact cause of the failure.

        MailAdapterApplication adapterApplication = new MailAdapterApplication();
        adapterApplication.run();
    }

    public void run() throws MalformedURLException {

    WebLITETSServices services = new WebLITETSServices();
    WebLITETSServicesSoap servicesSoap = services.getPort(WebLITETSServicesSoap.class);
    Map<String, Object> req_ctx =((BindingProvider)servicesSoap).getRequestContext();
    Map<String, List<String>> headers = new HashMap<>();
    headers.put("Username",Collections.singletonList("[email protected]"));
    headers.put("Password", Collections.singletonList("P@ssW0rd32!"));
    headers.put("APIKey", Collections.singletonList("QdrLKxog"));

    req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
    System.out.println(servicesSoap.getTemplateList());

    }

}

Client received SOAP Fault from server: Server was unable to process request.

I keep getting this error message. Why?

Indeed you did call the service, but the server returned an error code with error message, where the returned payload has no mapping to any expected return type or soap fault exception. There is no more information in the in the text you've provided.

It would be really usefull to check the response status code and payload which was really returned. How to log the respone payload depends on the webservice library you use (cxf, axis2, ??)

I suspect because i did not pass in the authentication header correctly.

You should confirm that suspission, from the information provided it is not possible to tell. Though if you did not provide any authentication information, it is very possible

But at the same time i'm wondering how come the generated stub does not comes with Authentication header as a method param? is that normal? Need help. I'm so confusing.

I assume under the "Authentication header" you mean AuthHeader header. You may need to enable header generation when invoking the wsimport, as well depends in th framework used. When using wsimport from the default JDK, try to use -XadditionalHeaders parameter
