Calling a SharePoint Web Service using dynamic invocation procedure with NTLM authentication?

[Praveen Kumar Jayaram]

Hello,

I am trying to call a SharePoint web service from Java using dynamic invocation procedure. But am not sure how to plugin NTLM to this piece of code.
I have done this successfully by creating stub (Axis 2) but this requires many jar dependencies. Hence to reduce the dependency, am trying DII methodology.

Not finding a way because NTLM auth is set on stub usually and don't have any stub in DII.
Kindly suggest me a way to use NTLM authentication with this, (please find the code below)

String targetNamespace = "http://microsoft.com/webservices/OfficeServer/QueryService";

try { 
            /* Service lookup */
            ServiceFactory serviceFactory = ServiceFactory.newInstance();
            javax.xml.rpc.Service service = serviceFactory.createService(new QName(targetNamespace, "QueryService"));
            
            
            /* Service access */
            Call call = (Call) service.createCall();
            call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY, "");
            call.setProperty(Call.OPERATION_STYLE_PROPERTY, "wrapped");
            call.setProperty(Call.USERNAME_PROPERTY, "user");
            call.setProperty(Call.PASSWORD_PROPERTY, "welcome");
            call.setTargetEndpointAddress("http://ip_address/_vti_bin/search.asmx?wsdl");
	    call.removeAllParameters();
	    call.setPortTypeName(new QName(targetNamespace, "QueryServiceSoap"));
	    call.setOperationName(new QName(targetNamespace, "Status"));
            System.out.println(call.invoke(new Object[] {}));
}catch(Exception e) {
            e.printStackTrace();
        }

Above piece of code gives error: (401) Unauthorized

Meanwhile I tried another technique by using Apache Commons HttpClient (by calling getMethod)...But this gives me text/HTML response which would be rendered in browser.
Is there a way to call a specific method like Status() on web service??

I have pasted this code too,

HttpClient httpClient = new HttpClient();
	    Credentials credentials =  new NTCredentials("user",
	"welcome", "ip_address", "host_name");
	    httpClient.getState().setCredentials(AuthScope.ANY,credentials);
	    HttpMethodBase method = new
	GetMethod("http://ip_address/_vti_bin/search.asmx"); //tried appending "?op=Status" to call Status method..no help!
	        
	    try {
	      int returnCode = httpClient.executeMethod(method);
	      String response = method.getResponseBodyAsString();
	      System.out.println("Response: " + response);
	    } catch (HttpException e) {
	      e.printStackTrace();
	    } catch (IOException e) {
	      e.printStackTrace();
	    }
	}

Thanks a bunch in advance.
