How to Request an External JSON URL From Within Java Servlet or Class When the JSON URL sits behind NTLM Authentication On Another Server/Domain

Accessing the following JSON URL from within the web browser is simple on a Windows machine as this pops up an authentication box asking for the username and password which when entered displays the JSON data correctly.
www.json-behind-ntlm-authentication.com/view-data
I am now trying to move this into a Java Servlet.
I have tested the HttpClient library, http://hc.apache.org, and every example I have tried from their documentation, doesn't work. Most of the code I've tried doesn't even compile correctly.
I have also tested Jsoup, https://jsoup.org/, as that is a very good library for web scraping, but this doesn't seem to support accessing pages behind NTLM authentication.
I have also tested the code found here, https://blogs.msdn.microsoft.com/freddyk/2010/01/19/connecting-to-nav-web-services-from-java/, which is the only code sample I can find related to accessing a JSON URL that sits behind NTLM authentication. This is actually what I'm looking to achieve, a Java web application accessing Microsoft Nav data through their web services - and even this official example doesn't compile.
Any pointers / options? There must be a Java library somewhere that has this problem solved? The access is currently over HTTP, but ultimately is going to be over SSL for security reasons, so any solution must also support SSL handshakes.
I would really like not to build a separate C# application using LINQ, https://blogs.msdn.microsoft.com/freddyk/2009/04/20/using-linq-with-nav-web-services/, which I would hope works, but I'm not hopeful that the C# example would work in this scenario based on the Java examples not compiling.
UPDATE
After an awful lot of searching, I've found the following code below which seems to be close to working, but not quite - See the comments in the code where this is breaking. Thanks for the pointers in the comments already.
DefaultHttpClient httpclient = new DefaultHttpClient();
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.NTLM);
httpclient.getParams().setParameter(AuthPNames.TARGET_AUTH_PREF, authpref); //ERROR - This causes an error: java.lang.VerifyError: Cannot inherit from final class
NTCredentials creds = new NTCredentials(username, password, "", domain);
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);
HttpHost target = new HttpHost(baseURL);
// Make sure the same context is used to execute logically related requests
HttpContext localContext = new BasicHttpContext();
// Execute a cheap method first. This will trigger NTLM authentication
HttpGet httpget = new HttpGet(baseURL);
HttpResponse response1 = httpclient.execute(target, httpget, localContext); //ERROR - This line is throwing an error: java.lang.VerifyError: Cannot inherit from final class
HttpEntity entity = response1.getEntity();
System.out.println(EntityUtils.toString(entity));
I'm still unsure how to actually solve this problem. Any additional pointers?

org.apache.http.auth has NTCredentials which you can use in a HttpComponentsMessageSender in a spring boot #Configuration
HttpComponentsMessageSender httpComponentsMessageSender = new HttpComponentsMessageSender();
NTCredentials credentials = new NTCredentials("username", "password", null, "domain");

HttpTransportProperties.Authenticator is not found in Axis2

Just generated Java code from WSDL using Apache Axis 2. The service is protected with basic authentication. When I try to create authentication object in order to set the username and password, the class (HttpTransportProperties.Authenticator) is not found in the library.
How can I set basic authentication for the client code generated by Apache Axis2?
Here is the old way of setting basic authentication params:
HttpTransportProperties.Authenticator basicAuth = new HttpTransportProperties.Authenticator();
basicAuth.setUsername("username");
basicAuth.setPassword("password");
basicAuth.setPreemptiveAuthentication(true);
final Options clientOptions = stub._getServiceClient().getOptions();
clientOptions.setProperty(HTTPConstants.AUTHENTICATE, basicAuth);
stub._getServiceClient().setOptions(clientOptions);

I had the same Problem!
Solution: Use HttpTransportPropertiesImpl instead of HttpTransportProperties.

org.apache.axis2.client.OperationClient _operationClient = _serviceClient.createClient(_operations[1].getName());
_operationClient.getOptions()
.setAction("http://asdf/checkOutRequest");
HttpTransportPropertiesImpl.Authenticator basicAuth = new HttpTransportPropertiesImpl.Authenticator();
basicAuth.setUsername("tomcat");
basicAuth.setPassword("tomcat");
basicAuth.setPreemptiveAuthentication(true);
final Options clientOptions = _operationClient.getOptions();
clientOptions.setProperty(HTTPConstants.AUTHENTICATE, basicAuth);
_operationClient.setOptions(clientOptions);
For anybody needing a even more explicit example of uwesch's very helpful answer.

How do you send a binary file to a webservice using Axis2?

I was using Axis 1.4 on a project and I am moving to Axis2 1.6.3. I am asking this because in Axis1.4 it was quite straightforward :
myStub.addAttachment(new DataHandler(new FileDataSource("path_to_file")));
You just add a DataHandler to the Stub and then send it. But in Axis2 it seems that this method doesn't exist. So I was wondering what is the new way of attaching a DataHandler to a stub ?
As I was searching on the internet, I find out that you have to attach the DataHandler to the MessageContext (Downloading a Binary File from a Web Service using Axis2 and SOAP with Attachments).
So I did As it is said :
MessageContext messageContext = MessageContext.getCurrentMessageContext();
OperationContext operationContext = messageContext.getOperationContext();
MessageContext outMessageContext = operationContext.getMessageContext(WSDLConstants.MESSAGE_LABEL_OUT_VALUE);
outMessageContext.addAttachment(new DataHandler(new FileDataSource("path_to_file")));
But the problem is that MessageContext.getCurrentMessageContext() return null. I think that it is not working because this snippet should be used on the server side. What I want is to be able to send a file to the server not retrieve one from the server.
I might be missing something. Maybe this is not the way to do it, anyway any help is appreciated. In the meantime I'll keep up searching on the internet and if I find something I'll let you know :)

So after some time I figured out how to do it on Axis2 Documentation.
Go to SOAP with Attachments (SwA) with Axis2 and on the second section named Sending SwA Type Attachments. Here you will find out how to send a file to the server.
This is the code snippet they provide :
public void uploadFileUsingSwA(String fileName) throws Exception {
Options options = new Options();
options.setTo(targetEPR);
options.setProperty(Constants.Configuration.ENABLE_SWA, Constants.VALUE_TRUE);
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setSoapVersionURI(SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI);
options.setTo(targetEPR);
ServiceClient sender = new ServiceClient(null,null);
sender.setOptions(options);
OperationClient mepClient = sender.createClient(ServiceClient.ANON_OUT_IN_OP);
MessageContext mc = new MessageContext();
mc.setEnvelope(createEnvelope());
FileDataSource fileDataSource = new FileDataSource("test-resources/mtom/test.jpg");
DataHandler dataHandler = new DataHandler(fileDataSource);
mc.addAttachment("FirstAttachment",dataHandler);
mepClient.addMessageContext(mc);
mepClient.execute(true);
}

Apache Axis2 Java client to access Bronto SOAP WSDL

I've downloaded Apache Axis2, using the following link:
http://archive.apache.org/dist/ws/axis2/1_4_1/axis2-1.4.1-bin.zip
Then I used the following command to generate java classes:
wsdl2java.sh -uri https://api.bronto.com/v4?wsdl
total generated src:
BrontoSoapApiImplServiceStub.java
BrontoSoapApiImplServiceCallbackHandler.java
ApiExceptionException0.java
I was able to login using the following.
BrontoSoapApiImplServiceStub stub;
// Get the stub...
LoginE loginE = new LoginE();
Login login = new Login();
login.setApiToken("your token here");
loginE.setLogin(login);
// Call the web service; login
stub.login(loginE);
Now I try to addContacts, and needs SessionHeaderE, but I can't seem to link login to the sessionId, the following code is not right. I'm imaging after login, I should be able to get some session info. But I can't seem to find.
SessionHeader sessionHeader = new SessionHeader();
sessionHeader.setSessionId(param) // I don't know how to get sessionId from login info
SessionHeaderE sessionHeaderE = new SessionHeaderE();
sessionHeaderE.setSessionHeader(sessionHeader);
.....
AddContactsResponseE responseE = stub.addContacts(addContactsE, sessionHeaderE);
By the way, this is my first time working with Axis. Not sure what's the best way to approach the problem.
BrontoSoapApiImplServiceStub.java has more than 200,000 lines in it.

I got the answer from http://www.experts-exchange.com
String sessionId = stub.login(loginE).getLoginResponse().get_return();
Thanks.

Set custom SOAP header using Axis 1.4

I'm trying to consume a .NET 2.0 web service using Axis.
I generated the web services client using Eclipse WST Plugin and it seems ok so far.
Here the expected SOAP header:
<soap:Header>
<Authentication xmlns="http://mc1.com.br/">
<User>string</User>
<Password>string</Password>
</Authentication>
</soap:Header>
I didn't find any documentation on how to configure this header from an Axis client.
When I generated the client using Visual Studio C# Express 2008, it generates a class named Authentication with two String attributes (User and Password) and all the client methods receive an object of this class as first parameter, but it did not happen with Axis WS client.
How can I set this header in my client calls?

Maybe you can use org.apache.axis.client.Stub.setHeader method? Something like this:
MyServiceLocator wsLocator = new MyServiceLocator();
MyServiceSoap ws = wsLocator.getMyServiceSoap(new URL("http://localhost/MyService.asmx"));
//add SOAP header for authentication
SOAPHeaderElement authentication = new SOAPHeaderElement("http://mc1.com.br/","Authentication");
SOAPHeaderElement user = new SOAPHeaderElement("http://mc1.com.br/","User", "string");
SOAPHeaderElement password = new SOAPHeaderElement("http://mc1.com.br/","Password", "string");
authentication.addChild(user);
authentication.addChild(password);
((Stub)ws).setHeader(authentication);
//now you can use ws to invoke web services...

If you have an object representing the Authentication container with userid and password, you can do it like so:
import org.apache.axis.client.Stub;
//...
MyAuthObj authObj = new MyAuthObj("userid","password");
((Stub) yourServiceObject).setHeader("urn://your/name/space/here", "partName", authObj);

I have the same issue and solved by the below fragement:
ServiceSoapStub clientStub = (ServiceSoapStub)new ServiceLocator().getServiceSoap(url);
org.apache.axis.message.SOAPHeaderElement header = new org.apache.axis.message.SOAPHeaderElement("http://www.abc.com/SSsample/","AuthHeader");
SOAPElement node = header.addChildElement("Username");
node.addTextNode("aat");
SOAPElement node2 = header.addChildElement("Password");
node2.addTextNode("sd6890");
((ServiceSoapStub) clientStub).setHeader(header);

I used almost the same solution as mentioned before:
SOAPHeaderElement cigWsHeader = new SOAPHeaderElement("https://ws.creditinfo.com", "CigWsHeader");
cigWsHeader.addChildElement("UserName").setValue("username");
cigWsHeader.addChildElement("Password").setValue("password");
var port = new ServiceLocator().getServiceSoap(someUrl);
((Stub) port).setHeader(cigWsHeader);
And spent hours searching why "Security header not found". And the aswer is... redundant symbol "/" at the namespace: "https://ws.creditinfo.com/" . Seriously! Keep it in mind.
