I tried to create SOAP client to communicate with server. Everything runs smoothly with C# but on Java I still get some exceptions.

Our company is behind proxy. SOAP service is behind basic authentication.

Small behind story: I generated code with Java generate schema with JAX_WS from wsdl

/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.2.9-b130926.1035
 * Generated source version: 2.2
 */
@WebServiceClient(name = "ServiceWs", targetNamespace = "http://www.web.org/Schema/Klient/Service", wsdlLocation = "https://app.web.org/KlientWS/ServiceWs.wsdl")
public class ServiceWs
        extends Service {
    public ServiceWs(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
        super(wsdlLocation, serviceName, features);
    }
    ...
}

And with implementation authentication and cookies of some kind: 

CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
            System.setProperty("java.net.useSystemProxies", "true");

            System.setProperty("proxySet", "true");
            System.setProperty("proxyHost", localProxyHost);
            System.setProperty("proxyPort", localProxyPort);
            System.setProperty("proxyUser", localProxyUser);
            System.setProperty("proxyPassword", localProxyPassword);
            String prot = getRequestingProtocol().toLowerCase();

            // Requesting protocol
            System.setProperty(prot + ".proxyHost", localProxyHost);
            System.setProperty(prot + ".proxyPort", localProxyPort);
            System.setProperty(prot + ".proxyUser", localProxyUser);
            System.setProperty(prot + ".proxyPassword", localProxyPassword);

//          if (getRequestorType() == RequestorType.PROXY) {
//              if (getRequestingHost().toLowerCase().equals(localProxyHost.toLowerCase())) {
//                  if (Integer.parseInt(localProxyPort) == getRequestingPort()) {
//                      // Seems to be OK.
//                      return new PasswordAuthentication(localProxyUser, localProxyPassword.toCharArray());
//                  }
//              }
//          } else
            if (getRequestorType() == RequestorType.SERVER) {
                return new PasswordAuthentication(username, password.toCharArray());
            }
            return null;
        }
    });

And implementation of client

ServiceWs client;
try {
    URL url = new URL(endpointAddress);
    client = new ServiceWs(url);
} catch (IOException e) {
    client = new ServiceWs();
}

And it just fails there with ProtocolException with too many redirections while connecting to wsdl file.

I know authentication details are correct and web address is correct, as I can connect to the wsdl file manually.

    I suspect it is your proxy. Is it using NTLM? Try with proxy-vole and / or use javax.net.debug to debug network issues. – beat Oct 31 '17 at 10:14
  • We do have NTLM, does it change anything? :/ – Polostor Nov 01 '17 at 14:27

    @Polostor yes, it does - your NTLM proxy probably needs authentication, and if incorrect redirects you. Just google for your exception and ntlmv2, you will see many related issues. Either try to auto-setup your proxy via https://github.com/MarkusBernhardt/proxy-vole, or try to debug your issue with javax.net.debug. – beat Nov 02 '17 at 12:06

The problem was, as @beat suggested in the proxy settings. I have not set the NTLM properly, as our proxy user is in different domain.

The code to be set was System.setProperty("http.auth.ntlm.domain", domain); and after setting this everything started to work as intended.

More to be seen in J2SE Proxy Authentication.

private void createAuthentication(String localProxyHost, String localProxyPort, 
    String localProxyUser, String localProxyPassword, String domain, 
    String username, String password) {

    if (!prepared) {
        System.setProperty("java.net.useSystemProxies", "true");

        System.setProperty("http.auth.ntlm.domain", domain);
        System.setProperty("proxyHost", localProxyHost);
        System.setProperty("proxyPort", localProxyPort);
        System.setProperty("proxyUser", localProxyUser);
        System.setProperty("proxyPassword", localProxyPassword);

        prepared = true;
        CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
        Authenticator.setDefault(new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password.toCharArray());
            }
        });
    }
}

As requested by Polostor, I try to write an answer. NTLMv2 Proxies are authenticating the user, and if not sucessful redirect you.

As I had a lot of issues with different proxies at different sites, I do recommend using proxy-vole. This will do an automatic setup of your proxies based on the platform settings.
