How can I contact an ssl secured webservice without a cert in a java app?

I have a very basic java webservice call...
public static String contactWebservice(){
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpHost target = new HttpHost(“www.someurl.com”, 443, "https");
HttpGet getRequest = new HttpGet("PARAMETERS FOR WEBSERVICE");
HttpResponse httpResponse = httpclient.execute(target, getRequest);
…more code...
I need to turn this into a SSL call without a cert. Much like a browser contacts an ssl secured webpage and gets data back without having a cert. I've tried many different methods but nothing has worked so far. I keep getting "peer not authenticated" errors.

SharePoint 2010 REST Java authentication

I was happy to access SharePoint using PowerShell. It just picked -DefaultCredential and I didn't have to worry about that. That was for prototyping.
But my actual code is Java. Now I am not sure about this at all.
Even though I make REST calls, even SOAP would fail if I don't authenticate properly.
Method 1 : NTLM
Here the only thing I am not sure about is the workstation ID. I login using Citrix to a VM and there is an explicit Workstation ID. I use that.
Returns 401.
DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://teams.host.com/_vti_bin/listdata.svc/");
NTCredentials credentials = new NTCredentials("user", 'pass', "workstation", "Domain");
client.getCredentialsProvider().setCredentials(new AuthScope("teams.host.com",80), credentials);
HttpResponse response = client.execute(request);
Method 2 : Basic authentication.
HttpGet request = new HttpGet("http://teams.host.com/_vti_bin/listdata.svc/");
CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY,
new UsernamePasswordCredentials("user", "password"));
CloseableHttpClient httpClient =
HttpClientBuilder.create().setDefaultCredentialsProvider(credentialsProvider).build();
HttpResponse response = httpClient.execute(request);
Returns 401.
What other method do I use ? Digest ? Since I don't know how -DefaultCredential in PowerShell worked I am back to the drawing board.
How should I investigate this ? I must be making some basic mistakes in this Java code. The flow is not right. That is my supposition.

So from Apache HttpClient this is the code that connects to SharePoint 2010. The workstation ID is the one used when I use Citrix XenDesktop to login to a Windows machine. I am able to get the result of my REST Get request.
This uses NTLM authentication.
DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://teams.host.com/_vti_bin/listdata.svc/");
NTCredentials credentials = new NTCredentials("user", 'pass', "workstation", "Domain");
client.getCredentialsProvider().setCredentials(new AuthScope("teams.host.com",80), credentials);
HttpResponse response = client.execute(request);

Java HttpClient get redirect status of first redirect

I am trying to use HttpClient to make HTTP requests in Java. Whenever a url redirects me, I would like to know the status code of the original request and the final url. If I do not disable redirects, the status code is just the status code of the last successful request:
// google.com = tinyurl.com
HttpUriRequest httpUriRequest = new HttpGet("https://google.com/cqvga");
HttpClient httpClient =
HttpClientBuilder.create()
.build();
HttpResponse response = httpClient.execute(httpUriRequest);
System.out.println(response.getStatusLine().getStatusCode()); // 200
System.out.println(response.getHeaders(HttpHeaders.LOCATION).length); // 0
However, if I disable redirect handling then I get the redirect status:
HttpClient httpClient =
HttpClientBuilder.create()
.disableRedirectHandling()
.build();
System.out.println(response.getStatusLine().getStatusCode()); // 301
System.out.println(response.getHeaders(HttpHeaders.LOCATION).length); // 1
Is there anyway without me writing my own RedirectHandler to know the original status code of my first request, and the final url I landed on?

What do I need to set up for the execute() of org.apache.http.client.HttpClient to work?

I am new to android and I'm making a simple app that sends a JSON object to the server. The many examples that I found on the internet had the following three lines of code:
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(prepai.host22.com/LoadStory.php);
HttpResponse httpResponse = httpClient.execute(httpPost);
I tried to run them but the app running in the eclipse emulator crashed when the execute() function got executed. I got this log:
Caused by: java.lang.IllegalStateException: Target host must not be null, or set in parameters. scheme=null, host=null, path=prepai.host22.com/LoadStory.php
How do I give the host a value? Also do I have to do all the communication in a separate thread? Or is there anything else that I need to do?

You should pass the full url (including the http or https) as a string, for example:
HttpPost httpPost = new HttpPost("http://prepai.host22.com/LoadStory.php");

HTTPs over a proxy with apache http client

I have a http client which is based on the apache http client and it seems to have no problem with ssl certificates. I have a unit test for both globally recognized certs and self signed certs with a custom SSLSocketFactory.
However when I ran the same code behind a proxy, it stopped working. I keep getting this dreaded exception:
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:352)
at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:128)
at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:572)
at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:180)
at org.apache.http.impl.conn.ManagedClientConnectionImpl.open(ManagedClientConnectionImpl.java:294)
at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:640)
at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:479)
at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906)
at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:805)
I reduced the code to the bare minimum and it still throws the same exception. The code:
URI uri = new URI("https://www.google.com");
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
new HttpHost("proxy.int", 8080, "https"));
HttpUriRequest request = new HttpGet(uri);
HttpResponse response = client.execute(request);
I wasn't sure if it uses the default ssl settings if nothing is specified so I added it explicitly as well:
URI uri = new URI("https://www.google.com");
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
new HttpHost("proxy.int", 8080, "https"));
client.getConnectionManager().getSchemeRegistry().register(
new Scheme("https", 443, SSLSocketFactory.getSystemSocketFactory()));
HttpUriRequest request = new HttpGet(uri);
HttpResponse response = client.execute(request);
I also tried the getSocketFactory() (not entirely sure what the difference is with getSystemSocketFactory()), still the same error though.
EDIT:
The proxy has optional authentication and I have tried both with and without. The authentication information was set using the following code:
client.getCredentialsProvider().setCredentials(
new AuthScope("proxy.int", 8080),
new UsernamePasswordCredentials("user", "password")
);
Exactly the same error.

The problem was in the proxy declaration, I had to specify "http" instead of "https":
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
new HttpHost("proxy.int", 8080, "http"));
