Server returned HTTP response code: 401 for URL: https

http-status-code-401, https, java, tomcat

Solution

401 means "Unauthorized", so there must be something with your credentials.

I think that java `URL` does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

Problem

I'm using Java to access a HTTPS site which returns the display in an XML format. I pass the login credentials in the URL itself. Here is the code snippet: ``` DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); requestURL = "https://Administrator:Password@localhost:8443/abcd"; try { InputStream is = null; URL url = new URL(requestURL); InputStream xmlInputStream =new URL(requestURL).openConnection().getInputStream(); byte[] testByteArr = new byte[xmlInputStream.available()]; xmlInputStream.read(testByteArr); System.out.println(new String(testByteArr)); Document doc = db.parse(xmlInputStream); System.out.println("DOC="+doc); } catch (MalformedURLException e) { } ``` I'm creating a trust manager in the program which does not validate signed/unsigned certificates. But, on running the above program, I get the error Server returned HTTP response code: 401 for URL: https://Administrator:Password@localhost:8443/abcd I can use the same url on my browser and it displays the xml correctly. Kindly let me know how to make this work within the Java program.
