Note: Our Host application which invokes this JAR file (actually the class) supports only JVM 1.5. Since the trigger for the code is from the application, we don't have any other go but to restrict our Java code to JDK 1.5 compatibility.

Below is the code I've tried:

        String webPage = "https://api.twilio.com/2010-04-01/Accounts";
        URL url = new URL(webPage);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic BASE64ECONDED_STRING_OF_LENGTH_93_CHARACTERS_WITHOUT_ANY_WHITESPACE");
        //((HttpURLConnection) urlConnection).setRequestMethod("GET");//I get same error with or without this
        InputStream is = urlConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);

        int numCharsRead;
        char[] charArray = new char[1024];
        StringBuffer sb = new StringBuffer();
        while ((numCharsRead = isr.read(charArray)) > 0) {
            sb.append(charArray, 0, numCharsRead);
        }
        String result = sb.toString();

        System.out.println("*** BEGIN ***");
        System.out.println(result);
        System.out.println("*** END ***");

The error I keep receiving is this:

Looks like Basic Authorization isn't supported in Java 1.5. The very same code works in Java 1.7. I got the success response too. Is there a way I can get it working in Java 1.5?

    Is there any strong reason it needs to work in Java 1.5? This version is end-of-life since a very long time, and I would rather invest in upgrading the application to use Java7 or even better Java8 Commented Nov 4, 2015 at 10:13
  • Yes. Our Host application which invokes this JAR file supports only JVM 1.5. It's indeed a lagging. But we don't have a choice. Commented Nov 4, 2015 at 10:15

    I don't think that error is because you're using Basic auth. It has something to do with the cryptography on your SSL connection.. Commented Nov 4, 2015 at 10:21
