    Default Create a method to get integers from a https web page and store them in a array

    I'm new to Java and I'm trying to make a program that can read the integers (listed below) from this link and store them in an array. I've searched around and I can't find any info or working examples of how to do it.

    The integers are:

    17,04,2011,1,2,7,10,13,23,24,25,26,27,38,39,41,43, 45,48,49,55,59,62

    All integers will change each time the method is called. (Different links, same page layout)


    Could anyone help me with the code or point me in the right direction? Maybe someone knows about some good tutorials that explains this?

    Any help is greatly appreciated.


    Regards

    -B

    This is the first line of error code I get when trying to run any of the examples I've found:
    Exception in thread "main" javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
    The code I use in this example is:
    import java.net.MalformedURLException;
    import java.net.URISyntaxException;
    import java.net.URL;
    import java.net.URLConnection;
    import javax.net.ssl.HttpsURLConnection;
    import java.net.URI;
    import java.io.*;
     
    public class Main{
    	public static void main(String args[]) throws Exception {
     
    		//URI uri = new URI("https", "norsk-tipping.no", "/gar/wco", "event=getResultInfo&game_id=13&DrawID=1260&target=1&bet=10&keno_level=10");
    		//URL url = uri.toURL();
    		URL url = new URL("https://www.norsk-tipping.no/gar/wco?event=getResultInfo&game_id=13&DrawID=1260&target=1&bet=10&keno_level=10");
     
    		URLConnection conn = url.openConnection();
     
    		// Retrieve information from HTTPS: GET
    		InputStream istream = conn.getInputStream();
    		int ch;
    		while ((ch = istream.read()) != -1) {
    		    System.out.println("Test" + ch);
    		}
    		istream.close();
    	}
    }
    Does anyone know whats wrong?

    Hello Bøtteknotten.

    Welcome to the Java Programming Forums.

    This error is because you are attempting to connect to a secure HTTPS URL.

    Take a look at these links:

    unable to find valid certification path to requested target : GC - Garbage Collection? GotCha?
