Java connection to a https URL

Question

I have written a small code in Java to access an URL . The code works fine for HTTP connection, but fails for HTTPS (the error is pasted below)

Any help to fix this will be greatly appreciated .

CODE :

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;


public class ConnectToWCProd {

    public static void main(String[] args) throws Exception {

        String userPassword = "user1:user1";
        String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());

        //URL oracle = new URL("http://<URL>/");
        URL oracle = new URL("https://<URL>");
        URLConnection yc = oracle.openConnection();

        yc.setRequestProperty("Authorization", "Basic " + encoding);

        BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) 
            System.out.println(inputLine);
        in.close();
    }

}

ERROR :

You have to include the certificate in jre/lib/security/cacerts (the default path)
