This is my Code of simple java

package com.crunchify;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.nio.charset.Charset;

/**
 * @author Crunchify.com
 * 
 */

public class CrunchifyCallUrlAndGetResponse {

    public static void main(String[] args) {
        System.out.println("\nOutput: \n" + callURL("http://cdn3.crunchify.com/wp-content/uploads/code/json.sample.txt"));
    }

    public static String callURL(String myURL) {
        System.out.println("Requeted URL:" + myURL);
        StringBuilder sb = new StringBuilder();
        URLConnection urlConn = null;
        InputStreamReader in = null;
        try {
            URL url = new URL(myURL);
            urlConn = url.openConnection();
            if (urlConn != null)
                urlConn.setReadTimeout(60 * 1000);
            if (urlConn != null && urlConn.getInputStream() != null) {
                in = new InputStreamReader(urlConn.getInputStream(),
                        Charset.defaultCharset());
                BufferedReader bufferedReader = new BufferedReader(in);
                if (bufferedReader != null) {
                    int cp;
                    while ((cp = bufferedReader.read()) != -1) {
                        sb.append((char) cp);
                    }
                    bufferedReader.close();
                }
            }
        in.close();
        } catch (Exception e) {
            throw new RuntimeException("Exception while calling URL:"+ myURL, e);
        } 

        return sb.toString();
    }
}

    You are trying to connect "http://cdn3.crunchify.com/wp-content/uploads/code/json.sample.txt", why does "https://www.urbanpro.com" appear in the error stack. – Yiping Huang Jul 01 '15 at 07:10
  • I doubt that the code-example produced the stacktrace. Running your sample code returns the content properly – Roman Vottner Jul 01 '15 at 07:47
  • actually i want content from https://urbanpro.com url so that i can use this please provide @YipingHuang – Abhinay Pandey Jul 01 '15 at 08:01
  • Your client doesn't trust the server's SSL certificate. – user207421 Jul 01 '15 at 08:20
  • As @EJP already mentioned, the certificate used by urbanpro is not trusted by your JVM. You can trust the cert by adding it to your JVMs truststore. HTTPS URIs should automatically create a [HttpsURLConnection](http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/HttpsURLConnection.html) instance to my knowledge. You could try to debug it using this [sample-code](http://www.mkyong.com/java/java-https-client-httpsurlconnection-example/) or setting the logging for the SSL/TLS to debug as explained [here](http://docs.oracle.com/javase/7/docs/technotes/guides/security/jsse/ReadDebug.html) – Roman Vottner Jul 01 '15 at 08:28
  • thanks to All i have solve my problem itself by using boilerpipe parser using http://boilerpipe-web.appspot.com/extract?url= thankyou – Abhinay Pandey Jul 01 '15 at 11:28
