X509TrustManager htmlunit implementation available

Question

For some reason, my code with everything imported correctly using Htmlunit throws an error.

package htmlunittesting; import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.HtmlAnchor; import com.gargoylesoftware.htmlunit.html.HtmlDivision; import com.gargoylesoftware.htmlunit.html.HtmlPage; public class httpunittest { public static void main(String[] args) throws Exception{ final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("https://blockchain.info/address/17iyEdbcG3G6RrDHYsi2MzG6RY8vRYvjXm"); final HtmlDivision div = page.getHtmlElementById("final_balance"); // final HtmlAnchor anchor = page.getAnchorByName("anchor_name"); System.out.println(div); webClient.closeAllWindows(); } } 

My mistake:

  Caused by: java.security.cert.CertificateException: No X509TrustManager implementation available at sun.security.ssl.DummyX509TrustManager.checkServerTrusted(Unknown Source) ... 27 more 

All I want to do is print the final balance on this test wallet.

And yes, this is all my code, no other classes.

You must add these parameters to the java virtual machine:

  System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol"); Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); System.setProperty("javax.net.ssl.trustStoreType", "JKS"); System.setProperty("javax.net.ssl.trustStore", "../path/yourtruststore.jks"); System.setProperty("javax.net.ssl.trustStorePassword", "yourpasswordfortruststore"); 

If you need mutual authentication:

  System.setProperty("javax.net.ssl.keyStore","../path../yourkeystore.jks"); System.setProperty("javax.net.ssl.keyStorePassword","yourpasswordforkeystore"); System.setProperty("javax.net.ssl.keyStoreType", "JKS");
