X509TrustManager实现不可用htmlunit

Question

For some reason my code with everything imported correctly, using Htmlunit causes 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 error is:

 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 out what the final balance is on this test wallet.

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

You should add these parameters to 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");
