如果您在Linux上使用Firefox访问https://eagletw.mohavecounty.us/treasurer/treasurerweb/search.jsp，您将看到您可以很好地浏览该网站。
但是当我编译并运行下面的程序时：

import com.gargoylesoftware.htmlunit.html.*;
import com.gargoylesoftware.htmlunit.javascript.*;
import java.io.*;

public class BadWebsiteCertificate {
    public static void BadWebsiteCertificate () {
        try (final WebClient webClient = new WebClient()) {
            System.getProperties().put("org.apache.commons.logging.simplelog.defaultlog", "fatal");
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);

            webClient.getOptions().setCssEnabled(false);
            webClient.setJavaScriptErrorListener(new SilentJavaScriptErrorListener());
            webClient.setCssErrorHandler(new SilentCssErrorHandler());
            webClient.setAjaxController(new NicelyResynchronizingAjaxController());
            HtmlPage page = webClient.getPage("https://eagletw.mohavecounty.us/treasurer/treasurerweb/search.jsp");
            webClient.waitForBackgroundJavaScriptStartingBefore(10000);
            page = (HtmlPage) page.getEnclosingWindow().getEnclosedPage();
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            webClient.setJavaScriptErrorListener(new SilentJavaScriptErrorListener());
            HtmlTable grdTaxHistory = (HtmlTable) page.getElementById("grdTaxHistory");
            HtmlTableDataCell cpCell = (HtmlTableDataCell) grdTaxHistory.getCellAt(4,6);
            ((HtmlAnchor) cpCell.getFirstChild().getNextSibling()).click();

            webClient.waitForBackgroundJavaScriptStartingBefore(1_000);
            page = (HtmlPage) page.getEnclosingWindow().getEnclosedPage();
        }

        catch (Exception e) {
            System.out.println("Error: "+ e);
        }

    }

    public static void main(String[] args) {
        File file = new File("validParcelIDs.txt");
        BadWebsiteCertificate();
    }

}

使用以下命令：

javac -classpath ".:/opt/htmlunit_2.69.0/*" BadWebsiteCertificate.java
java -classpath ".:/opt/htmlunit_2.69.0/*" BadWebsiteCertificate

我收到以下运行时错误消息：

Error: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我尝试了Resolving javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed Error?提出的以下解决方案

echo -n | openssl s_client -connect eagletw.mohavecounty.us:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/eagletw.mohavecounty.us.crt
sudo keytool -import -v -trustcacerts -alias eagletw.mohavecounty.us -file ~/eagletw.mohavecounty.us.crt -keystore /usr/lib/jvm/java-11-openjdk-amd64/lib/security/cacerts -keypass changeit -storepass changeit

但这并没有解决问题。我仍然得到相同的运行时错误消息。
你知道我还能做什么吗？
