HtmlUnit on webserver: method <init>()V not found

I've managed to run the code in this question here properly in a test java project with no problem, but when I am following the exact same procedure to import HtmlUnit in my webserver, i keep getting the org.apache.http.protocol.BasicHttpContext: method <init>()V not found error.

the code im trying to run:

    package com.testing;

import java.io.IOException;
import java.net.MalformedURLException;

import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;

public class testingUnit {

    public static void main(final String[] args) {
        final WebClient webClient = new WebClient();
        webClient.setTimeout(1000);
        try {
            System.out.println("Querying");
            webClient.getPage("https://bulksms.vsms.net/register/");
            System.out.println("Success");
        } catch (final FailingHttpStatusCodeException e) {
            System.out.println("One");
            e.printStackTrace();
        } catch (final MalformedURLException e) {
            System.out.println("Two");
            e.printStackTrace();
        } catch (final IOException e) {
            System.out.println("Three");
            e.printStackTrace();
        } catch (final Exception e) {
            System.out.println("Four");
            e.printStackTrace();
        }
        System.out.println("Finished");
    }

}

Console:

Solution

  • Figured it out after posting the screenshot here. I had totally forgot to update the web app libraries. I did that and deleted all the outdated versions of jars I had (in the webcontent/lib folder), and the code above worked like a charm. Cheers!
