Module 11 : Error running HtmlUnitDriver | Selenium Forum

 Posted on 01/08/2016
Hi,

I was trying to run this simple code:

HtmlUnitDriver hd = new HtmlUnitDriver();
hd.get("http://www.google.com");
System.out.println(hd.getTitle());

Imported the package: import org.openqa.selenium.htmlunit.HtmlUnitDriver;

Below is the error message that I get when running the code:

Exception in thread "main" org.openqa.selenium.WebDriverException: java.lang.IllegalArgumentException: Cannot locate declared field class org.apache.http.impl.client.HttpClientBuilder.dnsResolver

I have tried adding the following jars:

htmlunit-driver-standalone-2.21.jar and
httpclient-win-4.5.2.jar

But still getting the same issue. Please help

I checked the url that you have mentioned. (http://sqa.stackexchange.com/questions/20137/htmlunit-driver-error)

It was mentioned there as:

To see which jar is being used:
System.out.println(HttpClientBuilder.class.getProtectionDomain().getCodeSource().getLocation());

It should be "httpclient-4.5.2.jar"

I checked using the above code and found that the HttpClient version that I was using was httpclient-4.5.1.jar.
I download httpclient-4.5.2.jar and change the config to httpclient-4.5.2.jar.

But now I'm not getting any error, but instead of getting the page title.. I get the output as "Proxy Warning".

What else steps do I need to do?
