In the first example from http://htmlunit.sourceforge.net/gettingStarted.html
    
    The following line of code
    
    final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");
    
    Results in a the following exception.
    
    java.lang.IllegalArgumentException: Cannot locate declared field class org.apache.http.impl.client.HttpClientBuilder.sslContext

    This problem also occurs in the 2.19 build, but that is not an option in the drop down.

    Looks like you have a wrong version of HttpClient in your classpath.

    This occurs is both and 2.18 & 2.19. If the tutorial only works with an earlier version then that should be made explicit or the tutorial changed to what ever the new form is. AIH that tutorial explict quoites the following, which is what I used to resolve the dependencies for the build.
    
    <dependency>
    <groupId>net.sourceforge.htmlunit</groupId>
    <artifactId>htmlunit</artifactId>
    <version>2.19</version>
    </dependency>

    Martin,
    not sure if i got your point...
    The dependency you mention is correct and if you have a look at the pom behind this dependency (e.g. http://mvnrepository.com/artifact/net.sourceforge.htmlunit/htmlunit/2.19) this pom points to the correct version (4.5.1) of HttpClient.
    Maybe there is a different component in your project that introduces an older HttpClient.
    
    Can you please verify that your classpath contains only the right HttpClient (have a look at Ahmeds comment below if you like to know how to check that).

    Hey RBRi. I am trying to test for a 404 error on an internal page, and I am also getting the same exception as the OP. It happens when I run the following line (my code has a different URL obviously, but it happens for any page with a 404 status, so this one works as well):
    
    final HtmlPage page = new WebClient().getPage("http://www.facebook.com/fjdkslfjdksl")
    
    Here is my stacktrace, beginning with the call from my code at the line above:

    Please print:
    
    System.out.println(HttpClientBuilder.class.getProtectionDomain().getCodeSource().getLocation());
    
    Which will provide your HttpComponent location, it should be version 4.5.1, not earlier

    That was the issue! I updated the dependency and now it works. Thanks!
