HTMLUNIT 2.9 jar posting comments

Question

I wrote this code:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import com.gargoylesoftware.htmlunit.html.HtmlTextArea;
import java.util.ArrayList;
import java.util.List;

/**
*
* @author user
*/
public class YouTubeComment {

public static void main(String[] args) {
    boolean f = YouTubeLogin.login();
    try {
        if (f) {
            WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3_6);
            webClient.setRedirectEnabled(true);
            webClient.setJavaScriptEnabled(false);
            HtmlPage firstPage = webClient.getPage("http://www.youtube.com/watch?v=kqDacBDoVM4&feature=related");
            List<HtmlForm> forms = new ArrayList();
            forms = (List<HtmlForm>) firstPage.getForms();
            HtmlForm form = firstPage.getForms().get(1);

            HtmlTextArea commentArea = (HtmlTextArea)form.getTextAreaByName("comment");
            commentArea.setText("good");
         HtmlSubmitInput submitButton =(HtmlSubmitInput)form.getInputByName("");
            HtmlPage pageAfterPost = (HtmlPage) submitButton.click();
        } else {
            System.out.println("Sorry..! Login is not successful");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

This application can login to a YouTube account with the username and password.
I want to write some code for posting comments after the successful login.
Please Help.

Could you at least post the URL where you want to post a comment? — Guillaume Polet, Apr 14 '12 at 08:42

Forgive me for asking, but is there some valid reason you want to do this? I'm afraid to offer help if this is just a giant spam engine. — john_science, Apr 15 '12 at 01:50

Ok, so you should probably try to look at the HTML content of the page with Firebug on Firefox to see what are the fields to use to post a comment.

From what I've seen, you need to find a div called 'comments-view'. A bit deepers in that div, there is a form with an action /comment_servlet?add_comment=1. Then you should fill in the textarea comment (it has its name attribute set to 'comment'). Eventually, you need to find the "Publish" button and click on it.

by writing this code: HtmlForm form = firstPage.getFormByName("/comment_servlet?add_comment=1"); its throwing an exception, com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[form] attributeName=[name] attributeValue=[/comment_servlet?add_comment=1] at com.gargoylesoftware.htmlunit.html.HtmlPage.getFormByName(HtmlPage.java:562) at htmlunitexample.YouTubeComment.main(YouTubeComment.java:32) – user1319054 Apr 14 '12 at 10:01
the form does not have a name, it only as an action and class which is not sufficient to find it. What you can do is find the div with id 'comments-view' and inside find the form, using `getHtmlElementsByTagName` (there should be only one) – Guillaume Polet Apr 14 '12 at 10:50
