Hello I am new to HtmlUnit, I've install the latest htmlunit-2.12.jar and I want to run a couple of examples to start understanding it. When I run this code I get many WARN messages. Why do i get WARN messages? Is there a way to turn them off? Do i need to know about the WARN messages?

package com.att.temp;

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.List;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.util.NameValuePair;

public class HtmlDelete {

	public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException {

		WebClient webClient = new WebClient();
		HtmlPage currentPage = 
			webClient.getPage("http://www.google.com/search?q=htmlunit");

		List<NameValuePair> headers = 
			currentPage.getWebResponse().getResponseHeaders();
		for (NameValuePair header : headers) {
			System.out.println(header.getName() + " = " + header.getValue());
		}
	}
	
	
 }

I can't remember what kind of logging it uses, but you should probably turn up the logging to error level
