Java: how to setup htmlunit

Question

I'm a pretty big noob to Java, but I would like try out htmlunit. I'm using netbeans as my IDE and I've created a project folder "hu1". Here is the structure for that folder:

hu1
 > nbproject
 > src 
   > hu1
 > test

Now, I download htmlunit 2.7 and unzipped the folder, which contains a "lib" folder with a bunch of jar files in it. Where do I put that lib folder in my netbeans project folder so that I can use htmlunit?

Also, once I have figured that out, what paths do I use for my imports. A lot of examples I've seen on the web use something like this:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.Page;

Where do the the com.gargoylesoftware come from?

I know this is a beginner questions, and I really should just read up on how to program with java more, but I would appreciate some advice from the experts here.

UPDATE: Here is a picture of my setup.

Now, I download htmlunit 2.7 and unzipped the folder, which contains a "lib" folder with a bunch of jar files in it. Where do I put that lib folder in my netbeans project folder so that I can use htmlunit?

First, register the libraries in the IDE.

1. In the IDE, choose Tools > Libraries to open the Libraries Manager.
2. Click New Library and provide a name for the library, e.g. "HTMLUnit"
3. With the "HTMLUnit" library selected, click on the "Add JAR/Folder..." button and select the jar file that was downloaded earlier and click OK to complete

_{(source: netbeans.org)}

Then, add the libraries to the project you are working on.

1. Select the project from the Project view, right-click and select "Properties"
2. Under the Libraries category, click on the "Add Library..." button and choose the HTMLUnit library and click OK to complete

_{(source: netbeans.org)}

(...) Where do the the com.gargoylesoftware come from?

From the library you have to add (more precisely, from the htmlunit jars).

Answer 2

com.gargoylesoftware.htmlunit

Is a package in one of the jar files you've downloaded. You have to make sure that these jar files are on the "classpath" in order for Java to find the classes inside (Page, BrowserVersion++). If you're using Netbeans dumping the jar's in the lib folder will usually do the trick.
