How to implement Scrypt in Java?

Question

I have really been struggling trying to get Bouncy Castle Scrypt going in my web app for password encryption. I am fairly new to programming in Java and security.

I have tried looking at Bouncy Castle's documentation for their Scrypt class. However, I have a really hard time trying to figure out how it works. It doesn't seem to really give much information as to how to create the class or anything like that.

I searched around Stack Exchange and Google to see if there is anywhere that could give me a good example as to what I should do to create this class. I found this question and answer, and I tried it out without creating a class, but that didn't seem to work either.

To top this off, my import doesn't seem to want to work either.

This is all of the code that I have:

import org.bouncycastle.crypto.generators;

public class SCrypt extends java.lang.Object {

    public Scrypt(){}

    public static byte[] generate(byte[] P,byte[] S,int N,int r,int p,int dkLen) {

    }
}

I want to use Scrypt since it seems to be the most secure in encrypting passwords, but it seems next impossible to implement. I'm really close with just going with a PBKDF2 since there is more documentation on it, but I'm hoping that there is someone out there who can help me get this going.

Thanks Hugo for the feedback! After much struggle and searching, I found this website: http://www.itcsolutions.eu/2011/08/22/how-to-use-bouncy-castle-cryptographic-api-in-netbeans-or-eclipse-for-java-jse-projects/

This helped give me a breakdown step-by-step on what I needed to get Bouncy Castle up and running on my computer. I hope this will help others since I struggled with it for so long to find something that broke this down into layman's terms. :)
