Java Database Connectivity (JDBC)

Hello,
I am trying to get java to work with SQlite using the following code:

import java.sql.*;

public class Main {

public static void main(String[] args) throws Exception {
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
Statement stat = conn.createStatement();
ResultSet rs = stat.executeQuery("SELECT Question, Answer, Type FROM Questions");
while (rs.next()) {
System.out.println(rs.getString("1"));
System.out.println(rs.getString("2"));
System.out.println(rs.getString("3"));
}
rs.close();
conn.close();
}
}

But when I try to compile I keep getting the exception:

Exception in thread "main" java.lang.ClassNotFoundException: org.sqlite.JDBC

I have looked around other forums and I think I have downloaded the correct drivers for the SQLiteJDBC:
sqlitejdbc-v043-native.jar and sqlitejdbc.dll from http://www.zentus.com/sqlitejdbc/.

I have read that these files need to be put on the classpath and the java library paths respectively however I am unsure how to do this. Also if I do manage to get these files onto their paths would the same have to be done on every computer that I want to run this program on?

Many thanks

Mark
