import java.sql.SQLException;
import java.sql.Statement;
public class JDBCTutorial{
    public static void main(String[] args){
        Connection con;
        Statement stmt;
        ResultSet srs;
        try{
            Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
            con = DriverManager.getConnection("jdbc.derby.COFFEES");
            stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
            srs = stmt.executeQuery("SELECT COF_NAME, PRICE FROM COFFEES");
            while(srs.next()){
                String name = srs.getString("COF_NAME");
                float price = srs.getFloat("PRICE");
                System.out.println(name + " " + price);
        }catch(ClassNotFoundException ex){
            ex.printStackTrace();
        }catch(SQLException ex){

Answer 1

Do you know what a classpath is?nope
Well this (classpath) is the crux of your problem.
How are you running this program? In netbeans.
well i registered java db by going to tools ->
options -> advanced options -> ide configuration ->
server and external tool settings -> java db database
and then choosing the java db location and database
location... this seems to be something netbeansy.
But this did not answer my question really.
All I can tell you is that you need to have all the directories and/or jarfiles your program needs to run in your runtime classpath. Runtime as opposed to compile time. I suspect that this "registration" process of which you speak is related to your compile-time classpath but either not your runtime classpath or you are not running in Netbeans.
