Can't find class when connecting to db

Question

I have a db in MySQL-Front which I'd like to connect to a java-program.
I'm new to this and don't know what to write but after reading in this forum I've come up with these lines. I suppose that it is the code by the arrows that are my problem. What shall I write there? I've tried a lot and nothing works....
When I run the applet I get the "Class not found" so I guess it is "org.gjt.mm.mysql.Driver" that is my problem. What?
The db is on the same pc as the java-code. At the "DriverManager.getConnection()" i guess I shall write password, login.... But I have no such. I only start my db. What shall I write there?
Help me please!
import java.sql.*;
public class Car {
private String CarNumber;
private String Color;
private String Type;
private static Connection dbconn=null;
public Car (String car, String color, String type) {
CarNumber = car;
Color = color;
Type = type;
public Car() {}
public String getCarNumber() {return CarNumber;}
public String getType() {return Type;}
public String getColor() {return Color;}
public static boolean connect() throws SQLException {
- - - - - -> try {Class.forName("org.gjt.mm.mysql.Driver");}
catch (ClassNotFoundException e) {
System.err.println("Class not found");
(Runtime.getRuntime()).exit(1);
- - - - - -> dbconn = DriverManager.getConnection("????????????");
return dbconn !=null;
public static Car findCar (String seekCarNumber) throws SQLException {
PreparedStatement select = dbconn.prepareStatement("SELECT CarNumber, Color, Type" +
"FROM Car WHERE CarNumber =?");
select.setString(1,seekCarNumber);
ResultSet rs= select.executeQuery();
rs.next();
String n=rs.getString("CarNumber");
String c=rs.getString("Color");
String t=rs.getString("Type");
return new Car(n,c,t);

Your database should provide a JDBC driver JAR or something similar. Your Applet will need to make sure this is on its classpath (assuming it's called mysql.jar):
<applet code="..." archive="mysql.jar">
</applet>You should search the JDBC forum - Applets connecting to databases seem to be very popular (don't ask me why).
