Can't no one do it. plz help me

Question

Hi Friends
I wrote a code in Applet for connecting Database.I did it using servlets and JSP successfully, and also the connection is created successfully when codding in main() for DOS Console, but now I try it in Applet but the ClassNotFoundException is occured in Applet. I m pasting exactly that code below, please tell me if there is any specific method of Applet for it, or any other solution. Thankyou
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import java.sql.*;
class Database extends Applet implements ActionListener
String str="";
public void paint(Graphics g)
g.drawString(str,10,10);
public void init()
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");//<< EXCEPTION OCCURED HERE
Connection con = DriverManager.getConnection("jdbc:odbc:DSNNAME","","");
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select * from data");
catch(Exception ex)
str = ex.getMessage();
repaint();
public void actionPerformed(ActionEvent event)

Search for examples of "signed applet" on the forum, tutorials and around the web. Along with demonstrations of how, why and when to sign an applet, you will also pick up bits of how to sign keys and what sort of database setups will work for what you are trying to achieve here.
You might think about how your assignment will actually be deployed in reality when it is graded in order to choose the best solution for your assignment. For instance, will the instructor mark this on a machine that you can pre-configure with a good odbc connection and provide a database to? Could you get at the instructors machine (with their permission of course) and set up a security properties file that grants your applet the necessary permissions to make the network connections you will need to achieve the results you want? To make a true applet though, ...available online to the public at large through a web server... you will need a signed applet.
Either your instructor wants you to build something impractical (hacking access on a single machine), wants you to pull off the challenging task of building and deploying a signed applet (do you really have that sort of access to the server and database), or wants you to discover why applets are not the medium for delivering this sort of application (if you've already done this in a jsp you are going to be real disappointed). Maybe this assignment is to alert you to the concept of the sandbox, which makes it a good exercise in security, but not necessarily a good example of picking the right tool for the right job. But hey, only you will know this after your assigment has been completed ...good luck!
