Jdbc Connection using MySql DataBase

[rajeshlab]

I had written the program JDBCConnection. i.e.,

 import java.sql.*;

   public class Connect
   {
       public static void main (String[] args)
       {
           Connection conn = null;

           try
           {
	       String userName = "Root";
               String password = "admin";
               String url = "jdbc:mysql://localhost:3306/test";
               Class.forName ("com.mysql.jdbc.Driver").newInstance ();
               conn = DriverManager.getConnection (url,userName ,password );
               System.out.println ("Database connection established");
           }
           catch (Exception e)
           {
               System.err.println ("Cannot connect to database server");
           }
       }
   }

Here admin is mysql password.

I had copied the mysql-connector-java-5.0.8-bin.jar file in the location of C:\Program Files\Java\jdk1.5.0\jre\lib folder and set the class path as same path.

When i had compile the program it has compile successfully. But when i was runeed it has displayed an error message.
i.e.,

Exception in thread "main" java.lang.NoClassDefFoundError: Connect

Please tell me what is the mistake any one knows.
