Class not found java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

I wanted to print the contents in a database but whenever I run this program I got this error saying that

Class not found java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
SQL exception occuredjava.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/mydatabase

I have installed MySQL from this link http://dev.mysql.com/downloads/windows/installer/ its a 248mb file and installed completely. I can access my database within MySQL but can't able to access from netbeans. I separately downloaded the mysql-connector-java-5.1.4.jar and set the CLASSPATH but now also I got this error.

import java.sql.*;

public class jdbcResultSet {
   public static void main(String[] args) {
      try {
         Class.forName("com.mysql.jdbc.Driver");
      }
      catch(ClassNotFoundException e) {
         System.out.println("Class not found "+ e);
      }
      try {  
         Connection con = DriverManager.getConnection
         ("jdbc:mysql://localhost:3306/mydatabase","root",
         "root");
         Statement stmt = con.createStatement();
         ResultSet rs = stmt.executeQuery
         ("SELECT * FROM employee");
         System.out.println("id  name    job");
         while (rs.next()) {
            int id = rs.getInt("id");
            String name = rs.getString("name");
            String job = rs.getString("job");
            System.out.println(id+"   "+name+"    "+job);
         }
      }
      catch(SQLException e){
         System.out.println("SQL exception occured" + e);
      }
   }
}
