Thread: connection issue in java desktop database application using derby database

Hello Java forum members !

Firstly please forgive my ignorance , I am beginner in java database programming.
I cannot make connection to Embedded derby database. This is what I did

1)created derby database with one table using netbeans 7.1.2. And inserted some data in that table via sql command

Now I want to read data from this database's table from a java class but I am getting this message when I run

Errorjava.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver

here is my code of the class

 
 
package mypackage;
 
import java.sql.*;
 
 
 
public class DbConnection {
 
    Connection con;
    Statement st;
    ResultSet rs;
 
    public DbConnection() {
        connect();
 
    }
    public void connect() {
        try{
 
            String driver = "jdbc:derby:fida;user=scott;password=tiger";
            Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
 
 
            con= DriverManager.getConnection(driver);
            st=con.createStatement();
            String sql = "select * from APP.STUDENT";
            rs = st.executeQuery(sql);
            while(rs.next())
            {
                System.out.println(rs.getInt("ID"));
                System.out.println(rs.getString("name"));
                System.out.println(rs.getString("fname"));
 
            }
 
        }catch(Exception ex){
            System.out.println("Error"+ex);
        }
 
 
    }
    public static void main (String args[]){
        new DbConnection();
    }
 
}

Please help me out , and forgive my ignorance.
