Somebody correct my code Iam trying to create an applet which connects DB

Question

This is throwing many mistakes iam trying to create an applet like an airplace booking which shows combo box of the available aircrafts and when selected it should show the no of available seats
import javax.swing.*;
import java.awt.*;
//<applet code=Aircraft_Booking width=500 height=500></applet>
public class Aircraft_Booking extends JApplet
JLabel           lblStdId;
JLabel          lblStdSeats;
JLabel          lblStdAircraft;
JComboBox      jcmbStdAircraft;
JTextField      jcmbStdSeats;
JTextField      jcmbStdId;
JPanel           panel;
//Member Function/
public void init()
panel = new JPanel();
lblStdId          =      new JLabel("Aircraft Booking");
lblStdSeats =      new JLabel("No of Available Seats");
lblStdAircraft =     new JLabel("Choose your Aircraft");
//txtStdId     =     new JTextField(5);/
String p = "Select * from Aircraft where aircrafttypeid";
/*Initialize and load the JDBC-ODBC Bridge driver*/
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
/*Establish a connection with a data source*/
Connection con = DriverManager.getConnection("jdbc:odbc:MyDataSource", "sa", "");
/*Create a Statement object to process the SELECT statement*/
Statement stmt = con.createStatement();
/*Execute the SELECT SQL statement*/
ResultSet rs = stmt.executeQuery(str);
jcmbStdAircraft = new JComboBox(p);
//Add all components to panel/
panel.add(lblStdId);
//panel.add(txtStdId);/
panel.add(lblStdAircraft);
panel.add(jcmbStdAircraft);
//Add Panel to JApplet/
getContentPane().add(panel);
}

Answer 1

When running an Applet connections can only be established back to the originating machine unless you have changed the security configuration of the client machine.
This means that you would only be able to connect to the database on the server from which the applet was loaded.
Contrariwise the JDBC-ODBC driver will try to connect to the database on the local machine. So I can't see that working unless this was your intention and you have made the appropriate security config changes - but in such a circumstance Applets are a rather odd choice of environment.
