in the line (e.getSource == addbutton)

also can not resolve symbol
variable rs ( which is my Resultset that i have created in my code).

can any body help in solving my problem to retrieve and display the values from the table to the textfields.

Thanks in advance.

code starts:
========================================



import java.sql.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class sample1 extends JFrame implements ActionListener
{
public sample1()
{
super("Sample application");

// JPanel p = new JPanel();

JLabel empid = new JLabel("Employee id");

JLabel empnamelabel = new JLabel("Employee name");


JTextField id = new JTextField(20);

JTextField empname = new JTextField(20);

JButton addbutton = new JButton("Add");

Container c = getContentPane();

// c.add(p);


c.add(addbutton);
c.add(empnamelabel);
c.add(empname);
c.add(id);
c.add(empid);



addbutton.addActionListener( new ActionListener);
add( addbutton );




//load the JDBC-ODBC bridge driver


try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

}

catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
}


// Get the connection

Connection conn = DriverManager.getConnection("jdbcdbc:empdsn");

// create a statement object, resultset object and prepared statement to pass sql queries.

Statement st = conn.createStatement();

st.executeQuery("Select * from NAME");

ResultSet rs = st.getResultSet();


pack();
setVisible(true);

}


public static void main(String args[])
{

sample1 sam = new sample1(sam);


sam.addWindowListener(
new WindowAdapter() {
public void windowClosing( WindowEvent e ) {
System.exit( 0 );
}
}
);
}

}



public void actionPerformed(ActionEvent e)
{
if(e.getSource()==addbutton) {
try
{
while(rs.next())
{
id.setText(rs.getString(1));
empname.setText(rs.getString(2));
}
}
catch(Exception ee) {}

}
}


}

From a very quick look it would appear your first major problem is in the creation of addButton:

Code:

addbutton.addActionListener( new ActionListener);
add( addbutton );

The ActionListener is an interface and therefore you need to either provide a class which implements the interface in it's place or provide the implementation that you want for the ActionListener in place :

Code:

addbutton.addActionListener( new ActionListener(){

	public void actionPerformed(ActionEvent arg0) {
		//TODO Replace this with your actual implementation
		System.out.println("You have clicked add");
	}});
add( addbutton );

That will get you past the first hurdle but you have some other very serious issues with your code.

I would suggest you grab yourself a basic java book and work through that.
