Connect to a remote host using JSch

Hi,
I have a form which takes user@hostname and password as input. I have written the following code:

package my.initPckg;
import com.jcraft.jsch.*;

public class PmtGui extends JFrame {

private JPanel contentPane;
	private JTextField textFieldHN;
	private JTextField textFieldPW;

/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					PmtGui frame = new PmtGui();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

/**
	 * Create the frame.
	 */
	public PmtGui() {
		setTitle("Performance Monitor Tool for 8950 SAM");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		JLabel lblHostName = new JLabel("Host Name:");
		lblHostName.setFont(new Font("Tahoma", Font.BOLD, 12));
		lblHostName.setBounds(117, 83, 83, 14);
		contentPane.add(lblHostName);
		
		JLabel lblPassword = new JLabel("Password:");
		lblPassword.setFont(new Font("Tahoma", Font.BOLD, 12));
		lblPassword.setBounds(117, 127, 67, 14);
		contentPane.add(lblPassword);
		
		textFieldHN = new JTextField();
		textFieldHN.setBounds(210, 81, 122, 20);
		contentPane.add(textFieldHN);
		textFieldHN.setColumns(10);
		
		JButton btnConnect = new JButton("Connect");
		btnConnect.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent arg0) {
				String host = textFieldHN.getText();			
				String passwd = textFieldPW.getText();
				String user = host.substring(0, host.indexOf('@'));
				host = host.substring(host.indexOf('@')+1);
				try {
					JSch jsch=new JSch();
					Session session=jsch.getSession(user, host, 22);
					session.setHost(host);
					session.setPassword(passwd);
					session.connect();
					
					Channel channel = session.openChannel("shell");
					channel.setInputStream(System.in);
				    channel.setOutputStream(System.out);

channel.connect();
				}
				catch (Exception e){
					System.out.println(e);
				}
				
			    
			}
		});
		btnConnect.setBounds(117, 193, 89, 23);
		contentPane.add(btnConnect);
		
		JButton btnCancel = new JButton("Cancel");
		btnCancel.setBounds(234, 193, 89, 23);
		contentPane.add(btnCancel);
		
		JLabel lblConnectToServer = new JLabel("Connect to Server");
		lblConnectToServer.setFont(new Font("Tahoma", Font.BOLD, 13));
		lblConnectToServer.setBounds(148, 29, 146, 14);
		contentPane.add(lblConnectToServer);
		
		textFieldPW = new JPasswordField(20);
		textFieldPW.setBounds(210, 125, 122, 20);
		contentPane.add(textFieldPW);
		textFieldPW.setColumns(10);
	}

}

It is throwing an exception. May I know what has to be corrected?

Are you going to tell us what exception that was, and in which line of code it happened, or are we supposed to guess?

Oh sorry. Here's the exception:

So the problem is solved now?

No. It's not solved.

Well, what do you think the error message is trying to tell you?

I guess it is not able to locate the host. Is it right?

Correct. Is that host name resolvable on the machine where you're running the code? It sure is not on mine.

Yes, the hostname is resolvable. When I tried out this out it is working fine. But when I tried to write something on my own, I is not working out.

Hi, it is working now. I followed this link. But I am not able to figure out what exactly has been done so that my code is working fine now.
