Hi,

Iam created a desktop
login application using swings.
pls observe the following code:


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

class LoginDemo{
JButton SUBMIT;
JFrame f;
JLabel label1,label2;
final JTextField text1;
final JPasswordField text2;
LoginDemo(){
f=new JFrame();
f.getContentPane().setLayout(null);
label1 = new JLabel();
label1.setText("UserName:");
label1.setBounds(400,50,100,20);
text1 = new JTextField(25);
text1.setBounds(500,50,100,20);
label2 = new JLabel();
label2.setText("Password:");
label2.setBounds(400,80,100,20);
text2 = new JPasswordField(25);
text2.setBounds(500,80,100,20);
SUBMIT=new JButton("Login");
SUBMIT.setBounds(500,110,100,20);

f.add(label1);
f.add(text1);
f.add(label2);
f.add(text2);
f.add(SUBMIT);
f.setSize(1024,768);
f.setVisible(true);
SUBMIT.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
String value1=text1.getText();
String value2=text2.getText();
String user1="";
String pass1="";
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection con = DriverManager.getConnection("jdbc:odbc:msdesktop");
Statement st = con.createStatement();
ResultSet res = st.executeQuery("SELECT * FROM test where Empname='"+value1+"' and Emppassword='"+value2+"'");
while (res.next()) {
user1 = res.getString("Empname");
pass1 = res.getString("Emppassword");
}
if(!value1.equals(user1) && !value2.equals(pass1)) {
JOptionPane.showMessageDialog(null,"Incorrect login or password","Error",JOptionPane.ERROR_MESSAGE);
text1.setText("");
text2.setText("");
}
else if(value1.equals("")){

Connection conn = DriverManager.getConnection("jdbc:odbc:msdesktop");
PreparedStatement pstmt = conn.prepareStatement("insert into logininformation(username,logindate,logintime) values(?,?,?)");
pstmt.setString(1, value1);
java.sql.Date sqlDate = new java.sql.Date(new java.util.Date().getTime());
pstmt.setDate(2, sqlDate);
java.sql.Time sqlTime = new java.sql.Time(new java.util.Date().getTime());
pstmt.setTime(3,sqlTime);
/*java.sql.Timestamp sqlDate = new java.sql.Timestamp(new java.util.Date().getTime());
pstmt.setTimestamp(2, sqlDate);*/
pstmt.executeUpdate();
pstmt.close();
conn.close();
JOptionPane.showMessageDialog(null,"Login Successful");
}
catch(Exception ex){}
}
}
catch(Exception e){
System.out.println(e.getMessage());
}
}
});
}
public static void main(String arg[]) {
LoginDemo frame=new LoginDemo();
}

Hi Friend,

Try the following code:

import java.io.*;
import java.util.jar.*;

public class CreateExe {
public static int buffer = 10240;
protected void createExeArchive(File jarFile, File f) {
try {
byte b[] = new byte[buffer];
FileOutputStream fout = new FileOutputStream(jarFile);
JarOutputStream out = new JarOutputStream(fout, new Manifest());

if (f == null || !f.exists()|| f.isDirectory())
System.out.println();
JarEntry addFile = new JarEntry(f.getName());
addFile.setTime(f.lastModified());
out.putNextEntry(addFile);

FileInputStream fin = new FileInputStream(f);
while (true) {
int len = fin.read(b, 0, b.length);
if (len <= 0)
break;
out.write(b, 0, len);
}
fin.close();

out.close();
fout.close();
System.out.println("Jar File is created successfully.");
} catch (Exception ex) {}
}
public static void main(String[]args){
CreateExe jar=new CreateExe();
File f = new File("C:/LoginDemo.java");
File file=new File("C:/LoginDemo.exe ");
jar.createExeArchive(file, f);
}

}

Thanks
