I'm having a hell of a time trying to make a login form.
This is what I have at the moment....
import javax.swing.*;
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
class LoginDemo extends JFrame{
JButton SUBMIT;
JLabel label1,label2;
final JTextField text1,text2;
LoginDemo(){
setTitle("Login Form");
setLayout(null);
label1 = new JLabel();
label1.setText("Username:");
text1 = new JTextField(15);
label2 = new JLabel();
label2.setText("Password:");
text2 = new JPasswordField(15);
SUBMIT=new JButton("SUBMIT");
label1.setBounds(100,100,100,20);
text1.setBounds(200,100,200,20);
label2.setBounds(100,130,100,20);
text2.setBounds(200,130,200,20);
SUBMIT.setBounds(200,160,100,20);
add(label1);
add(text1);
add(label2);
add(text2);
add(SUBMIT);
setVisible(true);
setSize(500,300);
SUBMIT.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
String value1=text1.getText();
String value2=text2.getText();
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("select * from userInfo where username='"+value1+"' and password='"+value2+"'");
int count=0;
while(rs.next()){
count++;
}
if(value1.equals("") && value2.equals("")) {
JOptionPane.showMessageDialog(null,"Enter login name or password","Error",JOptionPane.ERROR_MESSAGE);
}
else if(count>0){
System.out.println("Login Successful");
page.setVisible(true);
}
else{
text1.setText("");
text2.setText("");
System.out.println("Invalid Login name or password");
}
}
catch(Exception e1){}
}
});
}
public static void main(String arg[]){
new LoginDemo();
}
}When I hit my submit button, absolutely nothing happens...
Help?
Thanks
