Thread: Having issues with simple logIn --- insert new user to th db

Hello,

I have a slight problem with a simple swing program.

I created a simple program for user to logIn this part is working. But when I want to register new user into db it doesn't work.

Can you pls look at my code nd help me. I tried to search, but it's just getting confusing. Thank you very much.

butReg.addActionListener(new ActionListener(){
			public void actionPerformed(ActionEvent e) {
 
 
				String username =JOptionPane.showInputDialog(null, "Enter new username" );
				String pass = JOptionPane.showInputDialog(null, "Enter new password" );
 
				try{
 
				String insert = ("INSERT INTO login (account) " + "(Username, password)" + "VALUES ('" + username + "', '" + pass + "' )");
 
				stat2 = (Statement) con.createStatement();
				stat2.executeUpdate(insert /*"INSERT INTO users" +  "(Username, Password ) VALUES" + " (?,?)"*/);
 
 
				}
 
 
				catch(Exception ex){
 
				}
 
			}	
		});
 
	}

No errors at all,

but when i look into my db the new values aren't there. :/ it's not updating my db.
