HELP!!!! verifying userID & Password from Applette

[ione walker]

I have been given an assinment by a Java teacher
to create a banking application where the first
screen will be the welcome to the program,
User Input of UserID & Password.
& an Submit & Cancel Button.
Once the Submit button is pressed the program
meeds to pull the UserID & Paswd from the
screen & compare it to information comtained
in a file.
If Ok go on to the next screen & iff not
refresh the screen & try again.
So far I have an ugly BUT working applet.
How the heck do I take the userid/pswd
& compair it to a file?

HELP!!!

Hi Ione,
Your problems will be much worse. You need to create an APPLICATION not an Applet to get the job done. An Applet has security restrictions that prevent it from performing I/O.
Before you try and overcome them, find out if an application will suffice.
If it can then you can use a cardLayout to hold the screens and only show the first card until the validation is passed.
Regards,
Manfred.

Is an Applette a french Applet? Or maybe a baby Applet?
Sorry, you can use a Dialog or a JDialog to get input from your user. You will want to use a JPassword field also.
Where exactly is the file that you are going to compare to supposed to be kept? Normally that would be on a remote machine, requiring a URL connection.
