dialog box warning

[tomo black]

hi, i have witten a GUI that requests user input. If the input is incorrect then a warning appears(using JDialog)to advise the user.
the problem is that if the user repeatedly enters incorrect input, then the same warning is produced many times. i would like for that warning to appear only once and for the GUI to become inactive until the warning message has been dealt with. At the moment the gui is still active when the warning is active.
i hope this problem is explained alright.
thanks in advance

It seems that you have see your JDialog as non-modal. With a non-modal dialog, user can still input on the background GUI. You can solve it by creating a modal dialog.
However, if you just want to show a warning message, why not use the static method provided by JOptionPane, like showWarningMessage()?
