This is a rough little snippet that does what you want. Up to you to make it nicer.

        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        panel.add(new JLabel("Some error message"), BorderLayout.NORTH);
        JTextArea textArea = new JTextArea("Details about the error\n\rMore Details...");
        boolean detailsVisible = false;
        Object[] options = { "OK", "DETAILS" };
        int choice = 1;
        while (choice==1) {
            choice = JOptionPane.showOptionDialog(null, panel, "Title",
                JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[1] ) ;
            if (choice==1) {
                if (detailsVisible)
                    panel.remove(textArea);
                else
                    panel.add(textArea, BorderLayout.CENTER);
                detailsVisible = !detailsVisible;
            }
        }

>> but i wana tht below the 2 button the details part should be shown
Than you'll need to completely make your own panel.
Using JOptionPane doesn't allow you to place something under that buttons.

That shouldn't be too difficult.
The base idea is in the code I gave you:
add/remove an extra component in your panel whenever you press <Details>

Adding/ removing the component could be costly. What you could do is - keep a text-area for displaying the details, and make it invisible/ visible based on whether the user wishes to see the details or not. When you make it invisible, decrease the height of your container and when you make it visible, increase it back to its original height.

Adding/removing one simple component?

Well, just that adding/ removing a text-area is still expensive than just making it visible/ invisible.... nothing else ;-)
