Thanks a lot for the Help , but it is still not working.
when the JFileChooser open then if I click a file name once and then again - it's name becomes editable , and that's what I need to prevent.there is no need for right click to do this action.
thanks,

Shouldn't file-permissions be handled by the OS?
Why shall you manage it from your app, when the user may change filenames from other apps as well?
