java - Customize the uninstaller in IZPack -

-

currently have installer , uninstaller application , problem during uninstallation. i.e if give command "java -jar uninstaller.jar" uninstall application 1 pop-up 1 checkbox message "force deletion of /opt/app(this installed path)" , 2 buttons: uninstall , quit.

the problem if don't check checkbox , click on uninstall button, says "uninstall successful", installed path not deleted , uninstall folder deleted.

if check checkbox , click on "uninstall" button, go fine.

so, prefer if check checkbox uninstall button should enabled, in other cases should disabled i.e when run uninstaller (java -jar uninstaller.jar) uninstall button should come disabled.

can please me out issue?
