I have a simple Applet application and my code creates ImageIcon objects from the same url from the Applet. When I run the application, I get a message about unrestricted access, it scares the user.

How I configure my Applet or my JNLP to only show specific restriction messages?

Edited After all, I refactor my code and find ways to load image correctly. To load image from JAR: http://docs.oracle.com/javase/tutorial/uiswing/components/applet.html#images. To load image from Applet: imageIcon = new ImageIcon(getImage(getCodeBase(), "image/image_name.png"));

Beyond the more specific permissions shown for the JNLP API services, Java does not offer any finer permission gradations than all-permissions, j2ee-application-client-permissions or sand-boxed (no security element).

However it seems this warning is seen due to a bug linked by the OP.

Netbeans Bug 227169 - java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "modifyThreadGroup")

  • Andrew, do I need add permission for this? *... URL url = new URL(codeBase, imageName); return new ImageIcon(url); ..* For example, my applet run on *http://www.mvbos.com.br/blank_colony/* and I try to loag image from *http://www.mvbos.com.br/blank_colony/image/* – Marcus Becker Apr 09 '13 at 01:46
  • That should work in a sand-box, so long as `imageName` is not something ridiculous. – Andrew Thompson Apr 09 '13 at 23:47
