I have a Webstart app deployed locally on a Tomcat server. It's signed using my own generated certificate,a and only one JAR file is used containing two classes - no 3rd party JARs or anything like that. It's a simple Swing application which creates a Preferences object like so:
Preferences prefs = java.util.prefs.Preferences.userNodeForPackage(TicTacToe.class);
I access the code like this:
When the app runs, I don't get the Security warning dialog which I expect for a signed JAR. The app runs automatically and I see this exception in the console:
Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.lang.RuntimePermission preferences)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.util.prefs.Preferences.userRoot(Unknown Source)
at java.util.prefs.Preferences.userNodeForPackage(Unknown Source)
My JNLP file seems correct and has the
block to grant all permissions.
What could be going wrong here? From what I've read, a self-signed cert should work, and should show a Security dialog warning not to run the application. I'm running with Java Web Start 1.5.0_02.
I'd appreciate any ideas!
