Signed Jar & doPrevilage doesn't solve access control exception

[OGlock]

I am trying to invoke the file chooser option and get the filename as a input. But I am getting the java.AccessControlException. This works fine when I launch the applet with a webbrowser but throw exception when tried with appletviewer.I have tried the following [*]Signed the JAR using keytool and jarsigner JDK1.6.24[*]Use AccessController.doPrivileged.But i am still getting the same exception as follows.\[code\] Exception in thread "AWT-EventQueue-1" java.security.AccessControlException: access denied
