This is a bug in the 1.3.1 Beta Plugin. The path to the default Plug-In JRE contains spaces (c:/program files/javasoft/jre/. . .). That's causing permission problems (don't ask). To work around the bug, first uninstall everything, then install the 1.3.1 SDK, then install the 1.3.1 JRE in a directory not conatining spaces (like c:/javasoft) then re-install Java 3D. Or just use 1.3.0_02. -Paul > X-Accept-Language: en > MIME-Version: 1.0 > Content-Transfer-Encoding: 7bit > Date: Mon, 19 Mar 2001 15:19:20 +0100 > From: Karsten Fries <[EMAIL PROTECTED]> > Subject: [JAVA3D] Security exception with 1.2.1 > To: [EMAIL PROTECTED] > > Hi there, > > i just migrated to Jdk1.3.1 beta and J3D 1.2.1. > i use the 3d api in an applet using netscape/ie. > > now i have a problem, because i get some security exception > > java.lang.ExceptionInInitializerError: java.security.AccessControlException: > access denied (java.lang.RuntimePermission modifyThreadGroup) > at java.security.AccessControlContext.checkPermission(Unknown Source) > at java.security.AccessController.checkPermission(Unknown Source) > at java.lang.SecurityManager.checkPermission(Unknown Source) > at sun.applet.AppletSecurity.checkAccess(Unknown Source) > at java.lang.ThreadGroup.checkAccess(Unknown Source) > at java.lang.ThreadGroup.getParent(Unknown Source) > at javax.media.j3d.MasterControl$23.run(MasterControl.java:3044) > at java.security.AccessController.doPrivileged(Native Method) > at javax.media.j3d.MasterControl.<clinit>(MasterControl.java:3037) > at javax.media.j3d.VirtualUniverse.<clinit>(VirtualUniverse.java:206) > at javax.media.j3d.Canvas3D.<clinit>(Canvas3D.java:2728) > at java.lang.Class.forName0(Native Method) > at java.lang.Class.forName(Unknown Source) > > when initializing my Canvas3D derived class. > I tried to use the policytool (all permisions and runtime permissions and > reflect permissions) > and signed the jar file.
