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 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. But nothing helped.
Any help is appreciated!!!
Cheers,
Karsten
