When I try to run the HelloJava3Da sample from the Java 3D tutorial inside
VisualAge (in AppletViewer) I get this message:
java.lang.ExceptionInInitializerError: java.security.AccessControlException:

java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)

java.applet.Applet
sun.applet.AppletPanel.createApplet(sun.applet.AppletClassLoader)
void sun.applet.AppletPanel.runLoader()
void sun.applet.AppletPanel.run()
void java.lang.Thread.run()
This same example runs perfectly when it is exported. Does anyone know a way
to allow Java 3D and VisualAge to work properly?
Thanks in advance
