I think we need specifics: what code operation and what security
exception did you receive?
=A0
This is probably not Java3D related, so if you don't find the answers
here you may want to try a more generic Java listserv.

Subject: [JAVA3D] Applet security
Hello everybody:=20
This days I have been implementing a little Java3D applet including it
in a Web Server.=20
When I have launched remotely ( or not ) the applet I have received
several security exceptions.=20
I am suposing this things:=20
=A0=A0=A0=A0=A0=A0=A0 - When I launch a Java3D code inside an applet I =
only include in
the codebase of the applet the jar file with my own implementation, not
including Java3D core .jar files.
=A0=A0=A0=A0=A0=A0=A0 - I supose that then the remote machine that is =
running the
applet downloaded from the server needs to have installed the Java3D
core locally.
=A0=A0=A0=A0=A0=A0=A0 - I supose too that Java3D core will run then =
(locally too)
OpenGL or DirectX native code.=20
So the idea could be that if I ensure permissions for the codebase
coming in from the remote Web server the applet will run OK.
So I use the java policytool command and I give permissions for the
codebase coming from http://remoteServer/code_path/-
I reach in this moment my first problem:=20
=BFWich permissions should I give to the applet codebase?=20
I have been trying giving the exactly needed permissions but they were =
a
lot and I became bored...=20
I had to give permission for Runtime, for Property and I noticed that
for every library or dll method of Java3D I had to give another new
permission.
So I decided to give AllPermisions for this codebase.=20
But it had no effect.=20
Trying more I found the worst solution ever known: To give AllPermision
for ALL the codebase I could receive.=20
And it worked correctly.=20
Anyway I think that is not a good decision, so if anyone has been
suffering the same problems and has found a better solution please let
me know. I said it before, I have hunger of knowledge.
Forgive me about my spaggheti english, I am young and yet I have time =
to
learn it better.=20
Merry Christmas and Happy New Year.=20
