oic, it was me.
[code]permission java.util.PropertyPermission "j3d.stereo", "read"; //  added by lookang[/code]
add this line to C:\Program Files\Java\jre1.5.0_16\lib\security\java.policy
i added at the bottom of the codes

and if that didn't work[/s]

add  the same line to C:\Program Files\Java\jre6\lib\security\java.policy
i think this is the solution to the 3D java

i used Jedit to edit them

[s]method 2:
1 download the attachment java.zip
2 unzip the file, it is called java.policy
3 copy file into C:\Program Files\Java\jre6\lib\security\java.policy
3.5 optional* rename java.policy into java.policy~ in case you want the old file back
4 say yes to copy and replace file depending on whether it is replace or just copy new[/s]

BOOM! Java 3D on Ejs Web applets  ;D ;D
attached is the java.policy for windows xp system
