Hello OCF-Gurus,
my goal is to write an applet with which user can sign html-forms.
As application it works perfectly, but when trying to use it as an applet I
get the following exception when trying to get a smartcard-instance:
>appletviewer -J-Djava.security.policy=policy index.htm
<---
Caught java.lang.NullPointerException: name can't be null while loading

object - no port identifiers found!

policy contains:

when I use the SUN 1.4 plugin for IE I get a somewhat shorter exception:
<---
com.gieseckedevrient.opencard.terminal.io.SerialIO::init: Cannot create tty
object, reason = [name can't be null].
opencard.core.terminal.CardTerminalException:

System:
Windows 2000
JBuilder 4
JRE 1.4
IE 6.0
Cardterminal: Giesecke&Devrient PCT 200 (Towitoko)
The opencard.properties-file is the same as for the application.
I am very new to this, if you need any additional information please ask.
Any hint is appreciated.
Many thanks in advance!
Frank
P.S.: I hope you don't get this twice, in my first attement I forgot to
