Hello!

When i try to start http://webstart.buergerkarte.at/mocca/ out of my Firefox 3.5.8 (Popup is opening where i can choose "Open with: OpenJDK Java 6 Web Start) the screen with Bürgerkartenumgebung appears, and some files are downloading but then the window disappears.

So i saved the file mocca.jnlp on my disk and i started it from there (starting nautilus from console, double klick on mocca.jnlp in nautilus) - here i get also the screen Bürgerkartenumgebung, but it disappears, and on the console i get this message:

So i downloaded the newest version from http://egovlabs.gv.at/frs/download.php/208/BKUWebStart-1.2.13.zip

When i extract the zip and start it from nautilus i get this error:
---------------------------

So what is the problem here? is it my system (Ubuntu 9.10 amd64)? I want to do my Lohnsteuerausgleich but i can't start the app on https://finanzonline.bmf.gv.at/ - the java-app there tells me: "Fehler: Es konnte keine PC/SC-Schnittstelle gefunden werden"

If i choose Lokale BKU i'm getting redirected to: https://127.0.0.1:3496/https-security-layer-request :(

Also i downloaded and tried trustDesk Basic 2.8.1 for Linux ( http://update.buergerkarte.at/download/Linux/tdb281_x86_32bit.tgz ) - this app finds on the PC/SC Schnittstelle ( GemPlus GemPC Twin 00 00 ) the reader - but it finds no CT API - so any suggestions how i can do my lohnsteuerausgleich?
