Probleme mit den Webstart Demos

[mzeller]

Hallo,

wir sind noch immer im Entscheidungsprozess, ob JVx ja oder nein.

Leider kann ich eure Demos einfach nicht starten. Ich habe es schon mit verschiedenen Java-Versionen versucht, die Sicherheitseinstellungen geändert - bisher ohne Erfolg.

Ich bekomme beim Start der ERP-Demo folgende Exception:

Code: Select all

Ich bin auf Ubuntu 14.04 LTS mit folgender Java-Version:

Java Web Start 11.45.2.14
JRE-Version verwenden 1.8.0_45-b14 Java HotSpot(TM) 64-Bit Server VM


Habt ihr irgendeine Ahnung, woran das liegen kann?

Huh, ja das Problem kommt mal vom LaF und wir hatten das auch schon. Wir haben dann den Window Manager geändert, weil Unity Probleme machte. Dann funktionierte es. Wir haben einfach durchprobiert.
