Hello,
I am working with an applet that gets the smartcard via event
notification (cardInserted and cardRemoved methods).
When It runs as application it works fine but when I try to run it as
applet I get the following error in the Java Plug-In console:
java.lang.NoSuchMethodError:
opencard.core.terminal.CardTerminalRegistry: method
setObserver(Lopencard/core/terminal/Observer;)V not found
at
opencard.core.event.EventGenerator.getGenerator(EventGenerator.java:101)
at ParkingApplet.register(ParkingApplet.java:540)
at ParkingApplet.init(ParkingApplet.java:120)
at sun.applet.AppletPanel.run(Compiled Code)
at java.lang.Thread.run(Thread.java:479)
when doing the event registration.
The code I am using is the proposed on the OCF 1.2 documentation.
This is the process we follow:

We make a jar that contains Eventos.class and we sign it. When we try to
run
it from an applet the messages from
the java console are:

Have you tested an applet accessing OCF using the 1.2 version?
Does anybody know something about this error?
Cheers,
