This error message *looks* like one that we have when trying
to use a pure java driver inside a browser applet. It is due
to a Comm API bug when used into a Java2 (1.2 or 1.3) plugin.
There is a workaround, see one of my previous post on this issue:
http://www.opencard.org/archive/opencard/1374.html
There is also good news, it's that if you can use Solaris or Linux:
this bug has been fixed in the latest version of Comm API (see
an other post: http://www.opencard.org/archive/opencard/1462.html ).
If you are stuck with Win$$, there is still the workaround.
Now, I haven't tried to use the stockbroker demo, there might be a
completely different cause to your problem.. Also I think there is
an updated version of the OCF demos (Thomas Schaeck has posted a
message on this) at http://www.opencard.org/SCJavaBook/download.shtml
Hope it'll help.
Cheers,
Christophe.
