Error 8000ffff Invocation failed

[loussai]

Hello,

I used line command in order to generate my classes from ocx and when i tried to execute code, i have this error
=> " com4j.ComException: 8000ffff Invocation failed: (null) : Défaillance irrémédiable : .\com4j.cpp:82"

My main code :
_DSoftPhone softphone = ClassFactory.createSoftPhone();
softphone.initialize("", "0019001", "0019001", "srvfr01-0001:4063"); //error on this line

I think my working environnement is well configurated. I'm working with 64bits machine

Can you help me ?
Thanks
