hello,

I have created an Event-Sink class in C++ to handle COM-Events and it
works well in a MFC-application.

But if I create a DLL to use this Event-Sink-Class with the JNI then
the callback function of the event-sink is not called. The COM-Server
tells me that it is "overloaded" when it fires the event. It seems to
me that it "hangs" somehow in the JVM.

here some pseudo code:

in Java:

class Test {
 public static native void nativeFunction();
 public static void main(...) {
  nativeFunction();
  //during sleeping I fire the "event"
  Thread.sleep(30000);
}
}

in the DLL:

class EventSink : public IDispatch
{
 ...
 HRESULT __stdcall Invoke(...) {
    //just exit application
    exit(0);
    return S_OK;
 }
 ...
};

JNIEXPORT void JNICALL ...nativeFunction(...)
{
  //initialize COM
  CoInitializeEx(NULL, COINIT_MULTITHREADED);
  //create COM object with CoCreateInstance(...)
  //get IConnectionPointContainer of the object
  //get IConnectionPoint* connectionPoint
  //advise sink to connectionPoint
  EventSink* sink = new EventSink();
  connectionPoint->advise(sink, &cookie);
  ...
}

what is wrong in the code?

thanks in advance!
