AcitveX components obviously depend on the operating system and are
not run by the VM. Java is not designed to do this. You may have a
couple options:
1. Convert the Java applet to a servlet and use Internet Explorer as
your servlet container. You can then POST data to the activeX control
or to the servlet. You can even embed the ActiveX control in a JSP
page if you wish.
2. Write a container for the ActiveX control as a win32 executable or
dll and invoke it from java. You can either exec() it, or use the
Java Native Interface (JNI) to wrap calls to a dll.
Both of these are hacks and you should use MFC, VB, or something
better suited for interfacing with ActiveX. Microsoft may provide a
way to do this with their VM, but I am unfamiliar with anything
outside Sun's standards in this respect.
