Examples vary depending on what type of ActiveX control (such as COM+ or UI controls) and which direction you want to communicate (Java-to-ActiveX, ActiveX-to-Java) as well as what tools you are using in conjunction with the ActiveX and Java (some Java Web Servers support ActiveX controls as Java objects).
I do agree that if you can avoid it, don't mix ActiveX (COM) with Java. I am having trouble getting my Java objects to act as COM objects and the Packager documentation that Sun provides is not very helpful.
