Hi!

I guess the only way of communicating with COM from Java is using JNI. You can write a DLL transforming native functions calls into COM-methods calls and therefore use COM components.

If you don't really want to code a lot you can use a simple tool:

JCom - Yes:

"Some COM objects have a UI (commonly known as ActiveX controls.) EZ JCom can also be used to access such COM objects, by embedding them in an AWT or a Swing program."

If I'm not mistaken, the best road to Java with DLL's and OCX's is to use Microsoft's Visual J++ or J# or move to C#, since all these environments have wizards and other tools that automate the whole process of incorparating Window's based technologies in Java. One point to remember though is that once this path is taken, the programs you create are no longer truely Java or rather 100% pure Java.

Sorry dude, but that's how it goes... a Programmer's responsability is to getting the job done, not just to grand ideals ;)

And I don't get any points even though my idea is probably the most practical? ;)
