Unless the interface is straight C (or you're willing to write a native wrapper), you'd have to reimplement all the bits that com4j and jacob have implemented to support different aspects of COM.

JNA has nothing built-in to help you with COM types or dispatch interfaces, so you'd likely get more mileage out of tweaking com4j or jacob to get what you want.

I need to access a COM object (SAPI 5.3, Microsoft’s Speech API) from Java. I’ve been looking at some Java-COM integration tools. Com4j apparently doesn’t handle some aspects of SAPI that I need. Jawin doesn’t seem to be supported anymore. Jacob is still a possibility, but it’s a little fuzzy whether it handles the necessary events/callbacks correctly without leaking.

So I’m wondering about going a little lower-level with JNA. How reasonable is it to use JNA to access a COM object?
