Question about JNI and Java and C

[cracklepopflash]

So we can use JNI to allow the Java code to call C code. But I am wondering if there's a way to do the opposite. Like when an event on the C side happens, it can call the appropriate Java method. How would I do that in general?

What kind of C events are we talking about? If it's COM, there are ways of wrapping COM objects for use with Java.

You can also call Java methods directly from native code. I haven't done it myself, but I found this documentation:

That said, I think you're probably better off doing as much of your coding as possible in Java, and using JNI only for the lowest-level OS-dependent stuff that can't be done any other way. If you're fluent in C, Java is not that steep a learning curve.
