pom.xml <--- includes jni-java and jni-native modules
jni-java <-- a jar packaging
jni-native <---- native packaging( dll ) make your it depends on

classname is wrong, it just be java format com.xuy.classname
Will fix up the example to be clearer.

For each platform, your will need to create a project for native compile
root
jni-java
native
pom.xml <--- use profile to trigger native build depending on os
src <------ put all your common native source here
win32
linux

I never tested with MinGW gcc, but accouding to Sun, you need msvc 6.0 to to
do JNI stuff
