Hi there Mr. Tromey :)

Being that you're talking about loading shared objects with libgcj, I
have a question.

Question:
I have libsampNat.so which contains an CNI-based servic(not JNI) that I
compiled with gcj -shared.
How do I run gij in order to have sample.class loadLibrary("sampNat")
like the jni example gets loaded up in the gcj/JNI example in the gcj
faq.

The files in question are attached.

Thanks for taking the time.
