Trouble with simple CNI example

[Vinstrumentation - Alex Gardiner]

Hi

I am trying to learn how to use CNI with gcj.  I have moderate Java
experiance but little C++ experience.

When I copy the example for Version 3 in FAQ 6.1, it does not compile.  The
error is in the  sampNat line that with callSTLcode().  It tells me that
this is undeclared.

How do I declare it and how has this error occurred.  I am using version
3.3.3

Regards
