You don't need to locate it at all as gcj doesn't need it at all when 
compiling to native (and then libgcj.so is used like other libraries 
for other apps) and gij should handle it quite well. If not, its a 
bug.

On Debian systems its installed as /usr/include/jni.h and package 
dependencies make sure that only one version of the libgcj devel 
packages is installed (e.g. only libgcj 3.4.2). What you should do is 
to use pkg-config and use the .pc file provided. I think it was first 
included in 3.4.0. I don't know if you wanna support older versions 
of GCJ at all.
