Threads in Linux show up as processes when using 'ps' or 'top'.

But the code has only a infinity loop and doesn't create any thread

Try putting libMsgImpl.so in /usr/local/java/jre/lib/i386/ (or
wherever you have your javaVM located)

cp libMsgImpl.so /usr/local/lib/javanative/

I follow your instruction and put libMsgImpl.so in
/usr/local/jdk118_v1/bin/i686/native_threads, and
/usr/local/jdk118_v1/lib/i686/native_threads, and
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/jdk118_v1/lib/i686/native_thread

But the same problem is still there. I think libMsgImpl.so is loaded OK,
otherwise
error will be like "libMsgImpl.so not found". The problem is why I couldn't
call a native
function declared in a class other than java application's public class.
