JNI and web services

[Raul Gutierrez Sanchez]

Hi Matthew,

libfoo.so must be placed in a directory listed in the library path, 
which is a list of directories that the Java runtime system searches 
when loading libraries. Make sure that the name of the directory where 
the libfoo.so library lives is in it. You can also change the library 
path. If you use a UNIX-like system (as it seems), you have to add the 
directory containing libfoo.so to your system $LD_LIBRARY_PATH (see the 
following link for more information: 
 http://java.sun.com/docs/books/tutorial/native1.1/stepbystep/_setlibpath.html 
).

Cheers,

Raúl
