The file not found was cacert.pem, not the *.so - so I don't think 
LD_LIBRARY_PATH matters here? 

Anyways, the problem about

	conn = new Connect("xen://node02", false);

was my fault - I forgot wiping an old apt-installed version of libvirt before 
compiling libvirt-java-jna. It works now, but there seems to be a massive 
typo somewhere; when I start my small application, it can't 
find "liblibvirt.so" (sic!) and exits. 

# find /usr -name "libvirt.so*"                                                             
/usr/local/lib/libvirt.so.0.6.5
/usr/local/lib/libvirt.so.0
/usr/local/lib/libvirt.so

(ld cache is up to date, checked /etc/ld.so.cache)


# ln -s /usr/local/lib/libvirt.so /usr/local/lib/liblibvirt.so    
# ldconfig

...and it works! ;-)

This here?

...
 //For testing the authentication
 ConnectAuth defaultAuth = new ConnectAuthDefault();

try{
conn = new Connect("test+tcp://localhost/default", defaultAuth, 0);
....
