I would like to get some comments on an initial cut of the java bindings

good enough to be criticized. In addition, if there are features

the feedback on that.
Thanks for your work!
I pulled from git, it compiles fine when provided with jna.jar - couldn't find
that except in my Eclipse 3.4 path.
When using it with my tiny test application (which works fine with the JNI
version), it first complains that /etc/pki/CA/cacert.pem can not be found. As
I installed libvirt from source, it's in /usr/local/..., working fine with
JNI. So I did a symlink workaround for now.
Where did you see this complaint? Also.. what is your LD_LIBRARY_PATH
set to when running this.
But fixing that, it doesn't work either:
libvir: error : invalid argument in could not parse connection URI

Code is:
...
conn = new Connect("xen://node02", false);
...
which works fine with JNI.
Does
conn = new Connect("xen://node2/", false) ; do any better?
When I use the test class (directly on a node where libvirtd is running, or
remote, it doesn't matter), connections to the test driver are refused,
although some test information seems to be gathered, and connecting with
virsh works perfectly:
Acutally.. this is bad output. I bet I left the call with the
defaultAuth in there. Can you verify that there are 2 open calls in the
code I sent?
Thanks!
