libvirt users - Oct 2012 - libvirt Java to connect at the XEN

Hi people, I am new using libvirt for Java

I created a class to test my conecction with XEN, but it is throwing a
exception that I can't figure out how I solve this.
Does anyone knoe how to configure it correctly?
I cat use this class from the command line:
$ javac -classpath /usr/java/jdk1.6.0_34/bin/libvirt-0.4.9.jar test.java
$ java -classpath
.:/usr/java/jdk1.6.0_34/bin/jna.jar:/usr/java/jdk1.6.0_34/bin/libvirt-0.4.9.jar
test
and it connect to the XEN.

But when I put the code on my eclipse it doesn't work any more.

...
conn = new Connect("xen:///", true);
....
