[libvirt] Connection using Java

Hi, I am using java to connect to the xen, but my class is throwing a exception. Does anyone know what is happening? public class TestConnection { public static void main(String[] args) { Connect conn = null; try { conn = new Connect("xen+ssh://root@192.XXX.XXX.XX/", true); libvir: RPC error : End of file while reading data: nc: invalid option -- 'U' nc -h for help: Input/output error exception caught:org.libvirt.LibvirtException: End of file while reading data: nc: invalid option -- 'U' nc -h for help: Input/output error level:VIR_ERR_ERROR code:VIR_ERR_SYSTEM_ERROR domain:VIR_FROM_RPC hasConn:false hasDom:false hasNet:false message:End of file while reading data: nc: invalid option -- 'U' nc -h for help: Input/output error str1:%s str2:End of file while reading data: nc: invalid option -- 'U' nc -h for help: Input/output error str3:null int1:-1 int2:-1 Thanks, Felipe -- *-- Felipe Oliveira Gutierrez* *-- **lipe.82(a)gmail.com* <lipe.82(a)gmail.com&gt; *-- https://sites.google.com/site/lipe82/Home/diaadia*
