    // on a virtual machine, like cancel or finalize:

}
catch (Exception e)
{
    System.out.println(e.getMessage());
}
}
}

after executing this in root but it is giving an error that "ONE_AUTH file
not present..
plz tell me I am doing right or wrong because I just installed netbeans on
that system and added org.opennebula.client.jar and running above apps.
how it will interact with opennebula???
