Can you send me more info on the use case.. and I will try and recreate
it? In the mean time.. tell me if the patched jar file at:
http://bkearney.fedorapeople.org/libvirt-0.4.0-PATCH.jar
works. You will need to download this and copy it into
/usr/share/java/libvirt-0.4.0.jar

Hi everyvody,
I'm developing a new API based on libvirt.
I'm currently stucked using getSchedulerParameters, always is returning a
nullpointerexception, no matter which Xen Domain I'm passing to the
function.
Enclosing both the code and the error console:
public int getCPUPriority(String name) {
int res=-1;
try {
Domain d = getDomain(name);
SchedParameter[] pars = d.getSchedulerParameters();
Hum, it seems
Domain.getSchedulerParameters()
does
SchedParameter[] returnValue = new SchedParameter[0];
and
public static SchedParameter create(virSchedParameter vParam) {
SchedParameter returnValue = null;
switch (vParam.type) {
case (1):
and the create method getting there gets a null pointer as the
initialization argument, which it first dereference ...
so not surprizing looking at the code, maybe Bryan has an idea of what
is going on there, I'm a bit lost in this initialization process ...
Daniel
for (SchedParameter pri : pars) {
if (pri.field=="weight")
res=Integer.parseInt(pri.getValueAsString());
}
} catch (LibvirtException e) {
log.error(" Error: getting CPU priority of \""+name+"\"." +
e.getClass());
e.printStackTrace();
}
return res;
}
