I posted a patched jar file at:

http://bkearney.fedorapeople.org/libvirt-0.4.1-PATCH.jar

The only change was making the struct into a union per your comments. Can you let me now if this solves you NPE? It passes my tests.

Alright.. let me give it a try. I was not seeing the NPE in the tests I

ran.

Thanks for the update, Bryan, but the problem still persists. In my

setup (Xen hosts): Domain.getSchedulerParameters() still raises a NPE.

In libvirt.h, _virSchedParameter is defined as follows using a union for

the value:

struct _virSchedParameter {

char field[VIR_DOMAIN_SCHED_FIELD_LENGTH]; /* parameter name */

int type; /* parameter type */

union {

int i; /* data for integer case */

unsigned int ui; /* data for unsigned integer case */

long long int l; /* data for long long integer case */

unsigned long long int ul; /* data for unsigned long long integer case */

double d; /* data for double case */

char b; /* data for char case */

} value; /* parameter value */

};

I believe the Java mapping of virSchedParameterValue should be a Union

instead of a Structure:

public class virSchedParameterValue extends Union {...}

Frederic
