Independent disk

Hi all,

I'm trying to create/get/delete an independent disk using vcloud sdk for java.

Here is a working snippet of code:    

Disk newDisk = vdc.createDisk(createDiskParameters());

where:
   private DiskCreateParamsType createDiskParameters() {

      DiskCreateParamsType diskCreateParams = new DiskCreateParamsType();

      DiskType diskType = new DiskType();

      diskType.setName(DISK_NAME);

      diskType.setSize(DISK_SIZE);

      diskCreateParams.setDisk(diskType);

      return diskCreateParams;

   }

The creation step is ok, but the deletion fails with java.lang.NullPointerException using: Disk.delete(client, newDisk.getReference());

In fact, also vdc.getDiskRefs() returns an empty collection of Refs

Also I'd like to be able to setStorageProfile using diskType.setStorageProfile(ReferenceType value)

but I don't know how to list all the available StorageProfiles on my vcd. In fact vdc.getVdcStorageProfileRefs() returnsan empty collection of Refs as well.

Can you help me?

Thanks,

Andrea
