How to get Disks, Aggregate and LUNs information of storage system using netapp ontap api (8.1) and java?

Question

I want to get information about Disks, Aggregates and LUNs using netapp ontap api 8.1. I am able to get list of volumes using following code:

VolumeListInfoIterStartRequest volumeListReq = new VolumeListInfoIterStartRequest();
    Iterator<VolumeInfo> volumeIter = apirunner.iterate(volumeListReq,10);
    VolumeInfo volume ;

   while(volumeIter.hasNext()) {
         System.out.println("------------------------------------------------");
         volume = volumeIter.next();
         System.out.println("Name               : " + volume.getName()); 
         System.out.println("Type               : " + volume.getType()); 
         System.out.println("State              : " + volume.getState());
         System.out.println("Total size (bytes) : " + volume.getSizeTotal());
         System.out.println("Used size (bytes)  : " + volume.getSizeUsed());
         System.out.println("Total disk count is .. "+ volume.getDiskCount());
         System.out.println("sysinfo is .. "+ volume.getSis());
         System.out.println("Total available size .. " + volume.getSizeAvailable());
         System.out.println("UUID is .. "+volume.getUuid());
         String vol = volume.getName();
         System.out.println("snapshot is "+ volume);
         System.out.println("------------------------------------------------");

     }

But when I try to use api for LUN exactly same as above I get error in iterate function. My code is:

LunListInfoRequest lunreq = new LunListInfoRequest();
     System.out.println("luninfo is .. " + lunreq);

     Iterator<LunInfo> lunInfoIter = apirunner.iterate(lunreq,10);

I got error in last line.

How do I get information about Disks, aggregates and LUNs??
