如何使用NetApp SDK和Java获取卷列表？

Question

I want to get volumelist on storage system using netapp manageability sdk and java. I am able to get only version and type of storage system. I am running a sample program given with sdk, but it gives me null values...

Here is a code...

import com.netapp.nmsdk.client.ApiRunner;
import com.netapp.nmsdk.client.ApiTarget;
import com.netapp.nmsdk.client.ApiTarget.TargetType;
import com.netapp.nmsdk.ontap.api.volume.VolumeInfo;
import com.netapp.nmsdk.ontap.api.volume.VolumeListInfoIterStartRequest;
import com.netapp.nmsdk.ontap.api.volume.VolumeListInfoIterStartRequest;
import java.util.Iterator;
import java.util.List;

public class VolList {

public static void main(String[] args) { 

    if (args.length < 3) {
        System.err.println("Usage: VolList <storage-system> <user> <passwd> [<volume>]");
        System.err.println("    Note: This sample code will list the volume information of a 7-Mode Storage system.");
        System.exit(1);
    }
    try {
        ApiRunner runner = new ApiRunner(ApiTarget.builder()
            .withHost(args[0])
            .withUserName(args[1])
            .withPassword(args[2])
            .withTargetType(TargetType.FILER)
            .useHttp()
            .build());

        VolumeListInfoIterStartRequest volListReq = new VolumeListInfoIterStartRequest();
        if (args.length > 3) {
            volListReq.setVolume(args[3]);
        }

        Iterator<VolumeInfo> volumeIter = runner.iterate(volListReq, 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("------------------------------------------------");
        }
    } catch(Exception e) {
        e.printStackTrace();
    }
}
}

how should I able to get volumelist using netapp and java?
