Find and retrieve resources by VTMOS例子出问题

[WHW1984]

我看Tivoli的ncm_pdf_api_61.pdf文档，里面的Find and retrieve resources by VTMOS这个例子。
代码如下：
public void findAndRetrieveResourceByVTMOS()
{
ResourceManager rMgr;
ResourceContainerKey containerKey = null;
boolean subrealmsFlag = false;
String vendor = "*";
String type = "*";
String model = "*";
String os = "*";
try
{
rMgr = Connection.getInstance().apiSession.resourceManager();

// set up search criterion based on vendor/type/model/os
// setting a null value is the same as "*"
// for example setVendor(null) means the same as setVendor(*)
VtmosCriterion vtmos = rMgr.dataFactory().newVtmosCriterion();
vtmos.setVendor(vendor);
vtmos.setType(type);
vtmos.setModel(model);
vtmos.setOsVersion(os);

ResourceSearch rs = rMgr.dataFactory().newResourceSearch();
rs.setCriterion(vtmos);
rs.setResourceName(null);
// ArrayList<String> rTypeAL = new ArrayList<String>();
// rTypeAL.add(Resource.RESOURCE_COMMANDSET); // set resource type(s) as needed
// rs.setResourceTypes(rTypeAL);

ResourceContainerDescriptor realmRCD = rMgr.getContainer("root/3k");
if(realmRCD!=null){
containerKey = realmRCD.getKey();
}
rs.setStartingContainer(containerKey);
rs.setSubRealms(subrealmsFlag);

// now do the search
@SuppressWarnings("unchecked")
Collection<ResourceContentDescriptor> csDescs = rMgr.search(rs);//出错
if (csDescs == null || csDescs.isEmpty())
{
// handle case of no matches

} else
{
// for each descriptor, retrieve the corresponding CommandSet object
ArrayList<CommandSet> csColl = new ArrayList<CommandSet>();
Iterator<?> csDescIter = csDescs.iterator();
while (csDescIter.hasNext())
{
// retrieve the CommandSet for this descriptor.
ResourceContainerDescriptor tempRCD = (ResourceContainerDescriptor)csDescIter.next();
System.out.println(tempRCD.toString());
containerKey = tempRCD.getKey();
System.out.println(containerKey.toString());
ResourceContentDescriptor csDesc = tempRCD.getContentDescriptor();
if(csDesc!=null)
csColl.add((CommandSet) rMgr.getResource(csDesc));
}
}
} catch (Exception e)
{
e.printStackTrace();
}
}

没人使用这个东西吗？

内存溢出，你把内存多分配一些，并且读入内存的操作时，最好分批次读入。
