Hi,
Using mapper i am trying to allocate id's to the entities which are already
in the name space. And i am using appengine-java-sdk-1.5.0.
But when i run the mapper its throwing the exception. And i could not find
what is the reason and also unable to stop the mapper ? what is this
exception ?
Is their any way to debug and find the reason behind this exception ?

This is the part of mapper code:
.
.
.
.
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
KeyRange range = new KeyRange(p.getParent(), p.getKind(),
p.getKey().getId(), p.getKey().getId());
ds.allocateIdRange(range);
.
.
.
Any help would be greatly appreciated :)
