I'm finding the JDO cursor usage documentation a bit confusing.
According to the docs at

To get the initial page of results:
query.setRange(0, 20); // which makes sense
Then to get the second page of resul

I'm trying to test sending email using Java from GAE SDK 1.3 while in
development mode using the Eclipse Plugin. I'm using Eclipse Build id:
20090920-1017 and Java OpenJDK 1.6. Is this possible, or can I only
send email when my app is actually deployed? I read the docs and I am
aware that it says i
I'm trying to persist a simple class relationship using JDO. My code
is listed below and here's a brief overview of what I'm trying to do:
I have 3 classes:
Person, Customer (extends Person), and Address (referenced from
Person). If I create a Person instance and an Address instance and
call setA

tried the base class as abstract and concrete, and tried the keys as
type Key and as encoded String. No luck.
Thanks very much for any help.

use this type of inheritance in my app, I will post another message to
let people know how it turned out.
In the mean time, I'm hoping that we'll see an update to fix this

I have an object model with a Person class that references several role
classes, e.g. Customer, Partner, Administrator.
Since GAE does not support polymorphism, I am trying to implement the

each of the role classes. It loo
I'm using JDO with app engine. I have an class, Person, that contains two
collections:
private ArrayList parentKeys;
private ArrayList roleTypes; // RoleType is an enum, defined as a

I am using transactions. When I add a RoleType value to roleTypes prior to
calling
