I've just started getting the following error on my server. This query
had been working fine for months, and I haven't changed the indexes
lately. Are there some indexes that just buckle under heavy load or
larger data sets? This particular table contains only 242,604 entries.

One of my tasks encountered a failure and wasn't retried. I think it's
because the servlet returned a 200 response, but I don't know why it
did since the exception bubbled all the way up to the base servlet. Do
we need to explicitly return a 5xx error code in exception cases for
retries to work?

I'm getting some very confusing behavior regarding indexes in my app.
Maybe someone can help me figure out what's going on.

all indexes for GameDataV1 were g

a more descriptive error message would help here. I think the real

I've been seeing a handful of these each day on my app. These are very

remedy?

I've got a Game object that includes two PlayerGameState objects. Both
are persistence-capable. My query fetches all PlayerGameState objects
for a particular user, then I get the associated game and other
player. The initial fetch is always fast, and the entire operation is

I have a data file I need to access on the server. If I include it in
my source path on the client I can load it via
ClassLoader.getSystemResourceAsStream. But this breaks on the server
(I'm not sure if the eclipse plugin is even deploying it). What's the
best way to do this? I don't want to incur

I have a Room class containing a list of Presence classes. Here are
the annotations.
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Room {
private final static Logger LOG =
Logger.getLogger(Room.class.getName());
@PrimaryKey
@Persistent(valueStrategy = IdGenerator
I have a servlet that returns a JSON string. For some reason it works
fine when I dispatch to a JSP, but sometimes fails when I write
directly to the response.
this works:
req.setAttribute("json", json.toJSONString());
req.getRequestDispatcher("json.jsp").forward(req, resp);
If I annotate a dependent 1:many relationship with @Order(mappedBy =
"foo"), I get a NPE when I try to remove something from the list. When
I remove the annotation everything works fine. Is this a known
limitation? If not I can post a stack trace and more details.

Hi All,
I want to use the low level datastore, I looked at the documentation
and it looks ... complex.
http://code.google.com/intl/zh-HK/appengine/docs/java/javadoc/com/google/appengine/api/datastore/package-summary.html
Basically, I have a client program which needs to create tables and
their en
cleus/test/
SequenceExamplesJDO.java), it seems if I specify a named sequence and
set SequenceStrategy.CONTIGUOUS (NONCONTIGUOUS might work too, I'm
guessing !TRANSACTIONAL is the key) that I get a monotonically
increasing sequence. Does that seem right?
Thanks for the input,
Philip

I'm using IdGeneratorStrategy.SEQUENCE for the primary key of a table,
but it appears AppEngine bounces between 2 different sequence
generators as I create new entries. IDs are unique, but not
monotonically increasing. It's possible I've coded something wrong,
but I'm oretty sure this is a bug.
