Hi
I just wanted to confirm that I am using the PersistenceManager in the
correct manner... I have a List of a JDO persisted class retrieved in
my Spring MVC controller as follows:
protected ModelAndView handleRequestInternal(HttpServletRequest req,
HttpServletResponse resp) throws Exception {
Regarding maven-gae-plugin - for now, the best way to adopt your
application is to copy/paste pom parts from one of the example
projects (plain jsp or gwt). It's not trivial, but not impossible.
Also I tried to document every piece of pom.xml there.
However it is true, that this plugin has become

I am afraid I am not able to reproduce the problem.

Can that be clarified a bit? GAE concurrent requests are capped below 10

realistic compared to non-trivial 3-tier JEE clusters where an installation

The string you should put in the ORM properties page is src/, could
you try that instead of /src?

Datastore cursors is something we hoped to support in 1.2.8 but it didn't
quite make it in. There are changes in the ORM code to support it but it's
not actually enabled in the datastore back-end. This should be available
early next year.

Hi all,
this is probably already discussed but I am slightly confused over
what is and what is not supported in Google App Engine.
I was looking at Google App Engine's What will play page and it says
that JAXB is supported totally in Google Appengine. But on Apache Wink
Project Wiki, they have
JAXB wasn't working until about December 10th and version 1.2.8. So I
guess the Apache Wink Wiki might not be updated yet.
I personally haven't tried Wink but I can vouch for JAXB support.

I believe the exception you're getting is the result of having multiple
parents for the same type, and unfortunately that bug isn't fixed in this
release. The bugs fixed in this release are:

good point, I kinda got lost in the exceptions I was getting :)
I wound up sorting it out by making an embedded class instead of
having multiple parent classes for a given child class. Although, it
would be nice if a child class could have different parent types.
Thanks for all your help Max.
Sure, sorry it was such a headache for you. When I've got a fix ready I'll
let you know.

Hey ,
why do you want to close the persistance manager here, you are not
saving or updating any entities.
You should use a static PMF class to get the entity manager und you

Hi,
Can we use java enums as @Persistent data fields in the Data
classes? There is no tutorial that talks about java enums being used
in the Data classes.

You can access the local datastore via the web interface when the
app is running.
If the app is running at http://local:8080,
point browser to http://local:8080/_ah/admin/datastore
You will see all your data there... and can edit/delete/clear them.
The datastore is saved locally as a .bin file

different parent types for child objects should work fine as long as you use

JPA _only_ supports list-ordering (the good kind). You can use the @OrderBy
annotation to specify the properties to order by, but even if you leave this
annotation off it will order by the primary key field.

hahaha, no that doesn't sound draconian. I remember reading that the

too deep into it yet (since I'm only doing a proof of concept right
now). I have some questions about it though. For instance, what if I

If you order by anything other than your primary key you'll take a
performance and cpu hit on writes but there won't be a penalty on your
reads. The reason the JDO default is such a problem is that it adds an
implicit property to each child entity containing the position of that
entity in its

A Set will not suffer from this same problem. The datastore has no way of
knowing what the sort function of your SortedSet might be so this will be
treated as an unordered Collection as well, but the sort will happen
in-memory as the collection is populated. If the collection has an explicit
