Hi all,
I'd like to be able to test how my application is behaving in the case
of some Capabilities are not enabled.
For example, what happens when Capability.DATASTORE_WRITE has a status
of DISABLED.
I had another look at the testing jar and its various classes, but I
didn't find a way to see

Thanks guys! Think I'll just concatenate parent and child ID for
display purposes and keep the rest as it is.

You can use DatastoreService.allocateIds() to get a range of unique
keys that you can then assign to the children.
I have two classes. The first class contains a reference to the
second. One service request might generate several such pairs. So I
figured that I can batch store them at the end of the service request.
To do that I need to generate ID-s for all the second classes. I
thought that allocateIds was

Use a GREATER_THAN_OR_EQUAL and a LESS_THAN filter to match a prefix -
thats the best you can do for a single stored term. You will need to
break the term up into multiple n-grams if you want to query for a
partial match within a term.

Have you tried the GAE/J persistence blog at:

If the client access server with HTTP, GAE is definitely OK.
But in my experience, Telnet is a better protocol for Mud/BBS.
And I think GAE do not support socket function.
If GAE support WebSocket, it will be a good way to approach that...

There is no way to write a JDO object with the low-level API. You need to
convert it into an Entity and save the Entity. Can you post any code?

Hi,
I have an entity called Node with attributes and the setters and getters for
them:
private int source;
private int graphId;
private SetInteger adjacentNodes;
In my servlet I have the following query:
Query query1= em.createQuery(SELECT x FROM pojos.Node x WHERE
graphId=:graph1Id);
Just define entity properties with indexed=False, e.g.
class Authorization(db.Model):
domain = db.StringProperty(required=True)
code = db.StringProperty(required=True, indexed=False) #
update = db.DateTimeProperty(required=True, auto_now_add=True)
and then bulkload

This isn't the full stack trace so it's difficult to be sure, but do
you store AbstractEngineResponses in an HTTP session? If so, it seems
that the class is no longer compatible with the version stored in your
session.
If so, try clearing your cookies. This will create a new session for you.
I'm using JPA, and I'm having a really tough time getting around this
problem. It seems that when I try to refer to an object by way of a
@ManyToOne, somehow DataNucleus wants to assume some kind of ownership
and throws an exception.
I have three kinds of objects: Person, Book, Rating.
This test worked for me
Query query = pm.newQuery(Employee.class);
query.setFilter(lastName.startsWith(lastNameParam));
query.setOrdering(lastName, firstName, hireDate desc);
query.declareParameters(String lastNameParam);
ListEmployee results = (ListEmployee) query.execute(lastname);

Hi,
I have encountered similar error using JDO long time back. I firmly believe
that if you use @ManyToOne or something it means a relationship amongst
them.
Though I don't remember exactly what I did ,Coupleof observations

Hi Hari,
I don't follow what you're saying in #1 below.
#2 - This is just the way I have always modeled classes using JPA. In a
relational database, the @ManyToOne would cause the key of the owning
entity to be stored in the row. In this case, the Rating table would
have a column to hold
On point #1, there is a way in JdO to say which attributes forms a relation
or forms a join between two entities. It need not be the primarykey always.
Also I don't think having more than 1 @ManyToOne relation should be a
problem. I might need to look at my app code in the evening to see how did
Hi, I used it long time ago, but not in appengine.
You need to import the database and tweak a bit the java api.
But it should work ok
