Use a relative path, not an absolute path. So remove the forward slash prefix, to just FileInputStream(test.xml).

[appengine-java] Re: Any single entity or entity group can only be updated about five times a second.
Hi Tim, Ithink you ran into the same problem as me. You can see in my post (http://groups.google.com/group/google-appengine-java/browse_thread/ thread/a0be8114353d9798/c3b9e94f1942d661?lnk=gstq=entity+updated +twice#c3b9e94f1942d661) an example where I just call make persistence once on an entity, but JDO seems to consider that it is updated twice. It seems that there is a kind of problem when you create a hierarchy of objects when the parents are detached (it works perfect is everything is created at once). One of the way to solve that problem for me was to set datanucleus.attachPolicy to attach-dirty (which is the default value) instead of attach-all. I think high level persistence frameworks are still not mature in Appengine. But if you want to be able to persist entities without modifying any of their field (which was my case as I was trying to save entities in memory and roll them back by hand if a set of commit operation failed), then you are stuck... Hope that helps. On 6 déc, 11:00, Tim Cooper tco...@gmail.com wrote: Thanks Peter for your reply. In fact, after doing some experimentation, I'm able to answer most of my own questions, at least unless a Google engineer corrects my answers: * What is an update exactly?

I got my request running extremely quickly, (as quickly as I'd ever expect) by using pm.makePersistentAll(). I passed in a collection: ArrayListObject. I used an ArrayListObject in order that I can persist child objects if different types, and also even the head object, in a single call. * If I don't use transactions, does this 1-10 updates per second limitation go away? tim No. The critical difference is the use of pm.makePersistentAll ().

[appengine-java] Re: JDO bug (entity groups and double update)
Just a short answer to say that I found a similar issue (http://
code.google.com/p/datanucleus-appengine/issues/detail?id=67) about
entities that does not work with unidirectional one to many
relationship after being detached. However converting all my model to
bidirectional relationships does not solve my problem (only setting
the child keys by hand which is not that great...).
On 5 déc, 19:34, Ratamovic ratamo...@gmail.com wrote:
Hi everybody,
My model contains a Class A ---Bidi one to many--- B ---one to

I wrote 3 unit tests with appengine 1.2.8 and JDO on eclipse 3.5 which
generate an error.
It looks like a bug in JDO to me but I may be wrong:
1- org.springframework.orm.jdo.JdoSystemException: can't update the

However (see the code below), when I change the member variable
expList of class A then it works. An other way is not to call setEmail
of class A (but if I set the firstName which is also a String then it
works)...
This look like a JDO bug or bug to me.
2- com.testgae.xp.server.dao.DaoException:

}
Here I don't understand because A and C should be in the same group.
There are only owned relationship between them. If I create the
hierarchy A-B-C-D all at once it works. But not if I do A-B and
then -C-D like in my second test. Is it a bug in my code or a JDO
bug again?
If I set manually the key of class C (as a child of B) then that
works... Another way to make it works is to change the Set of C to a
List of C in class B.
Isn't it a bug in JDO or something?
3- my childs are never loaded. But if I used theupdatedobject
returned by my DAO instead of loading it from the datastore, then that
works. All my requests return null. I can't understand why because
this was working in appengine 1.2.1.
This is likely something about my code is missing or wrong but I can't
see what.

[appengine-java] Re: JDO bug (entity groups and double update)
Thx for your answer. To clarify these points:
1- The transaction is really a JDO/datastore exception encapsulated by
Spring (as I am using the transactional components of Spring). To be
sure, I tried to execute these tests with manual transactions instead
of not Spring and the result was the same (except that it was not a
Spring exception but the message was the same).
3- You're right my comment is a bit imprecise:
Sorry for the confusions or imprecisions :D. My problem is when I load
an object A which contains a list of B. Although one B was added to A,
it does not get loaded when I load A. But it is in the object returned
by makePersistent within my DAO:
public final void testBug3() throws DaoException {
...
// Here I add B to A
a.addB(b);
//
A a2 = _aDao.update(a);
a = _aDao.loadByKey(a.getKey());
...
// Returns an empty list if I use object a but contains one
element if I use a2 instead.
a.getBList()
}
In my DAO (which is not in my previous post, only in my Zip), I set
the fetchDepth to 3 and used defaultFetchGroup to force loading (I
also tried -1). But usually errors returned by JDO in that case are of
the kind object not detached and the list still contain the correct
number of elements even if they are not loaded.
However I have just realized that I am getting the persistence manager
through the PersistenceManagerFactoryUtils of Spring several times
(once in getPersistenceManager() and once in getFetchPlan() in my
DAO). Although I think it gives the persistence manager for the
current thread, I should make it sure. I'll give it a try this
evening.
Here is an extract of my DAO:
public class ADao implements IADao
{
...
public final PersistenceManager getPersistenceManager() {
return PersistenceManagerFactoryUtils.getPersistenceManager
(_persistenceManagerFactory, true);
}
public final FetchPlan getFetchPlan() {
return PersistenceManagerFactoryUtils.getPersistenceManager
(_persistenceManagerFactory, true).getFetchPlan();
}
...
public final A loadByKey(Key pKey) throws DaoException {
PersistenceManager lPersistenceManager = getPersistenceManager
();
try {
getFetchPlan().setMaxFetchDepth(3);
A lAggregate = lPersistenceManager.getObjectById(A.class,
pKey);
return lPersistenceManager.detachCopy(lAggregate);
}
catch (JDOObjectNotFoundException eJDOObjectNotFoundException)
{
return null;
}
catch (Exception eException)
{
throw new DaoException(eException);
}
}

Propagation.REQUIRES_NEW)
public final A update(A pA) throws DaoException {
PersistenceManager lPersistenceManager = getPersistenceManager

try {
A lUpdatedAggregate = lPersistenceManager.makePersistent

return lUpdatedAggregate;
}
catch (Exception eException)
{
throw new DaoException(eException);
}
}

lQuery.setFilter(_email == emailParam);
lQuery.declareParameters(String emailParam);
lQuery.setUnique(true);

return executeUniqueQuery(lQuery, email);
}

Re: [appengine-java] Re: oid is not instanceof javax.jdo.identity.ObjectIdentity
I don't see a class that is owned by more than one entity in your latest
example. What exactly should I be looking at?
Your understanding of the BigTable layout is correct, but you're bumping
into a limitation of how we've mapped JDO on to that layout. The low-level
api knows nothing about your data model and will allow you to create
whatever parent/child relationships you want. However, the low-level api
also knows nothing about ownership and dependent data. We need JDO to
enforce these expectations, and in order to enforce these expectations
transactionally we need to put owned entities in the same entity group as
their parents. We also assume that each child object only has one type of
parent, and that restriction is causing problems for you.
Why do we have that last restriction? To be honest, I never considered not
having it because in a relational database, if you're modeling ownership
with foreign keys, the foreign key that points to your owner typically
points to a record in a specific table - the schema dictates the type of the
parent. With JDO on top of the datastore, however, it does seem like we can
take advantage of the underlying flexibility. So long as the relationship
isn't bidirectional (no parent pointer on the child), you should be able to
have an object be the child of any number of different parents. Very
interesting, thanks for pushing! I'll file an issue for this. It might be
easy or it might be hard, I'm not sure.
So what can you do right now? Unfortunately you're stuck with unowned
relationships. Note, however, that just because you've implemented
something as an unowned relationship doesn't mean you need to expose it that
way in your object model. The datastore doesn't do joins, so something like
this:
class Person {
Key addressKey;
transient Address address;
synchronized Address getAddress() {
if (address == null) {
address = loadAddress();
}
return address;
}
is not actually any less efficient than using an owned relationship. Yes,
you have to write more code and it's up to you to ensure that the Address
gets deleted when the Person gets deleted, but in terms of the code you need
to write to interact with the model objects it shouldn't be that different.

Thanks for filing that Max.
I'm kind of interested in your findings because there is another place
where I'm doing about the same thing (i.e. making a RatePlan instance
a direct child of an Entity other than Activity) and it works fine in
that case most of the time. Sometimes it gives me the oid is not an
instance of javax.jdo.identity.ObjectIdentity exception.
here's the model:
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class ActivityReservation extends BaseBean
{
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
private Key id;
@Embedded(
members={
@Persistent(name=key,
column=activityKey),
@Persistent(name=name, column=name),
@Persistent(name=pricingModel,
column=pricingModel)
}
)
@Persistent(defaultFetchGroup=true)
private ActivityFK activity;
@Embedded
@Persistent(defaultFetchGroup=true)
private ActivityLaunchFK launch;
@Persistent
private RatePlan ratePlan;
@Persistent
private BigDecimal totalCost;
@Persistent
private ListGuest guests = new ArrayListGuest();
}
and
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class Reservation extends BaseBean
{
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private SetActivityReservation activityReservations = new
HashSetActivityReservation();
@Persistent
private Date createdOn;
@Persistent
private String contactName;
@Persistent
private BigDecimal totalCost;
@Persistent
private BigDecimal totalPaid;
@Persistent
private BigDecimal balanceDue;
}
I'd really like to avoid using a Key instance rather than a RatePlan
instance because I want to ensure that the RatePlan linked to a
BundledActivity or an ActivityReservation is not used anywhere else in
the system. If I allow a Key instance there, someone may be tempted
to put the Key of an un-owned RatePlan which can be edited out of
context. So, I need to make sure I understand this limitation: if
class A has an instance (or instances) of class B in your data model,
then class C is not allowed to have an instance (or instances) of
class B? I don't remember reading that in any of the docs, but
perhaps I simply missed it. That's kind of a big deal for me. I'm

[appengine-java] TransformerFactory.newInstance() not working in App Engine SDK 1.2.8
Dear All,
I just migrated my code to App Engine SDK 1.2.8 and GWT SDK 2.0.0.
I have a method that converts an XML Document object into a string:
public static String getStringFromDocument(Document doc) throws
TransformerException {
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
return writer.toString();
}
Unfortunately I now get this error in the SDK:
javax.xml.transform.TransformerFactoryConfigurationError: Provider
org.apache.xalan.processor.TransformerFactoryImpl not found
at javax.xml.transform.TransformerFactory.newInstance
(TransformerFactory.java:108)
I do not get this error when I upload my app. Any idea what is going
on?
Best wishes,
Dan

Re: [appengine-java] Re: oid is not instanceof javax.jdo.identity.ObjectIdentity
On the ActivityReservation model object, there is an instance of
RatePlan (which is also a child object of Activity).
So, here's a thought, I will try it out later, but I thought I'd ask
right now about it:
how about having subclasses of RatePlan that live on different parent
objects? since RatePlan does not have a pointer up to it's parent, I
think this could work, but I don't know about the underlying
app-engine JDO implementation issues that might cause. I'm thinking
something like ActivityRatePlan, BundledRatePlan etc. that don't
really add any api/field functionality, but do make it so that only a
Bundle is the parent of a BundledRatePlan, and only Activity is the
parent of ActivityRatePlan etc. etc. do you think that would cause
any issues?
I'd love it if you could look into allowing more than one parent
object type for a given child object type. If it's not too much
trouble, it'd really help me out.
in your Person example above, the loadAddress() method probably uses
either a PersistenceManager or some generic wrapper for it? If that's
the case, I'm wondering how that scales. I've kind of viewed one of
the main advantages of using JDO/JPA is that the persistence framework
deals with that lazy loading/orphan deletion for you.
I could also make some kind of embedded field that is embedded only, I
think I've had luck with putting those kinds of objects on multiple
parent object without an issue. That may work for me.
thanks again Max, you've been a big help.

Thanks for filing that Max.
I'm kind of interested in your findings because there is another place
where I'm doing about the same thing (i.e. making a RatePlan instance
a direct child of an Entity other than Activity) and it works fine in
that case most of the time. Sometimes it gives me the oid is not an
instance of javax.jdo.identity.ObjectIdentity exception.
here's the model:
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class ActivityReservation extends BaseBean
{
�...@primarykey
�...@persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
private Key id;
�...@embedded(
members={
�...@persistent(name=key,
column=activityKey),
�...@persistent(name=name, column=name),
�...@persistent(name=pricingModel,
column=pricingModel)
}
)
�...@persistent(defaultFetchGroup=true)

Re: [appengine-java] Inherit one-to-many relationship
Could you please post all the model objects that are involved in the
example? Looks like SpeciesStats is missing. Also, it would be great if
you could post the code that shows how you populate the Community object
before persisting.
Thanks,
Max

Hi,
I have a problem when I try to inherit a one-to-many relation ship

The following model works fine :

@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public abstract class BaseEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
public Key getKey() {

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Community extends BaseEntity {

@Element(dependent = true)
private ListSpeciesStats stats = new ArrayListSpeciesStats();
public ListSpeciesStats getStats() {
return stats;
}
@Persistent(dependent = true)
TackleBox tackleBox;
public TackleBox getTackleBox() {
return tackleBox;
}
public void setTackleBox(TackleBox tackleBox) {
this.tackleBox = tackleBox;
}
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class TackleBox extends BaseEntity {
/* some other properties that eventually extend BaseEntity and so on
*/
}
But if I move private ListSpeciesStats stats from Community to
BaseEntity, I get a runtime exception when trying to read a Community
entity :

[appengine-java] Re: Class XXX has multiple relationship fields of type YYYY
Thanks Max! Just updated to 1.2.8 and ran into this problem. The workaround looks good, though I think you specified the boolean value wrong if you want to disable this error. Should be: property name=datanucleus.appengine.multipleRelationsOfSameTypeAreErrors value=false/ In my case, the app builds fine with no Enhancer errors or warnings. However, when I run my app, I'm get the following error when I try to load entities that extend an abstract base class: javax.persistence.PersistenceException: Persistent class XXX does not seem to have been enhanced. XXX is an abstract class similar to your B class above. Any ideas?

Re: [appengine-java] Re: XMPP Message not being received
Hi Googlers and GAE users,
I changed code little bit, there was one problem.And then i tried sedning a
message every 2 seconds and it went fine.
I think after this fix i will be able to get a speed of 80 messages/second,
but still far away from 3000/second.
i removed this line
* Chat chat = connection.getChatManager().createChat(
ap...@appspot.com, messgageHandler);
*from function sendToGae and then i could send messages faster. Now Chat
chat is my class variable and get created once in constructor . And after 1
message per 2 seconds i got curious and just ran the loop to send many
messages with out any delay and after sending 92 messages continuosly i got
Constraint response.It didnt say much about what constraint but i could send
90 messages in a row without delay.*
*
public void sendToGae(String message) throws XMPPException, MessageException
{
* Chat chat = connection.getChatManager().createChat(
ap...@appspot.com, messgageHandler);*//this line i removed
//messageHandler will receive the message back from server, if i receive
the

Hi Ikai,
Yes you are right you might have got 10 messages/minute. As i said i also
got 12 messages/min once( 1 messages every 5 seconds), but this not what i
was expecting. Iwas expecting around 3000 messages/min. I had to send around
5 messages and it completed yesterday. And first time i started sending
messages on 24 Nov. so total 7 nights.
But i think for 5 messages i should have spent around 5/3000 = 17
minutes provided i stil have quota for the day. Lets says things are bit
slower with GAE, so i can expect 1 hours. I am sure there is something
missing somewhere. Does gtalk.google.com(XMPP server) has any limitation?.
or any other problem.
Can you please try to send like 1000 mesasges in a minute and let us know
the result.
And in my previous mail i forgot to add the response.
The response i was getting for those messages was Service-unavailable .

Re: [appengine-java] Copy production datastore to local_db.bin?
Regarding your question about connecting development code to the hosted datastore: there's a tool in Python for connecting to the remote datastore: http://code.google.com/appengine/articles/remote_api.html The article has examples on putting together an interactive console, or otherwise working with entities programmatically using Python. A single datastore is not specific to Python or Java (some gotchas apply, such as if you use serialized fields), so you can deploy a Python version of the application that only implements remote_api. The concept is similar to the cookbook recipe for using the Python bulk loader for a Java application: http://appengine-cookbook.appspot.com/recipe/using-the-python-bulk-exporter-tool-with-a-java-application/ On Fri, Dec 4, 2009 at 6:05 PM, Hank Beasley hankbeasleym...@gmail.comwrote: Is it possible?
