Re: [appengine-java] Re: hijacked domain
Yes, I disabled the Google Sites App and removed my App Engine App. After about an hour I added the App Engine App again and mapped it to my domain. The App Engine app works on my domain just fine now.

Hi Don, thanx for your quick reply. I am pretty sure I am not catching DeadlineExceededException anywhere in the code (but I'll check again...).

[appengine-java] So I found out I can't simulate "post" in a cron job and pass parameters after "?" in URL
I know it kinda looks ugly since I had to add a doGet method to my servlet to call doPost with the request and response objects... but it was going to get the job done! Or so I thought... I'm getting a "com.google.apphosting.utils.config.AppEngineConfigException: XML error validating" exception when GAE tries to match my cron.xml to the xsd file. The url looks something like this "/doCall? user=test&rank=1". Am I missing something or there's no way to set-up a "real" cron job with command-line arguments and that kind of stuff? We can just do a dumb get to a servlet? Like I said, I may be missing something... -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Scope of datastores -- accessible across multiple GAE applications?
What is the defined scope of a datastore as used by your JDO/JPA code in a Java application deployed on GAE? Can you only insert/retrieve data for a pre-defined datastore associated with your running app, or can you connect to another application's datastore and insert/retrieve data from that data store as well? Example: Consider a very large data-mining application written and deployed on GAE as separate applications: 1. Harvester -- application scrubs the web all day long looking for information and inserting it into it's data store. Lots of the new experiemntal Task API used here. 2. Website -- website used by customers to search the compiled data, create accounts, and do other compelling things with it -- like rank it. This would be reading/updating data from App #1's datastore. 3. Admin -- website used by admins to manually modify the information in the system -- again, manipulating the data from App #1's datastore. Is this possible? Or would I just have to model this entire application as a single huge GAE application in order to allow all those pieces to share access to the datastore that the Harvester creates and maintains? Thanks for the assist guys. Best, Riyad -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] JDO Mapping issue : A parent cannot be established or changed once an object has been persisted.
I have three classes
Album{
Artist albumArtist;
@Persistent(mappedBy = "parent")
@Element(dependent = "true")
List songs;
}
Song{
Artist singer;
Album parent;
}
Artist{
String name;
}
If I use the Artist instance I create for Album for Song(singer) - I
get an error
javax.jdo.JDOFatalUserException: Detected attempt to establish Album
(1) as the parent of Album(1)/Song(2)/Artist(3) but the entity
identified by Album(1)/Song(2)/Artist(3) is already a child of Album
(1)/Song(2). A parent cannot be established or changed once an object
has been persisted.
CODE - THIS throws the above error
Artist artist = new Artist("First", "LastN", "First Last");
Album album = new Album("Ahat and album", artist, 1978);
Song song = new Song("Som song", album, artist);
album.addSong(song);
dao.makePersistantAndCommit(album);
CODE: This works
Artist artist = new Artist("First", "LastN", "First Last");
Artist artist2 = new Artist("Second", "LastN", "Second Last");
Album album = new Album("Ahat and album", artist, 1978);
Song song = new Song("Som song", album, artist2);
album.addSong(song);
dao.makePersistantAndCommit(album);
>From my app requirements standpoint - I can have an Artist who is the
albumArtist and who is also the singer. And hence I have a need to use
the Artist instance.

Re: [appengine-java] Handling HardDeadlineExceededError
You cannot catch HardDeadlineExceededError. DeadlineExceededException should be thrown first. Perhaps some code you are using is silently catching and ignoring it?

[appengine-java] Handling HardDeadlineExceededError
Hi, I am trying to build some mechanism for handling HardDeadlineExceededError (and other timeouts as well). I wish to catch this Error and wrap up my work so I can send my own response instead of the default error (500) message that GAE produces. Here's the problem. I cant catch this Error for some reason.I've made sure my catch clause is in the right place (from the error provided stack trace). I even catch a Throwable to make sure I don't miss the Error. Sadly I don't reach the catch clause. Has anyone had some experience with this? Do you have some other innovative ideas on how to handle such timeouts ? B.T.W I would have expected that a DeadlineExceededException would be thrown instead , dont you?

[appengine-java] Re: What Java MVC framework do you use on AppEngine?
I tried Django the other day and find that its feature set needs some polishing (especially in the forms, or newforms if you have been a long user of Django) The situation for ORM mappings is kind of the same for both systems. One of the reason that django could be much faster because of the code loading (is it lazy loading?) which we know are very different for Python and JRE.

[appengine-java] Re: JDO Query for properties with null values
I am new GAE and I need some help. Is it possible to query for
entities with a property value null using GAE JDO query?
I want something like
"Get me all the Files that don't have a parent"
In regular relational DBs, it can be queried some thing like this:
"select * from File where parentKey is null"
I have a class something like this:
public class File {
@Persistent
@PrimaryKey
private Key id;
@Persistent
String name;
@Persistent
private Key parentKey;
}
When I am querying for Files that have null parentKey, query returns
all Files including those with non-null parentKey value. Is this
possible to do with GAE?
Thanks!

[appengine-java] Re: List of embedded class objects in default fetch group
Hi.
I'm using 1.3.0, but further investigations shows that this might not
be related to lazy loading after all.
I don't seem to be able to save/retrieve lists of embedded objects at
all...
I wrote some test examples to show my problem. I probably do something
wrong here, but I really can't figure out what...
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Test {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String iEncodedKey;
@Persistent(defaultFetchGroup = "true")
private List innerTests;
@PersistenceCapable
@EmbeddedOnly
public static class InnerTest{
@Persistent
private String whatever;
public InnerTest(){
whatever = "whatever";
}
}
public Test(){ }
public void addSomeInnerTests(){
innerTests = new ArrayList();
for(int i = 0; i < 5; ++i)
innerTests.add(new InnerTest());
}
public List getInnerTests(){
return innerTests;
}
}
and then I use the following testcode to save and retrieve the objects
// For saving
Test test = new Test();
test.addSomeInnerTests();
Test saved = pm.makePersistent(test);
System.out.println("persisted Test innerTests size = " +
saved.getInnerTests().size());
System.out.println("Saved Test key = " + saved.getKey());
// For retrieving
Query query = pm.newQuery(Test.class);
List list = (List)query.execute();
System.out.println("Tests = " + list.size());
for(Test test : list){
System.out.println("Retrieved Test key = " + test.getKey());
List innerTests = test.getInnerTests();
System.out.println("innerTests size = " + innerTests.size());
}
and this provides the following output
persisted Test innerTests size = 5
Saved Test key = agtib2xsdHJvbGxlbnIMCxIEVGVzdBjbsAEM
Tests = 1
Retrieved Test key = agtib2xsdHJvbGxlbnIMCxIEVGVzdBjbsAEM
innerTests size = 0
So, why is the List in the retrieved Test empty? I have tried
retrieving an object directly as well, but this naturally leads to an
IndexOutOfBounds.
In my real code, all the other variables are saved and retrieved
properly. I have Lists of Strings and such as well, and they work just
fine, so its definitely related to children/embedded objects.
Any help is appreciated.
Thanks / Andreas
