...Please post your question on the Google Group for GAE Java (the
link is in the App Engine Links section on the right) along with your
model objects and the code you're using to query for the child
objects
I have been attempting to do an owned one-to-many and have followed
the example here. I have also tried for more than 10 hours
experimenting with sight variations (looking at other examples) and
using the debugger. I save the parent with a long list of children
with no erros. No matter what I do it when I query and get the parent,
the child list comes back empty. My datastore now has 10s of parent
records.
One difference is that my fields are public. Is that the problem?
I don't think it could be.
Another difference is that when I use:
public List chapters = new ArrayList();
When I try not using generics on the ArrayList I get the following
runtime error:

I don't get the ClassNotPersistenceCapableException runtime error if I
declare the list as:
public Listlang;Chapterrang; chapters = new ArrayList〈Chapter〉
();
However, I am unable to query and get back any of the items that were
in the list.
I have also tried
@Persistent (defaultFetchGroup = true)
private Book theBook;
in the child, and that gets this warning:
Jan 12, 2010 8:06:34 PM
org.datanucleus.store.appengine.MetaDataValidator warn
WARNING: Meta-data warning for lt.server.Lyric.theBook: The
datastore does not support joins and therefore cannot honor requests
to place child objects in the default fetch group. The field will be
fetched lazily on first access. You can modify this warning by setting
the datanucleus.appengine.ignorableMetaDataBehavior property in your
config. A value of NONE will silence the warning. A value of ERROR
will turn the warning into an exception.
To clarify the above, I think I have tried everything except private
fields and a non-generic ArrayList. I have never been able to get the
child records back, although I get the parent.
(I have edited the above to change from Song to Book and Lyric to
Chapter to agree with your example)
Here is my query code:
public lt.client.Song getSong(String input) {

try {
String query = select from + Song.class.getName()

[appengine-java] Re: problem in XMPP sendMessage()
I removed .withFromJid(new JID(recipientJid[0].getId()) )
but I am still facing problem.
The servlet works correctly for first two messages. But problem starts
when servlet receives third message.
I find this strange. Initially it works fine, but gives problem from
third message.
Regards
Sahil Mahajan

I am not sure, but i think you dont need to(should not) set fromJid, as
message will be sent from your application JID.
I am running following code and its working .
JID jid = new JID(responseJid);
Message msg = new MessageBuilder()
.withRecipientJids(jid)
.withBody(msgBody)
.build();
boolean messageSent = false;
XMPPService xmpp = XMPPServiceFactory.getXMPPService();
if (xmpp.getPresence(jid).isAvailable()) {
SendResponse status = xmpp.sendMessage(msg);
messageSent = (status.getStatusMap().get(jid) ==

[appengine-java] XMPP and JID
Hello I am using XMPP API. It looks that JID of a google account user does not remain constant. If a user is using gmail, then his JID is mai...@gmail.com/gmail.SOME_NO and when he is using gtalk JID is mai...@gmail.com/talk.SOME_DIFF_NO. I need to have something (for example mail id) which remains constant every time a user uses my website. I didn't find any function to extract constant part of JID. I tried using Users Service of Google App engine by including import com.google.appengine.api.users.User; import com.google.appengine.api.users.UserService; import com.google.appengine.api.users.UserServiceFactory;*** *but user remains null. Is their any way to get constant part from all Types of JID's. * *Regards Sahil* * -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

But it looks that my clients are interacting with different servers and changes are not reflected. What can I do to make this possible?
