[appengine-java] Re: Per-minute quota
Thanks for the answer, But during 1 minute I'm able to run out of several quotes so this approach does not work for me. It is too complicated and lime consuming.

[appengine-java] Per-minute quota
Hi! Sometimes I can see this message: This Google App Engine application is temporarily over its serving quota. Please try again later. Is there a way to find out: which exact per-minute quota was exceeded? Thanks, Anton -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: One-to-many relationships and saving
Dear Max,
I read the doc, but it seems to me that it describes 1-N
relationships, but there is a talk about 0-N relationships.
I have the same trouble and here is an example:
class BugReport {
Key id;
List commentList;
}
class Comment {
Key id;
}
So in this case I need 0-N relationship because when BugReport is
submitted, there are no comments yet.
But if I try to get list of BugReports or save second BugReort I'v got
an exception:
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found.

Is there a walk-around which can allow me to use 0-N relationships?

[appengine-java] Server error 500
Hi!
My application became completely broken and now I can not eve backup
data!!! Datastore does not work any longer, all the data is lost.
Here is page:
http://herewetest.appspot.com/jdo.jsp
Here is source code:
<%
Query q = PMF.getInstance().newQuery(Website.class);
List o = (List)q.execute();
for (Website w : o){
%> . <%
PMF.getInstance().deletePersistent(w);
}
%>

[appengine-java] Re: JDOQL - query syntax documentation
Hi!
Thank you. Now I understand why contains(...) will not solve my
problem. Actually we can see that it is only possible to search
through sting fields using startsWith(...). Function matches(...) does
the same.
Basically it means that if I have text fields like "221B Baker Street,
London, UK" and I want to find everybody from London than I have to
split the address to separate substrings, save them to datastore and
use query like this to find English mans from London:
substringIndex.startsWith("London")
Can anybody tell me please, if there is more smart way to do this?
Thanks,
Anton Ananich
