[appengine-java] Why is guestbook-example-fts (full text search) example working but mine is not?
Hi, I'm really confused about the AppEngine database index limits. My project is using 15 tokens to index some content. I'm using the index then to self-join it up to 3 times. Then my index looks like this: isOnline ▲ , searchIndex ▲ , searchIndex ▲ , searchIndex ▲ , normalizedName ▲ isOnline = boolean searchIndex = list (max 15 items) normalizedName = string Now as soon I add another searchIndex or another property to the indexes I get an error when AppEngine is trying to build the indexes. -- BUT -- Then again I'm looking at the http://code.google.com/p/guestbook-example-appengine-full-text-search/ example which was mentioned by Googles AppEngine Team. This project is using 200 tokens to index! and self-joining it up to 5 times! How is that possible and what I am doing wrong? I need at least one more property to be added to the index.

[appengine-java] Object Manager has been closed on 2 synchronous requests
Hi,
I'm getting an JDO/Nucleus exception when running 2 synchronous
requests on different ids of an object:
org.datanucleus.exceptions.NucleusUserException: Object Manager has
been closed
---
This is how my getById looks like:
PersistenceManager pm = getPM();
Stream stream = null;
try {
Stream tmp = pm.getObjectById(Stream.class, id);
stream = pm.detachCopy(tmp);
} finally {
pm.close(); // here the exception occurs
}
return stream;
---
It works fine on single request, but fails on 2 or more.
anyone know how to get around this?
Thanks

[appengine-java] Re: Object Manager has been closed on 2 synchronous requests
Hmm, does it really matter even when using detached objects?
And aren't the persistence managers created individually on each
request?
I didn't know they are shared over many requests?
What's the best way to update about 20 objects synchronously using 20
asynch urlfetches?
It needs to be urlfetches, because the 20 objects are getting updates
from an urlfetch again.
Simple model:
- call 20 urls with individual ids
- each url gets an objects and gets its updates from another url
Any good solution for that?
Thanks

hi,
you should only close the persistence manager when your done.
This error occurs because you try to close it a second time.
Once you do the pm.close() all the data will be updated

[appengine-java] Re: Database cursor for back cursor?
But isn't it getting slower and slower on higher pages, since it fetches ALL data (according to docs) and discards the offset value? So Range(0,10) is faster than Range(1,10) ? Anyone did some performance tests? Regards On Apr 3, 7:49 am, John Patterson jdpatter...@gmail.com wrote: Probably you should set an offset and limit instead for your paging. I believe cursors are really intended for processing a lot of data off- line. Remember there is no longer a 1000 result limit on fetches.
