Intro:
I am an experienced embedded 'C' developer;
I have written a little C++ and C#;
I am new to both Java in general and AppEngine in particular;
I don't know Python at all.
I am trying to use the datastore, following the Book Store example
in the online docs:
GWT RPC is failing when I view my site with my custom domain, which
was successfully attached to my google app. GWT RPC succeeds when I
view my site with the myproject.appspot.com address.
Why? Is the httpxmlrequest pointing to myproject.appspot.com instead
of the the custom domain? Obviously it
It seems that I've used my own Run Configuration where I included a
wrong nucleus-appengine-something.jar in the classpath. When I added
the Jar-File by hand the enhancer didn't work anymore. I created a new

Oh, ok the reason RPC is failing is because I had the subdomain of the
custom domain set to forward to http://myproject.appspot.com on my
domain hosting service provider. I truly believe that would result in
the RPC being cross domain and thus failing. I followed the steps of
adding the subdomain
Hello Sky,
When my application launches, I create a queued task which constructs
my singleton PMF instance asynchronously.
My getPMF() method then uses this instance, and creates it at once
if it is not yet created for some reason.
This way, the creation of my PMF does not cause a delay to app

pm.deletePersistentAll(Collection c) method gets collection as

pm.getExtent(Class class) gets all the images in datastore (as
iterable)
you could use getExtent to get all data, convert it to collection and
use deleteAll to remove everything.
I am curious, does it matter if I call the factory each time I need an
instance of MemcacheService? I am trying to keep the startup time to
minimum so it would be good to know. Currently I create a global
instance on startup which may or may not be used by the request.

Hello,
I have the following index definition in the datastore-indexes.xml:
datastore-index kind=TransactionEntity ancestor=false source=manual

property name=time direction=asc/
Try cleaning and rebuilding the project. I had a similar error in a
GAE + GWT project, and I think that's what solved it for me. But I'm
not sure I'm remembering right, so please report back if that or what
else solves it.

You can call the factory any times it doesn't matter it will return you the

The status shows that your index updates are Queued which would
suggest that they are waiting for other users indexes to be built first.
Note that when you create the index definitions first then add the
data, the indexes are created on-the-fly as each entity is added and

I realize that I always get the same cache. I am just wondering if it
creates an overhead to always call the factory or not.

Jut need to be careful that if you reuse the same instance you don't
depend on the namespace or error handler which are per-instance. Also
worth pointing out that although google devs have mentioned on this
list that it is OK to share MemcacheService instances, the docs do not
state that
