Hello,
our application recently started producing exceptions like:
com.google.appengine.api.datastore.DatastoreNeedIndexException: no
matching index found..
or
Server error 1:

matching index found..
What does the web page where you get the java.io.NotSerializableException look
like?
I tried playing around with the javax.faces.context.Flash features on the
http://jsf2gae.appspot.com/ site. The first page, flash.xhtml, has the
following source:

Hi, task queues are just a way to call a url some time in the future.
As Jason mentioned above, for a tasks "handler" you should probably
just create a servlet (extend HttpServlet) because you do not need to
generate a nice webpage as the result of the call - no one will see
it. In the HttpServlet

My GAE logs are timestamped with a -0800 offset. Is there a way to
control the offset? For instance, I'd prefer my logs -0600 (my local
time) or - (UTC). How/Where would I configure that?
Thanks,

Another way you could look at is that by using things like customerId and
accountId as your database primary keys you're mixing your business stuff with
the database persistence stuff. If you create a primary key in the base class
and call it something like id, you can still have the accountId
What method gets called in your code when your app receives a GET request? Or
a POST request? I think that's what you're looking for. Unfortunately the
documentation for these frameworks sometimes tries to sugar coat things and
hide ("abstract away") these low level details, or they assume it

Does anyone else have any idea how to explain what the entry point is

Thanks for your reply. I guess that's what I will do in my next app.
However, in the existing app the identity fields are already defined
in the subclasses, and they have different names too, e.g. Account
would have accountId, Customer would have customerId, so I cannot move
the ID field to the roo
The
USER('a...@gmail.com')
part looks strange to me. That syntax says to me that there's a database
function USER(), which I'm guessing there is not.
I'm thinking you want to do something like
select ... where user.email = 'aaa.gmail.com'

Heh, I'm on the flip side; I don't know anything about GWT.

Thanks; I looked at that as well. If I remember correctly it hasn't been
updated since May of this year.

Google App Engine has a Maven Plugin project.

Unfortunately there is no manual and I can't figure out how to use it,
what else may be necessary, how to configure them, what's the
relationship with Apache Eclipse Maven plugins.
There are sample Project t

Dear member,

Joe,
Your web.xml looks good and a quick look at the JSF RI source code shows that
it is not Serializable (I just peeked at the JSF 2.0.2 code which was released
on the 10th and the class isn't Serializable there). As described in the
source code for the javax.faces.context.Flash

Thanks for this Rusty, Im not sure I understand all of it right away
(perhaps with more investigation I will work it out)
However Its worth mentioning that as far as I know Im not using Spring
or Stripes or Struts (not even sure what any of these are!)
I am using native GWT (v2.0)/GAE (v1.2.8) and
I just checked the DN docs and was able to answer this (dumb) question
myself.
DN's logging can be configured using its logging categories.

Thanks for the feedback guys. I'll try with a long and assign it using
integers, hopefully this should work.
