Pretty weird. Let's hope someone from the GAE team peeps into this thread. I
have thousands of tasks being generated every minute and there are errors
when they are executed. I'm hoping they don't get "duplicated". There's no
way for me to know so if what you say is true then it's trouble for a
When a task fails, the "same" task would be retried again. Ideally if you
have just one task in your system and that fails a 100 times at the end of
the day you should still have only one task in the queue.
Are you sure you do not have any logic in the url that the task calls where
you create a
You would need to specify a timeout and if there is no activity for
that time frame sessions would need to expire. To be safe about
expiring sessions and at the same time wanting to keep them alive,
what I can suggest is do this :
Put a simple ajax call on the page. Make it call your app every 20
I've been on GAE from the start of 2010. This thread still seems
delicious. Thank you all for posting the wonderful comments.

Have a look at the Datastore "Key" thingy. The keys generated are
unique across the system IMO. Not sure though but that's what I
remember reading somewhere.

GAE runs multiple instances which means your code would be run on
multiple JVMs as well which means the static field will be multiple as
well. A lot of "as wells" here but I hope you get the point.
Use statics for constants that do not change. For everything else
persist either in memcache or data
Which OS are you using? Windows 7?

Can you provide a link to the question you might have posted on this

I have my app on Java and PayPal provides an official java API for
Google Appengine. It works great for me!

As far as cache expiry is considered, its a guarantee that the cache
won't expire before the set expiry date (it might still expire in case
of failures etc).
Basically, there's no real guarantee that the cache will expire after
the time that you have set. It's just that it won't expire before the

Was searching twitter, others seem to be facing the same problem.
Please treat this on priority, my entire site http://www.justunfollow.com
is unusable right now due to the error.
A lot of users are stuck due to the error.

However, it works in my development environment on my PC. Please help

IMO, it wouldn't have any changes but if you put in a LOT of them then
for obvious reasons they would affect performance.
It isn't a good practice to have syso's in your code for testing. Use
Logger to do that. It's helpful and you can view outputs in the
production environment as well!

Session isn't lost but session use is discouraged. You have memcache
which is pretty fast in retrieval. Of course, every once a while even
the memcache can be invalidated due to various reasons. While relying
on memcache you need to be sure that in case the value returned is

Hi All,
I need to clear a few doubts. Let's take an example so that you know
what my doubt is :
I have a User object and each user performs an operation - say a
status update.
User {
private Long id;
private List updates;
}
Now this seems all good but if I'm not wrong Appengine has no

For count, you need to implement sharded counters -

The code required to do the same is provided. Just understand what
sharded counters are and make use of the provided code.

Hi,
I keep getting 500 server erro at regular intervals. IMO it's the
Google App engine that is facing issues. This is really frustrating
now because my apps usage has increased a lot and I keep getting
complaints about it from users. I am not able to reproduce, there are
