Also, if you just started coding on GAE, check out Objectify / Twig / Siena
etc. These are all very good frameworks.

You can have deploy your quatrz scheduler in EC2 and the only job is pinging

Will Quartz run in a backend instance?
http://code.google.com/appengine/docs/java/backends/overview.html
I don't remember offhand if Quartz uses threads. I'm pretty sure it does
which will mean it *won't* work, but I figured I'd throw it out there.

The OP mentioned that cron was too limiting for his particular needs.

Have you taken a look at the scheduler that has shipped? It should be under
Application Settings. If there's anything there that you think might be
needed, please let us know.

It may be a known bug to you, but perhaps if someone actually register
it in Google's issue log then they would know about it?
There are some issues with JSF session-scoped beans. In some cases
session bean changes are not replicated to another server instances.
For details and workarounds look at this post

Hello,
Thanks for your contributions for a GAE-Java CMS.
I had a look at the code of claymus. It seems that you use the
combination of gae and gwt, this is a very interesting point.
But on the client side, some architectural questions come to my
mind...
I don't understand your separation of
Hi,
I need help to use Provisioning API with OAuth authentication, the following
problem occurs, how to do domain validation in java api ? In Python it is
possible to know the following code.
service = gdata.apps.service.AppsService(domain=consumer_key)
A few comments:
1. That's more of a 1:1 relationship
2. Try to avoid using the term child. The reason is that when you start
working with entity groups, you will confuse yourself with terminology. If
you don't understand entity groups yet, take a look at these docs:
No body can answer that without knowing exactly how your app uses billed
resources.

One more option: you can set ETAs in task queue tasks. That is, when some
action occurs, you can say, Run this at 6:30am, and the job will run at
roughly that time:

Hi Ikai,
I cannot find answer to:
1) Will the limit of 30s to start an application be lifted?
The other question seems to be answered since the changes in 1.5.2
(http://code.google.com/appengine/docs/adminconsole/
performancesettings.html#Setting_the_Minimum_Pending_Latency)
On Jul 22, 4:24
I haven't heard any plans to lift the 30s load time to start an application.
30s+ loading time seems pretty bad to me ...

Yes might be, but frameworks like Grails need a longer startup time.
It does not matter for any application server nor cloud provider
except GAE.
That's why I'm asking about future working of scheduler.
Further, if I keep up enough instances I would not bother the startup
time at all...
I'm
What's the startup time on Grails now?
I can ask about the 30s startup time, but I'm sure there are some pretty
serious consequences to an app with a 40s-50s startup time. I'm a bit
surprised, honestly, because even a JRuby on Rails app shouldn't take more
than 30 seconds to startup.
Ikai Lan
Honestly I don't know what the current startup time for Grails on GAE
would be now. Also depending on what plugins installed etc.
Current version does not even work on GAE. I was thinking about trying
it out again but remembered the 30s limit I hit some time ago.
So I asked this question on the
