Hi All, I have a year's experience writing client code but none with server stuff. I want to restrain the question a bit so I'll simplify what I'm trying to achieve. I want to write server code such that two clients (Browser or iPhone / Android) can connect, when two player have connected they see a timer count down to zero. The clock ...

after launching your app on google app engine. you can use the 'logs' page in the admin console to see a how many requests were made, any http:// 404 errors etc. It's hard to make sense of how many visitors you really got and or others. Am I missing something here ? Can somebody tell me how to read logs on a google app engine. Many ...
This is a very noobish question, so I apologize in advance! I have two time stamps for start and end of the event. They are stored in as datetime.datetime in UTC. What I need to do is figure out the duration of the event. I tried subtracting one from the other, but receive error: Traceback (most recent call last): 02. File '/base/pyt...

For an application build on Spring MVC + Groovy + Google App Engine i need simple XML serializer/marchaller. I'v tried: XStream - it doesn't work on Google App Engine, because it uses restricted (at GAE) classes Jaxb2 - it doesn't work with Groovy classes, because groovy class have additional (hidden) fields (like metaClass, etc) Xml...

I am trying to deploy struts2 with the rest plugin onto the Google app engine... I have copied the showcase files to a GAE project created in Eclipse. The compilation and upload works fine. When I hit the index.jsp, which forwards me to /orders I get a 404. When I check the logs, there is no error, just a warning (as below). The Orde...
My code worked fine when it was all in one file. Now, I'm splitting up classes into different modules. The modules have been given the same name as the classes. Perhaps this is a problem, because MainPage is failing when it is loaded. Does it think that I'm trying to inherit from a module? Can module/class namespace collisions happen? M...
I've been slowly and a bit painfully working my way up the datastore/JDO learning curve in GAE. Recently I've found a framework called Objectify that is supposed to be somewhere between the very-simple Datastore native API and the complex JDO. I've been reading up on it and it does seem attractive. What I want to know is, if anyone ha...
Hello, I'm a newbie in JDO. I use eclipse. After I use (PersistenceManager) pm.close for test, now I delete this pm.close. However I still could not find a way to open or create a new one, even after I restarted the computer. Every time, PersistenceManager show this error, Object Manager has been closed And I could not find a way to d...

Suppose I have class Foo(db.Model): bar = db.ReferenceProperty(Bar) foo = Foo.all().get() Is there a way for me to do foo.bar without a query being made to Datastore? The docs say that foo.bar will be an instance of Key, so I would expect to be able to do foo.bar.id() and be able to get the id of the Bar that's associated with foo...
I've heard how browsers can receive gzipped pages from the server. Can they also gzip form data that they send to the server? And if it's possible, how would I decompress this data on the server? I'm using AppEngine's webapp module, but a general explanation / pointers to tutorials would be sufficient. I've done some googling to no avai...

I need to store settings for my Google App Engine project. Currently I have: class Settings(db.Model): rate = db.IntegerProperty(default=4) ... And when I want to use it: Settings.get_or_insert('settings') This feels clumsy so is there a better way (without using Django)? ...
