Hi,
I wonder if somebody else has seen this error before. My application has a
Servlet Filter (that sets Namespace) for all urls, and, from time to time,
the Filter receives a null as value for "chain" parameter from the platform,
so I get a NullPointerException as I try to follow the chain wit
Hey
I have an Entity which contains a List property that stores
child entities. I have found a bug in my app where during concurrent
modification of child entities all of the children in the parent
entities list will be deleted.
Firstly, why does this happen? Surely it'd be better to throw an

I've been running an application successfully for some time on the app
engine. During last week I've couple of times tried enabling threadsafe in
my app. It seems to randomly cause issues with retrieving or storing data
with JDO. What I see when I start to get these issues is this (I've replaced

Hi,
creating a ScriptEngine in a servlet like this:
ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByExtension("js");
(or using the String "JavaScript" instead of "js")
does not work, engine is null.
doing: logger.warning("num engines=" + factory.g
Hey google team, the backends javadoc reference hasn't been uploaded to the
app engine docs area. I just read it locally so it's not a big deal but
thought you should know.

When running a backend, what is the suggested method for something like
this:
while(true){
doSomething();
Thread.sleep(1000);
}
Do you have any tricks to replicate this behavior?

The latest app engine announcement that most App Engine for Business
functionality would be rolled in to App Engine. Does this mean that all
current developers will have access to the SQL data store or will this just
be for paying customers? If yes then will the access be through JPA or JDBC?

I am evaluating imagesService.applyTransform() to transform images(from URL)
to specific width/height.
It's documented that PNG is supported. But it seems it doesn't understand
some PNG file.
for example :

Anyone ?

Hi,
Don't know if what you do is possible but why don't you just obtain
the data that you need from the other application via simple requests
to servlets delivering the needed data.
By using Java standard object serialization, you can achieve what you
need whatever the object class via a unique a
Hi,
Do you have the issue on your dev machine or on productive

but that would work ok on live machines

Hmmm, there a

There are two sides to the App Engine API: the client and the server. The
client side (appengine-api.jar) lives entirely in "user-land". If you so
chose, you could create your own version of these classes. In the end, the
client ends up talking to the server through a binary protocol in ord
I've been programming to the jcache interface that's included in the
appengine sdk
javax.cache.Cache and that still works in SDK 1.5.0.
appengine's service locator (MemcacheService) finds the implementation
for the interface.

I have the same issue:
Eclipse cannot find:

I need the GCacheFactory when I set the expiration:

I see now that the documentation online is erroneous.
I found the sample xml file in the sample Hello project and copied it.

Just a quick summary, the servlet spec requires that a servlet
container such as appengine
provider an implementation for a service. Those jars such as servlet-
api-2.4.jar are needed
at compile time. They are sometimes provided by the servlet container/
engines at run time
in a global directory
This is on our radar but it's not yet supported.
