[appengine-java] Objectify index question
If we index a field after many entities have already been created, how can we get the app engine to re-index all the data for the entity? Do we have to 'touch' (update) each and every instance of the entity to get the index build on that field so we can query using the console?

[appengine-java] Reoccurring DeadlineExceededExceptions at request.getSession()
I have seen, for some time, DeadlineExceededExceptions in our apps log where it appears to be hanging on a request.getSession(). In our app we have an authentication filter that sets and removes an attribute on the session and this error happens at least twice a day. Has anyone else seen this behavior? Does anyone know what going on here? George Holler -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Auto generating datastore-indexes.xml during unit tests
Hi Didier, thanks for your reply. Those instructions are for generating an index file while running the dev server and hitting it locally with your browser. What I am talking about is during running JUnit test cases using the LocalServiceTestHelper. That helper lets you write unit tests against the datastore and seems ideal to be able to generate indexes from since your unit tests should hit every kind of query you have.

[appengine-java] Auto generating datastore-indexes.xml during unit tests
Is it possible to auto-generate the datastore-indexes.xml while running JUnit tests that use the LocalServiceTestHelper (with LocalDatastoreServiceTestConfig)? It seems like it would be great to have the file automatically generated and then deployed with maven. Unfortunately I don't see the file being generated.

[appengine-java] Occasional NoClassDefFoundError
In the last couple of days we've been seeing java.lang.NoClassDefFoundError exceptions in our log for our GAE Java app. The class in question is one of ours that works and has worked for months. What could this be? Is this caused by problems with a static server behind the scenes? Has anyone else seen this?

[appengine-java] Re: Why should app startup times be a problem.
Thanks for your replies. I think we would want an option to pay to keep at least one instance "warm" and ready to go at any time (I don't know what makes sense for a fee though). And as Guillermo says, that won't help us as new instances are needed to scale. There could be a fee for paying accounts to get those special startup requests, and I also don't know what makes sense for a fee there. It would also need to be able to handle more than 30 seconds, ideally it could be a task that keeps gettings called until it returns a 200-299 status. The url for the task could be specified in the appengine-web.xml. G -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Why should app startup times be a problem.
When GAE is load balancing your app, and it decides to start up a new instance, why are they sending a client request as the first hit to your app? Unless your app is trivial, you're going to have some startup time. It's not a good job of load balancing if requests are sent to an instance that isn't even started yet. This is killing our app. The load balancer should get an HTTP 200 back from our instance before sending any real traffic that way. Am I off-base here? Is anyone else deploying an app with a rich client and a datastore back-end where this isn't a problem? I couldn't find anyone at the Server Side Java Symposium last week that was deploying to GAE.

[appengine-java] Re: Enable billing to avoid HardDeadlineExceededError?
Okay, the first thing mentioned was that you are using Spring. We are doing an experiment removing Spring in our app to see what impact it has on startup time.

[appengine-java] Re: Enable billing to avoid HardDeadlineExceededError?
No, the 30 second limit is a hard limit. If a request can't finish in 30 seconds (or somewhat earlier), you get an exception. You then have an undetermined amount of time before the app engine kills your request and returns a 500 status code. You wouldn't happen to be using Spring, would you?

[appengine-java] Re: Exception When Uploading Application To AppEngine
I'm seeing the same thing here. All of a sudden I can't deploy to the cloud. I'm using gae 1.2.2, and I'm getting the exact same error. The only thing that may have an effect is that I had someone else on my team deploy to the same account (different app id), since then I haven't been able to deploy. I can't believe that you can't have more than one person ever deploy to an account. Any guidance would be appreciated. Thanks.
