Re: [appengine-java] Re: Deploy Hangs - Please help

[Amir]

Having the same issue, i've been trying for a full 24 hours now... tried 
incrementing version, no luck. 

Google has a huge opportunity in taking the lead on cloud computing, but 
this is failure. We haven't released our app yet, i can only imagine 
how disastrous this kind of an outage could be for us after release.

[appengine-java] Re: Problem with exception on server startup when GAE sdk is in svn

[dilbert]

Not sure what you mean by make your .svn directories writable. I develop on 
linux and all the .svn folders have rwx for the user under which I develop. 
The development server runs as the same user. Should I make the adjustments 
for group and others? What about the subfolders inside the .svn folder? 
Should I mess with them too?

This is the exception I get:

I think this is the relevant issue on the issue tracker:

This is still an issue in 1.6.3.
Please fix this ASAP.

[appengine-java] malware detected in 1.6.3 java sdk?

[Sven Busse]

Hi,

i just downloaded the Java GAE SDK 1.6.3 and my Anti virus program 
(Microsoft Essentials)
tells me, it detected Malware in the zip file?!

Exploit:Java/CVE-2008-5353.WX

Allegedly it would be here:
appengine-java-sdk-1.6.3.zip.crdownload -> 
appengine-java-sdk-1.6.3/demos/guestbook/war/WEB-INF/lib/appengine-api-labs.jar

[appengine-java] Thread question

[Aswath Satrasala]

Hello,
In Appengine, after a request is served by a Thread, is there any
configuration to automatically discard the ThreadLocal data of the Thread.
I want to ensure that every request coming does not have the ThreadLocal
data that may have been stored by an earlier request.

Regards
-Aswath

I am already resetting the ThreadLocal variables to null in the first

is available.

[appengine-java] send channel message per page

[Luke]

is there any technique to send out only channel message if user is
viewing particular ajax page? what technique do you folks use to check
whether user is viewing particular ajax page? because it would be
waste of bandwidth to send out all channel messages to all users
(example 10,000) users if only 100 person is viewing particular ajax
page

[appengine-java] Re: Problem with exception on server startup when GAE sdk is in svn

[Rick Mangi]

Dilbert, see my reply on the ticket.

Max - that comment about svn being writable is nonsense. I wish you guys 
would talk to your own support engineers. I tried that solution with my 
premier support contact and it doesn't even make sense. svn directories are 
always writable. This is a bug, it's reproducible and it's going to be 
fixed in 1.6.4 (supposedly). The workaround is posted in my comment on the 
ticket. It took me weeks of back and forth to get the google engineers to 
see the problem. If someone had just tried it out I'm sure they would have 
seen the problem right away.

[appengine-java] Objectify + RequestFactory: Server Error: No class with kind '__Stat_Kind_IsRootEntity__' was registered

[Alexander Orlov]

Locally the code works fine, but on GAE this code (RF callback):
*@Override*
*public void onFailure(ServerFailure error) {*
*Core.log(error.getMessage());*
*Core.log("Error: " + error);*
*}*

...delivers this message to the Chrome console:

Server Error: No class with kind '*__Stat_Kind_IsRootEntity__*' was 
registered
Error: com.google.web.bindery.requestfactory.shared.ServerFailure@2a

Everything I've found about *__Stat_Kind_IsRootEntity__ *is that it's a 
Python related entity.

Yeah we noticed it was fixed at 12:12AM last night. I wish they'd give an

We've got a lot riding on GAE.

[appengine-java] Re: gae.parent-encoded-pk or how to combine gae.parent-pk and gae.encoded-pk?

[Niklas Lönn]

I have found a solution for creating owned relationships within an entity 
group, and still be portable, the best part, you dont need to manually 
handle key and parentKey. 
Check out my blog post at:

Hi All,

I am developing an application using GAE+Java+Spring+JPA+Google CLoud SQL.

[appengine-java] Re: Problem with exception on server startup when GAE sdk is in svn

[dilbert]

Thanks Rick for the valuable information. I do not like the idea of mixing 
jars from different versions just for svn's sake. For now I'll remove GAE 
SDK from svn and handle things manually which is a real pain. Hope they fix 
this issue soon.

How about using maven to handle your project dependencies instead?

Yeah, same here. The status pages didn't even register any issue regarding 
deployment.

[appengine-java] Re: Problem with exception on server startup when GAE sdk is in svn

[Rick Mangi]

That's on our roadmap, but I'm waiting for Atlassian OnDemand to start
supporting maven repos for artifact deployment. It's a good goal, but
adding an SDK to subversion shouldn't cause it to break...

[appengine-java] Understanding id generation (local test environment)

[Marcel Overdijk]

Hi,

I'm using Objectify to store data on Google App Engine.
When creating new entities a entity is put without it's Long id filled. 
This causes App Engine to assign a generated key automatically.

I would like to understand how this key generation works, and more 
specifically in the local test environment with new 
LocalServiceTestHelper(new LocalDatastoreServiceTestConfig()).setUp().

My observation is that when I e.g. do:
- create customer ==> id 1 will be assigned
- create customer ==> id 2 will be assigned
- create product ==> id 3 will be assigned 
- create customer ==> id 4 will be assigned 

So basically a sequential id is used for everything that is created.

I wonder if this can be customized so each datastore kind has it's own 
sequential key.


Cheers,
Marcel

[appengine-java] AWS, Signed Requests work locally but not when deployed to GAE

[reston]

Amazon WS (AWS) requires signed requests to access their Product 
Advertising API.  I have a working application running locally using the 
Play! framework that sends a signed request using java.net.URL and receives 
a valid "item lookup response", which basically can you tell whatever you 
might want to know about a particular product that Amazon sells.

The problem I'm running into is that, for some reason, these signed 
requests are somehow being _discombobulated_ when they are sent to Amazon 
via the same application deployed on Google App Engine.

The requests are clearly going out and the response from AWS is that there 
might be a problem with the signed request.  I can't understand why it 
would work locally but not in Google App Engine, and there are no errors or 
exceptions thrown.

Before posting code or getting into the nitty-gritty, I was wondering if 
anyone on this board has run into a similar issue using AWS via GAE?

Thank you very much.
