[google-appengine] Re: Google auth default credentials for GAE standard 2nd Gen (Python)

[Eric G]

It was more a question because the documentation was unclear for 2nd 
generation standard GAE environments.  
I have no problem using an explicit credentials file - in fact I prefer 
that to the magic of default credentials, and using the GCE metadata 
service involves an extra network hop if I'm not mistaken.

[google-appengine] Re: Second gen GAE Python 3.7 > Cloud SQL - MySQL

[Eric G]

Thanks for this. The second link is to the flex environment documentation. 
Are you saying that App Engine standard 2nd gen uses the same method of 
connecting to CloudSQL instances as flex, i.e. via the unix socket  
/cloudsql/INSTANCE_CONNECTION_NAME ?  If so, it would be helpful to have 
those instructions/example on the first link (to standard 2nd gen) as well.

Personally, I would like to see an example that doesn't depend on 
SQLAlchemy + Flask, otherwise people may think they have to use those. I 
guess it's not hard to figure out but just some acknowledgement that you 
can set your own environment variables and manually use them to connect 
with pymysql or whatever adapter.

[google-appengine] Google auth default credentials for GAE standard 2nd Gen (Python)

[Eric G]

It appears that the google-auth default credentials 
<https://google-auth.readthedocs.io/en/latest/user-guide.html#> will not 
work for 2nd generation standard environments, at least not for Python at 
the moment, as it requires the app identity/user API.

Is there a plan for getting default app engine credentials to work in 
another way?  Or is the recommendation to set the 
GOOGLE_APPLICATION_CREDENTIALS env var to point to the service account file 
manually?

Thanks,
Eric

[google-appengine] Re: Back to GAE after some years

[Eric G]

Re. NDB, there is an open source library very similar to it, Python 3 
compatible:  https://github.com/Bogdanp/anom-py.  I can't say I've used it, 
but I highly respect the author's other libraries. 

It includes transparent caching, though with GAE flex or standard Python3 
you have to run your own memcache service.  
See https://cloud.google.com/appengine/docs/standard/python3/python-differences

[google-appengine] Secrets on App Engine Flex

[Eric Hauser]

The standard method of storing a secret in GCS encrypted via KMS generally 
works fine. However, the Service Account documentation for App Engine Flex 
states 
(https://cloud.google.com/appengine/docs/flexible/python/service-account):

"Do not modify the permissions of the App Engine flexible environment 
service account."

What's the recommended way to give a Flex container the ability to decrypt 
a secret if you can't grant permissions to a KMS key?

[google-appengine] Framework Recommendations for AppEngine Java8 Standard

[Eric Martineau]

When we started building AppEngine Java7, the community recommendation and 
examples were centered around using Guice+Jersey.  Despite having a long 
history with SpringBoot, our company invested in Guice/Jersey 
infrastructure for AppEngine.

Since the release of java8, there are a few observations that lead us to 
wonder if Guice+Jersey is still the recommended path:

* The emergence of Spring Cloud GCP (primarily developed by Google)
* Inclusion of SpringBoot examples in getting-started-java (not seeing any 
Guice/Jersey examples)
* A Google Codelab dedicated to SpringBoot in AppEngine

Is there any formal/informal recommendation for Java8 AppEngine between 
Spring vs Guice+Jersey?

[google-appengine] Google Cloud Libraries for Appengine Standard

[Eric Martineau]

Java8 opened up the possibility of using google-cloud-java (grpc) libraries 
within AppEngine standard.  The newer libraries are nicer to work with from 
a development standpoint, but I'm not sure if there are any significant 
drawbacks to using them within AppEngine Standard.

Can anyone provide guidance on how to approach the inclusion of GRPC 
libraries in AppEngine Standard Java8?

Specifically, I'm thinking of two things:

- Push/pull subscriptions for PubSub
- StackDriver Logging

Re: [google-appengine] Re: ~20ms latency between two servlets, same project, is that about right?

[Eric Hubbard]

Thanks for the great info!

I'm running standard and java8.  My latency times were much lower 24 hours
later.  I went from a chaotic..20-50ms...   down to a very stable ~12ms 24
hours later.  Maybe some  environmental things were going at at the time.
These numbers were reported by my code, and also seen by the log traces.

[google-appengine] ~20ms latency between two servlets, same project, is that about right?

[Eric Hubbard]

Playing around with splitting my project up into separate services, and 
invoking via URLFetch between them.  I'm seeing anywhere from a 20-22ms 
latency on a very basic remote side side.  I'm using Kotlin compiled down 
to java8.   (the ping servlet is in java8...)... 

So.. does ~20ms seem about right? 



val fetchOptions =FetchOptions.Builder.doNotFollowRedirects()
val instanceHostname =getInstanceHostname("default", "1", "$serverNum")
val u = URL("http://$instanceHostname/ping;)
val req = HTTPRequest(u, HTTPMethod.GET, fetchOptions)
val timer = Stopwatch.createStarted()
val fetch = urlFetchService.fetch(req)
val rc = fetch.responseCode
timer.stop()


and then this in the /ping servlet


protected void doGet(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException {
PrintWriter writer = response.getWriter();
writer.println("Hello there from the backend");
writer.flush();
}

[google-appengine] Re: Handling API versioning issue

['Eric So' via Google App Engine]

Sorry that this reply thread does not show up in my inbox. I will open a 
bug / issue to track this. 

And I found out from one developer that the application needs to setup 
different classes for different versions. We need to deploy the whole 
application with different versions in one jar or war to support multiple 
versions in one endpoint.

[google-appengine] Handling API versioning issue

['Eric So' via Google App Engine]

Hi All,

I just followed the instruction from our external documentation page, 
https://cloud.google.com/endpoints/docs/frameworks/java/handling-api-versioning.

I have an API application deployed with application version = 1 with api 
version v1.0 two months ago. Today, I am trying to deploy a new API version 
v1.2 or v1.3 to the same application version. I assume the following 
endpoints should work:

1) https://1-dot-x.appspot.com/_ah/api/user/v1.0
2) https://1-dot-x.appspot.com/_ah/api/user/v1.2 or 
https://1-dot-x.appspot.com/_ah/api/user/v1.0

However, when I opened the https://1-dot-x.appspot.com/_ah/api/explorer 
in the browser, I could only find the older version we had. But not the new 
one. I tried to curl or ping the url with the new API version. It returns 
404 NOT FOUND.

I want to ask if it is possible to redeploy Java App to the same app 
version. Also, do we need to keep multiple version of source code in the 
same repo and re-deploy everything again?

Regards,
Eric So

[google-appengine] Re: Discovery Doc generation missing "format" tag for doubles

[Eric Wasserman]

Thanks for the reply, Alex. I wasnt clear in my question, but I have also 
upgraded my iOS code to use the new libraries generated by the service 
generator off of the REST discovery docs. To make the library generation 
work I was forced to manually add the "format": "double" key/value to all 
double number types. Any idea why the discovery doc generation is leaving 
that pair out?

See my related question

[google-appengine] Discovery Doc generation missing "format" tag for doubles

[Eric Wasserman]

I upgraded to Cloud Endpoints 2.0 recently. I never saw this issue when 
generating the now deprecated RPC doc. I believe there is an issue with 
discovery document generation, where it doesn't create the '"format": 
"double' for double fields. creditAmount below should have the format tag. 

Fixing this manually for all the similar fields fixed the errors when 
running the service generator for iOS client library generation. Has 
anybody else encountered this?

See:


"creditKickbackKash": {
 "httpMethod": "PUT",
 "id": "servUsApi.admin.creditKickbackKash",
 "parameterOrder": [
  "userId",
  "creditAmount"
 ],
 "parameters": {
  "userId": {
   "format": "int64",
   "location": "path",
   "required": true,
   "type": "string"
  },
  "creditAmount": {
   "location": "path",
   "required": true,
   "type": "number"
  }
 },

[google-appengine] Can't delete property of entity, or even the entity itself (datastore)

[Eric Irish]

I've got an entity that contains a JSON array per property. One of the 
properties has become rather large: the index count is 14,697 for a total 
of 1.5MBs. I need to delete this property, or the whole entity in general, 
but it seems to be impossible. I've tried editing the property to manually 
remove much of the JSON array. I've tried deleting the property inside of 
the entity, and I'm met with a "pending deletion" message, which never goes 
through. I've tried deleting the whole entity from the admin console, but 
when I try to track the job by the ID, it errors out. Has anyone run into 
this before?

[google-appengine] Re: service account auth to Calendar API stopped working Oct 20

[Eric G]

Thanks. It seems to work now, oddly without even doing 
credentials.create_delegated (but I may be mistaken, I only tested it 
briefly in an offline context. In my GAE application, I've switched it to 
use standard 3-legged OAuth instead of service accounts).

Anyway, if credentials.create_delegated is essential for service accounts 
with DwD, I would propose making it more obvious in the documentation 
<https://developers.google.com/identity/protocols/OAuth2ServiceAccount>. I 
carefully read that page several times and missed it. The way the document 
hierarchy reads, it looks like it is on the same level as "Google App 
Engine", "Google Compute Engine", and "Other". So if you are looking for 
GAE instructions, you may think it doesn't apply to you. I would suggest 
moving that up one level in the hierarchy so you'd have:

1. Create a Credentials object from the service account's credentials and 
the scopes your application needs access to.

2. If you have delegated domain-wide access to the service account and you 
want to impersonate a user account, use thecreate_delegated method of an 
existing ServiceAccountCredentials object. 

3. Use the authorize method of the Credentials object to apply the 
necessary credential headers to all requests made by an httplib2.Http
 instance. 


I would have left this as a comment, but I don't see a way to give 
documentation feedback on that page.

Thanks again,
Eric

[google-appengine] Re: service account auth to Calendar API stopped working Oct 20

[Eric G]

Details below. I also opened an issue on the apps-api-issues:
https://code.google.com/a/google.com/p/apps-api-issues/issues/detail?id=4870=Stars%20Opened%20ID%20Type%20Status%20Summary%20API%20Owner

I successfully switched the app to use 3-legged OAuth vs. service account 
OAuth, but still would like to get to the bottom of this, as I'd prefer to 
use service account OAuth for testing and maintenance programs that hit 
this API, and also for the benefit of others who may be having the problem.

G Suite tech support suggested after setting up DwD you may have to use 
credentials.create_delegated('some.real.u...@example.com')  -- as mentioned 
on this page 
<https://developers.google.com/identity/protocols/OAuth2ServiceAccount> (but 
without any indication that it's necessary, and very easy to miss). I have 
not tried that but will in the next day or two.

[google-appengine] service account auth to Calendar API stopped working Oct 20

[Eric G]

I have a GAE project (python 2.7 runtime) that uses the Google Calendar API 
v3. Up until last week, I had been using the default GAE service account to 
connect to the calendar API, and the service account was given read/write 
permission to the calendar under calendar sharing settings.


Since last Thursday Oct 20, the service account cannot write to the 
calendar (events.post or events.patch) -- returns a 403 Forbidden -- and 
reads (events.list) return 200, but no records. Checking the permissions 
for the account under calendar sharing, it has been changed to "See 
Free/Busy only".


I believe this is related to this announcement from Google about winding 
down OAuth 1.0 service accounts on Oct 20: 
https://developers.googleblog.com/2016/04/saying-goodbye-to-oauth-10-2lo.html


The recommendation seems to be to grant Domain Wide Delegation to the 
service account: 
https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority


We have followed the instructions on this page, but it doesn't work using 
either AppAssertionCredentials or ServiceAccountCredentials.

[google-appengine] Re: Request was aborted after waiting too long to attempt to service your request

[Eric Froemling]

I started seeing this too a day or so ago too (somewhere around 9-10PM EST 
monday night). For me it's not limited to deferred requests; I'm seeing 
large numbers of these failures across all my requests.  I've found I can 
keep things under control by cranking max_idle_instances way up (I usually 
leave it at zero), but I really hope this gets resolved soon.  I also 
noticed this exact same thing happening several weeks back; in that case it 
lasted started on a saturday and seemed to get resolved the following 
monday.

Anyone else seeing this or know what could be happening here?
Thanks,
-Eric

 For the past few days I see a lot of aborted calls with the message

 It comes from deferred and other queued requests, I have not seen any 
 change with interactive calls. Has anybody else noticed similar behavior? I 
 use the scheduler with the default settings. Has anything changed?

[google-appengine] Re: Google App Engine Task Queue: googleapi: Error 500: Backend Error

[Eric G]

Hey, thanks for this Frank(s)!  Solved my problem too. I'm submitting a 
feedback request to Google's documentation on this.

One other thing I had to do was make sure my project in the URL was 
prefixed with s~, as suggested in responses to the SO question here:

 Frank, yet another :)

[google-appengine] Re: Google Code issue tracker cleanup

[Eric Tray]

Obviously getting feedback from users is not too vital to you guys 
otherwise you would'nt have ignored the Issue Tracker for 4+ years. How is 
it that no one is held accountable for this? How is this acceptable for a 
company such as Google? 

If it takes you this long just to fix the issue tracker, I can only imagine 
how long it will take for the actual issues themselves to get resolved. 
Maybe 5 years later we will actually get Servlet 3.0 support. Probably not 
though.

 Over the past few years we have fallen behind on updating our issue 
 tracker on Google Code. But since getting feedback from our users is vital 
 to us, we will be renewing our focus on making the tracker useful to you.

 We must work through the large number of open issues which exist today. 
 Many of the older issues issues represent popular feature requests, but 
 others were opened long ago and are no longer relevant to the person who 
 opened them or to the App Engine community.

 We wish to fix this so that developers can easily find and follow issues 
 which apply to them. So, over the next few weeks we will review open issues 
 and close those that are obsolete and merge related issues together when 
 possible.

 There is much work to do here, and in some cases we may inadvertently 
 close issues which are still relevant and important. If an issue which 
 affects you is closed and marked as obsolete or as a duplicate of another 
 issue, please comment on the issue so we can take another look.

 How you can help

 --

 1. Check for a duplicate first. If so, star that issue. We often do sorts 
 by number of stars, so if it's a common issue, lots of duplicates can cause 
 us to miss it

 2. Write a clear, concise bug report. This is a report that needs to be 
 read several times. Write very clearly reproduction steps, OS, SDK version 
 and post code if you can. If we can't understand the bug report, we will 
 close it. 

 3. Follow up. We will sometimes post questions in the bug. If we don't 
 receive a response, we will close the bug. Also - if it turns out to be 
 user error, it helps us a lot if you post your fix. This sometimes helps us 
 expose places where we can improve our documentation.

 Thank you all in advance for your support and commitment.

[google-appengine] Disable permissions checks in the dev server - it's causing major problems in Ubuntu

[Eric]

I'm having a major problem running my app on the dev server.  I'm using 
Thymeleaf and Spring 4.  I'm getting permission problems like this:

java.lang.IllegalAccessException: Class 
com.google.appengine.tools.development.agent.runtime.Runtime$21 can not 
access a member of class 
org.thymeleaf.spring4.requestdata.RequestDataValueProcessor4Delegate with 
modifiers public
at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:105)
at 
com.google.appengine.tools.development.agent.runtime.Runtime$22.run(Runtime.java:488)
at java.security.AccessController.doPrivileged(Native Method)
at 
com.google.appengine.tools.development.agent.runtime.Runtime.checkAccess(Runtime.java:485)
at 
com.google.appengine.tools.development.agent.runtime.Runtime.checkAccess(Runtime.java:479)

even though it definitely should be working.  I am told that it all works 
fine on the actual app engine (deployment) but it's not working on my 
Ubuntu desktop machine.  I'm pretty sure this is some problem in 
interaction between GAE and the Ubuntu JVM.  It's absolutely killing me. 
 It seems like the simplest solution would be to turn off all permissions 
checks on the dev server.  I've tried to do that by recompiling but I'm 
having a hard time with the guild process (I should recompile Runtime.java 
but I'm not getting the dependencies to work for that).

Any suggestions on this?  I can't over-emphasize, this is a totally fatal 
problem for anyone developing on a Linux desktop.  I'm about to pull the 
app from GAE and switch to some other service, over this one issue.  I'm 
eager to hire anyone to help me rebuild the dev server if that's possible. 
 Thanks

In the application above 

c:when test=${user != null}

is not evaluating to anything and I am greeted by *Welcome! Sign in or 
register*. Since I am logged into Gmail it should display *Welcome! You can 
sign out *
*
*
I am wondering if req.setAttribute(user, user); has set anything at all. 
It does not seem like it. I see what looks like a good call to User user = 
userService.getCurrentUser(); in the servlet. I don't see the problem yet. 
Does anyone know what could be wrong with the code?

Even though I am signed in to my Google Account in Chrome I am still seeing 
Sign in or register not Welcome as I expected. When I click Sign in I am 
forwarded to a page with one text field to enter an email and a check box 
to sign in as administrator. There must be something wrong because I think 
since I am logged into gmail it should display welcome?

Thanks in advance...

[google-appengine] Re: Users and Google Accounts

I since deployed the application to make sure that perhaps it was not some 
limitation of the eclipse development environment and I still see the 
home.jsp not recognizing the user variable even though the browser is 
logged into gmail.

Re: [google-appengine] Re: Attention Java MapReduce users

[Eric Jahn]

Tom, 
The files I'm searching for in datastore viewer were finalized, and I was 
able to search for and find more recent finalized blobs using SELECT * FROM 
__BlobFileIndex__ WHERE __key__=KEY('__BlobFileIndex__', 'SoMeKeyHere');
and for still writable this works: 
SELECT * FROM __BlobFileIndex__ WHERE __key__=KEY('__BlobFileIndex__', 
'writable:SoMeKeyHere');
However, for the keys of the missing file, the query in the datastore 
viewer returns name must be under 500 bytes.  Those 500 byte keys were 
successful for accessing/writing to the original files with my AppEngine 
code before they were finalized, so why is this length a problem now?  Or 
was exceedingly long key generation part of the Files API bug?  I still 
need to access those files, since they took a lot of expensive backend time

 If you have the writable file name you can use the datastore viewer to 
 find the finalized file name. 
 Go into the datastore viewer and enter the gql query: SELECT * FROM 
 __BlobFileIndex__
 This will show you the mapping. Then you can narrow it down by specifying 
 the ID/Name as the writable file name.

 GAE is still blocked in mainland China.

 The regime is constantly monitoring the network traffic and servers and
 taking actions whenever it sees fit. So I don't believe any simple method
 can claim access for 'all users' from 'all parts' at 'anytime'. If one
 server is deemed a 'threat', the whole DNS may be blocked, as is the case
 of GAE.

 Good luck,

Re: [google-appengine] Re: GAE access from mainland china and cloudfare

Thx you guys for all the suggestions (and debating ;))

Will, our site is for general public, not mission critical, so infrequent
downtime or a few minutes glitches could be acceptable. Guess from your
description it's not ideal solution but acceptable, and should apply to us
too.

Jeff, full-time SSL, according to you, should further minimize chances for
getting blocked. i think we can consider that too, thx

Brando and Damon, thx a lots for the debating and i learn a lots from it.
Damon, we want to launch a site in China and I prefer to run on GAE (just
becoz i'm more familiar with dev on GAE than like EC2 or others) If you
have any advises /settings for using CF to help us to minimize downtime /
enhance performance / increase rank on SE (or have actual figures for
downtime with GAE apps on CF in China) , please drop me an email. thx!

cheers,
eric

[google-appengine] exceptionally high latency, causing bad experiences and high hosting cost

[Eric Ka Ka Ng]

from around last 12 hours, we see an exceptionally high latency on some of
our gae apps. before requests on average takes 200ms-1000ms. now it can
takes 2000ms - 5000ms. I try to measure the time as local client. like make
10 requests, 1-2 times the latency is normal 1s, half of the time is like
2s-5s, sometimes it even takes 10-20s!!

as a result, it also doubles the number of instances started by GAE, and so
as the frontend cost.

does anyone observe similar problem recently, or it's only me? is it
google's infrastructure prb, or anything i can do? if it's google's
infrastructure prb, i dont think it makes sense to transform such bad user
experiences (high latency) into doubling our hosting cost

yes, i'm sure that's an internal bug for them and many others face the

  if
 you have questions or issues regarding billing..  No answer for 3 hours
 and counting.  I raised an issue about it, still no answer.  Finally I'm
 posting here, having reached a final dead end.

 There are so many ironies here its almost funny.  I exceeded my quotas
 because I was experiencing lots of problems with high latencies and warmup
 requests taking too long.  Some of my customers had expressed concern that
 the system couldn't handle the load.
 Second irony is due to the high latencies experienced, some customers had
 started to question if Google was a noddy platform and couldn't scale.  I
 of course went to great lengths to discuss that I'd in fact chosen this
 platform due to its robustness and scalability.  And then its down for over
 3 hours due to a billing bug.

  I agree I should have anticipated the quotas actually being exceeded, but
 given that I missed that moment I would have hoped the situation would have
 been recoverable in less than 3 hours!  Beware ALL.

 If there is someone out there who can help, please tell me how I get the
 app running again ASAP.

 many thanks.

[appengine-java] Re: java.lang.OutOfMemoryError: PermGen space

[Eric]

You appear to be encountering this problem in hosted mode.  If you are 
using a Sun (ahem I mean oracle) JVM you can use -XX:MaxPermSize to 
increase the perm gen space.

From your stack trace you also seem to be using jrebel 
(com.zeroturnaround.javarebel).  
This library may be introducing a bit of overhead in the perm gen space 
that helps you encounter this issue more easily.  Hot deploy is fun though.

[google-appengine] Re: Are key filters more efficient than ancestor queries?

[Eric Gustavson]

Hi,

In light of Google's pricing changes, I would like to re-open Blixt's 
original question, but instead of in terms of performance, I would like to 
know the answer in terms of price. This FAQ 
answerhttp://code.google.com/appengine/kb/postpreviewpricing.html#operations_charged_fordescribes
 how different datastore operations are priced.

Which is cheaper, a fetch by ancestor or via a ReferenceProperty?

Also, why should one avoid using the parent/ancestor relationship if they 
don't need transactions?

Let me know if my questions need clarifications.

Thanks!

--Eric

[appengine-java] Prospective search exception

[Eric]

Hi all, 

I've tried the new prospective search api today. It was alright to 
subscribe, unsubscribe, listSubscriptions, getSubscription. But when 
trying to list topics, below error message came out. I'm not sure 
whether it is a bug of the API or my problem. Is there anyone who 
knows something about this issue? Thanks.

[google-appengine] Does the URL Fetch service work with Wikipedia?

[Eric Thoma]

I am trying to make an application that would query Wikipedia, but when I 
try to use the URL Fetch service I run into an exception. The same code 
works for fetching both Google and Facebook. I am very inexperienced with 
Python web development and App Engine. Does anyone else run into the same 
problem with Wikipedia or can anyone confirm this?

Code Snippet

import os
import urllib2
from google.appengine.ext.webapp import template

class MainHandler(webapp.RequestHandler):
def get(self):
url = http://en.wikipedia.org/wiki/Do-support;
try:
  result = urllib2.urlopen(url)

[google-appengine] Re: The Amazing Story Of Appengine And The Two Orders Of Magnitude

[Eric Jang]

Fantastic post. Thanks for clarifying what an instance was!

On Sep 3, 12:32 pm, stevep prosse...@gmail.com wrote:
 I had spent most of the night wondering about task queue's apparent
 inefficiencies under Scheduler, and had planned to open a topic
 related to it, but then read Joshua's post.

 THIS point made by Joshua is THE HEART of the issue:'...it's a lot
 more trouble than just having a way to say to the scheduler, run
 these when you have an idle instance with nothing better to do, or
 DO NOT spin up an instance just to handle this task...'

 As Joshua suggests, there is likely a great deal of optimization
 within an instance obtainable by elegantly utilizing TQs. Scheduler
 today, however, seems quite inelegant (and unfortunately may remain
 that way because instance optimization is markedly revenue and profit
 negative for GAE).

 At this point, I would like to suggest that GAE employ a consultant
 who is an expert with systems modeling with iThink. The current
 opaqueness and complexity of Scheduler are an ideal situation for this
 type of systems analysis.**

 Please Google, can you give us some more help here.

 Thanks,
 stevep

 ** not at all affiliated with iThink, but have developed some
 financial analyses using iThink back in the day when I worked for HP.
 It really is a great tool for situations like this, and you guys will
 certainly find that there are some very experienced and capable
 consultants who will do great things for you without too much time
 needed from GAE personnel.

[google-appengine] Using A Java Application As Client to App Engine?

[Eric Atkinson]

For various reasons, I don't want to use a browser as my client. Why? 
Because, for example, although the Chrome browser can render my rather 
complex GWT client just fine, IE can't render it even if you install 
the Chrome Frame Plug-In, so I simply don't trust browsers as clients (too 
many uncontrollable unknowns). Consequently, instead of using a browser as 
client, I want to use a Java Application as client installed from GAE using 
JNLP (and I've got this part working on GAE after a bit trial and error on 
my part).  My question is: If I use a Java Application as client then the 
GWT (not GAE) documentation seems to be saying that I'll need to use com.
google.gwt.http.client.* to make my calls to the servleta using XML to pass 
data, and then converting the XML into JDO objects for the datastore. Does 
this sound right? I only ask because I don't want to do a lot of work trying 
this if GAE requires the client to be a browser (in which case I have to 
forgo using GAE because I hate browsers as clients).

You're right; it's my fault, I'm sorry. I don't know how a space got in

explained well (and explained quickly instead of in eight volumes). It's 
other app servers I've had a problem in the past, but not GAE.  Sorry.

[google-appengine] com.google.appengine.api.datastore.Key can not be found in source packages?!

[Eric Atkinson]

I get the follwing compile error -- com.google.appengine.api.datastore.Key 
can not be found in source packages. Check the inheritance chain from your 
module; it may not be inheriting a required module or a module may not be 
adding its source path entries properly -- with the below code snippet.

What's wrong with this code? Why can't the compiler 
see com.google.appengine.api.datastore.Key. I assume by inheritance chain 
it means the build path and that 
includes com.google.appengine.api.datastore.Key in the app eng SDK, so why 
am I getting the above compile error in the following code:

package com.sis.app.shared;

import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.PrimaryKey;
import com.google.appengine.api.datastore.Key;


@SuppressWarnings(serial)
@PersistenceCapable
public class ModelMember implements Serializable {
@PrimaryKey

This answer to this -- in the Eclispe IDE -- is to uncheck build

[google-appengine] Multiple Instances of the Same App

[Eric Kolotyluk]

I remember reading some policy that Google prohibits people people
from basically running the same app under different registration. I
gather one reason for this is so that people don't exploit the free
nature of apps, or so that Google is not replicating essentially the
same app everywhere. What ever the reason I don't want to violate
Google's policies.

We have an app we want to develop for our customers, but we
essentially want each customer to have their own instance of the app
for quotas and billing purposes. Basically, if our customers want the
service, they would pay Google directly, rather than us figuring out
who uses what and billing our customers. It would also make it easy
for our software to automatically create the customer's app on app
engine and keep it up-to-date.

An alternative design would be to have some way to invoke a central
app, but for service operations and quota have some way to bill things
to a specific account.

Does Google have any way to do this that does not violate the
policies?

The alternative for us is setting up a separate account for each
customer on either Amazon, Microsoft, or some other cloud, and
essentially giving each customer their own VM instance. There are pros
and cons to this, as there are with using the Google PAAS, and I am
trying to figure out what our best options are.

Cheers, Eric

 In the request handler where you're redirected to after login with

 look how you're checking for logged in user before redirecting to the

[google-appengine] Java Network Launching Protocol (JNLP) Support on App Engine?

[Eric Atkinson]

Does the Google App Engine, and related Web Server, support Java
Network Launching Protocol (JNLP)‎ for launching Java WebStart
Applications from my HTML home page?  GWT just isn't a sufficiently
sophisticated client platform, so I want to use a java application on
the front end to interact with the google app engine, but the app
engine would need to support JNLP to launch such a client. Is this
possible?

OK, I finally got around to trying this. Works like a charm. Thanks for 
such a simple fix to my problem

[google-appengine] Redirection problems after enabling OpenID

[Eric Kolotyluk]

After enabling the OpenID Federated Authentication on my app, when I
go to my app (via Firefox) I get the following

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for
this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to
accept cookies.

Chrome gives me more or less the same response, but way more verbose.

IE9 just chokes.

I've seen these kind of redirect problems before with Google Apps, and
after a while they just magically went away.

Should I just wait and try again another day, or just give up on
trying to get OpenID to work?

Cheers, Eric

[google-appengine] Understanding Security

[Eric Kolotyluk]

I've been playing around with security in my test app, and was hoping 
someone could confirm my understanding of things.

I have the following in my web.xml

  security-constraint
web-resource-collection
  web-resource-nameProtected Site/web-resource-name
  url-pattern/*/url-pattern
/web-resource-collection
auth-constraint
  role-name*/role-name
/auth-constraint
user-data-constraint
transport-guaranteeCONFIDENTIAL/transport-guarantee
/user-data-constraint
  /security-constraint

Which as far as I can tell forces everyone through the Google login no 
matter what URL they use. Is this correct?

I also have

  filter-mapping
filter-nameIdentityCheck/filter-name
url-pattern/*/url-pattern
  /filter-mapping

Which as far as I can tell only invokes the filter if a servlet is being 
invoked. It will not invoke a filter for any static content such as an HTML 
file. Is this correct?

I wanted to set up a second level of authentication to force people to 
register another identity with the site, and I thought I could do this with 
the filter by comparing their google ID with a of previously authenticated 
google IDs. That is, they would only have to go through second level 
authentication once, and then the app would automatically them through once 
they authenticated their Google ID.

But if filters only run when invoking a servlet, then static content cannot 
be protect this way because the second level of authentication will never 
get invoked.

Am I understanding this all correctly?

Is there any other mechanism I can use to implement this second level of 
authentication that does cover static content too?

Cheers, Eric

Re: [google-appengine] Understanding Security

[Eric Kolotyluk]

If I understand what you are saying, I could make every URL map to a 
servlet, and let the servlet return the specific static pages.


Or can I just put my folder of HTML into the resources section, and not 
have to write another servlet?


Cheers, Eric

You are correct.  Google stores and serves static files differently 
than Filters/Servlets/Resources.  I know of two alternatives:


1. Store your files as resources
2. Store static content in Datastore

[google-appengine] indexes stuck in Error state

[Eric Ka Ka Ng]

Hi Ikai,

Could you please help to remove 2 indexes in our app, which is being stuck
in the Error state? I have tried to vacuum the indexes, but always failed.
And this also prevents me to deploy new indexes too.

app id: gaewedev.appspot.com


I believe there were probably some problems when i'm trying to build that 2
indexes, as they involves entries having a high number of indexed terms
(index with list with long entries). So maybe after you help to remove the
indexes and then i try to build, the same problem could happen again. (from
my experience, if adding index to an empty data set, then populate the data
with the already built index should be ok; or when adding new item, always
add one by one) do you have tips / hints / guildeline to prevent running
into the same problem again? or could help us to re-build that 2 indexes?

Thanks in advanced.

Best Regards,
Eric Ng

[Eric Chow]

Hello,

How can I use ResourceBundle in GAE?
I can use it in local but failed in the cloud.

I want to get some message resources for using in the server side

Please help me.

[google-appengine] Policy on Tasteful Nudity

[Eric BP]

The program policies forbid Pornographic, obscene or excessively
profane content but oridinarily such a description would not include
nude art and other soft nudity without explicit sex.

Is nudity that would not be considered pornographic allowed?

Re: [google-appengine] Re: email sent by GAE would be regarded as spam for some email services

[Eric Ka Ka Ng]

me 2. Have integrated the SES service within our GAE apps.  work good and
solved our problems

sure it would be more nice if GAE can provide email service at the quality
level similar to the Amazon SES one (at least would not be classified as
SPAM), so we dont need to manage both . could we make this suggestion to GAE
team?

  Hi Eric,
 
  Have you looked at Amazon's Simple Email Service (SES)?
 
  http://aws.amazon.com/ses/
 
  Pretty much the same cost as sending email using GAE, except with SES you
  only get 2,000 free emails if you're sending email from an EC2 instance.
 
  I haven't used it myself but apparently they scan outgoing mail to make
 sure
  it meets ISP standards. This leads me to believe emails sent via SES
 would
  be less likely to be automatically marked as spam than on GAE, since
 SES's
  spam-sending-reputation would be lower than GAE's, due to their
  pre-filtering and rate-limiting.

   Hi Ernesto,
 
   thx for your suggestion! yes, i think it shall work.
 
   but in general if we can't ask all our users to add our email to their

 us
   prevent to be regarded as spam? all our subject, body etc. are nothing

Re: [google-appengine] Re: email sent by GAE would be regarded as spam for some email services

[Eric Ka Ka Ng]

Hi Ikai,

thx for your note. with this, we could better decide on which cases we would
like to send emails through GAE and which we would like to use other
external services.

and would it be more formally stated in any documents, or any guideline for
these considerations be documented? if i'm a new GAE user, i would just use
the email service straight forwardly without these considerations and
background information.

 I actually think we are moving away from this direction. For customers
 sending large volumes of email or who require delivery guarantees, we'll be
 encouraging the use of services that are specifically designed for this
