[appengine-java] Strange behavior by " App Engine Eclipse Plugin"

[cp]

I am working on personal project in my eclipse environment. Today i decided 
to deploy the application version (4th version).
Strange thing is happening.

1. When i click on icon "Deploy app engine project". It is probably opening 
firefox or ie browser window instead of usual eclipse dialog box.
Browser window says below:
  *"A third party service is requesting permission to access your Google 
Account. *
In order to authorize a third party service to access your account, you must 
sign in."

Once i enter the user pass then it says:

Your  browser's cookie functionality is turned off. Please turn it on.

[appengine-java] UserService--Fails to get the right "current user"

[July]

Hi All:
 I met a strange behavior when using UserService, i'm a Google Apps 
user.

1. I have two Google apps domains, first login the first domain by entering 
the gmail of my domain.
2. Login to my own application Using OpenID which deployed at GAE, then the 
userService.getCurrentUser() is my account in first domain.
3. Click the upper right "logout" link to logout my first domain, then login 
using my second domain email address
4. Now try to access my GAE project, and found userService.getCurrentUser() 
is still the first domain's email. I think it should be the email of second 
domain.

Any ideas about this? thanks very much.

[appengine-java] Google App Engine + Java Applet

[SKP]

Hi

I have been trying to do Encryption /Decryption (using javax.crypto)
on browser side i.e. using javascript. Data is stored in GAE's
datastore.  I created a java applet that can encrypt/decrypt to use
javax.crypto. But now i see that google app engine doesnt support
java.applet.Applet . Is there any work around or anyway I can go about
browser side encryption /decryption?

Thanks

[appengine-java] Backend + push task queue, does it work?

[de Witte]

Hello,

Looking for any tips to get this working.


try {
Queue queue = QueueFactory.getQueue("test");
TaskOptions options = 
TaskOptions.Builder.withUrl("/test/task/worker");

options = options.param(TestTask.task, params);
options = options.header("Host", 
BackendServiceFactory.getBackendService().getBackendAddress("testtask", 1));

queue.add(options);
}
catch(Exception exc) {
log.log(Level.SEVERE, "queue", exc);
return false;
}

I have setup the backend.xml:


  
B2
1
1

  false
  true

  


Didn't make any other changes.

The dashboard shows that the backend is active, but the doPost method of the 
TaskServlet is never being called.

Any ideas?

[appengine-java] Local Server and local_db.bin

[pavb]

Hello

I have a problem to initiate my local datastore with test data.
I have created a unit test to populate my local datastore and create
the file local_db.bin. (ApplicationId and versionId correctly set)
Everything looks ok. But when I use this binary file with the local
server in the war/WEB-INF/appengine-generated I can not browse my
entities. Nothing is displayed with the admin console.
I can create entities directly from my application and these ones are
visible.

Could you help me please?

Thanks

Re: [appengine-java] DeadlineExceededException on Jetty session loading

[Francois Masurel]

Hi Don,

I was just wondering : could these buggy DeadlineExceededExceptions cause a 
memory leak ?

I've seen my instance take up to 134MB just running 2 simple datastore 
queries (DeadlineExceededException) every minute.

Do you know when will the next SDK version be released ?

BTW, it looks like I get these deadline exceptions every 500 datastore api 
calls, quite far from the every 3000 announced. 

Thanx for your help.

Francois

[appengine-java] Re: Upload blob never calls success path

[Daniel Florey]

Hi,
thanks a lot for the info.
I did not even upload to App Engine, just using the development server. So I 
guess there is just the default version?

My servlet is never called, so I cannot even send a redirect yet.
I just end up with an entry in the  __BlobUploadSession__ table and I assume 
that I may need to turn on some flags to call my success path after upload?

Is there a way to turn on debug logging for the core services?

Thanks!

Daniel

[appengine-java] Is possible to create a datastore index programmatically

[Pablo Salgado]

Hello,

I'm storing schema-less data (the columns are not fixed, they are
created at application runtime). I need to make some index for those
columns to sort and filter rows by some of those columns.
Is it possible to create a datastore index programmatically at
application runtime?
Thank you in advance,

[appengine-java] Re: Upload blob never calls success path

[Juan Hernandez]

Hi,

I just posted a similar question to yours:
http://groups.google.com/group/google-appengine-java/browse_thread/thread/b6b540e20b3730ca

My successUrl is being called but it only works if I'm using the
default version of the app. Put a System.out or a logger statement in
your success page and check the logs on the AppEngine console to see
if it goes thru your default version.

Do you get back any error in your browser? error 500 or some other
error?

You can only do a redirect in the success page (3xx return codes), you
cannot return any content, did you know that??

Hope that helps
Juan

[appengine-java] Uploading files not working with the BlobstoreService when the app version is not the default one

[Juan Hernandez]

Hi,

I'm using the Blobstore service to upload files in my webapp and found
that that service doesn't work properly when I have multiple versions
of my app.

The problem is that my "successUrl", the one passed in the
createUploadUrl(...) method, is not being called after the form is
submitted ... well the URL is called but the one in the default
version of the app.
If I'm testing version 2 of the app and the default version is 1 
the upload ends calling the "successUrl" but in version 1 of the
app !!??

Has anybody experienced that issue?

I have tried different types of URLs when calling the
createUploadUrl(...) just in case the one I was using was wrong, but
haven't had any luck ...

I tried absolute to the site URLs (eg. /blobstore/uploaded.jsp),
relative URLs (eg. uploaded.jsp), absolute URLs (http://
2.appname.appspot.com/blobstore/uploaded.jsp) and none of them work
with any other version than the default one.

Looking into the logs it calls the uploaded.jsp on the default version
of the app when using the first type of URL (/blobstore/uploaded.jsp).

This is a sample code I'm using for the upload form:

<%@ page import="com.google.appengine.api.blobstore.BlobstoreService"
%>
<%@ page
import="com.google.appengine.api.blobstore.BlobstoreServiceFactory" %>
<%
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
%>

" method="post" enctype="multipart/form-data">





Thanks
Juan

[appengine-java] Upload blob never calls success path

[Daniel Florey]

I guess I'm just dumb, but please help me anyway ;-)
I've just tried to upload a blob into the blobstore. When I upload the blobs 
I can see an entry for each upload in the __BlobUploadSession__ table.
I also can see in there that the success path is properly set, but my mapped 
servlet is never called. (I can call it from the browser though, so it seems 
to be mapped correctly).

Do I have to enable some option on the devserver so that the success path 
servlet will be called once the upload is complete?

Thanks for any hints,

Daniel
