 second request: update the _session

 _session = FlexContext.getFlexSession().getAttribute(client);

 _session.setName(I am not null);

FlexContext.getFlexSession().setAttribute(client, _session);


 third request: print the name

[appengine-java] web.xml version=2.5 is not supported

2009-11-18 Thread Nacho Coloma
Hi all,

I have been trying to use the following web.xml elements in GAE:

jsp-config
jsp-property-group
url-pattern*.jsp/url-pattern
el-ignoredfalse/el-ignored
include-prelude/WEB-INF/taglibs.jspf/include-prelude

deferred-syntax-allowed-as-literaltrue/deferred-syntax-allowed-
as-literal

trim-directive-whitespacestrue/trim-directive-whitespaces
/jsp-property-group
/jsp-config

This instructs the JSP compiler to add some directives at the
beginning of all JSP pages:

* el-ignored: to be able to use ${...} at every page.
* include-prelude: to include a jsp fragment with tag libraries etc at
the beginning.
* deferred-syntax-allowed-as-literal: to ignore the use of #{...}
literals
* trim-directive-whitespaces: to trim the line feeds at the beginning
of each page

The thing is, this is only supported for web.xml 2.5 which I know is
supported by jetty but not by AppEngine. Anyway, I would expect it to
throw an exception instead of ignoring my XML start:

?xml version=1.0 encoding=UTF-8?
web-app xmlns=http://java.sun.com/xml/ns/javaee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation=http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd;
metadata-complete=true version=2.5

The thing is, I don't know if:

* It is planned to be supported by AppEngine at some point.
* I am missing the correct way of configuring this in GAE.
* Just nobody looked at it before.

Comments would be welcome. Best regards,

Nacho.

Re: [appengine-java] web.xml version=2.5 is not supported

2009-11-18 Thread Derek Berube
One of the issues that you are going to encounter is the mismatch between
the JSP API defined in GAE and the implementation of that API provided.  As
documented in bug
1506http://code.google.com/p/googleappengine/issues/detail?id=1506,
GAE includes the JSP 2.1 specification (found in the
geronimo-jsp_2.1_spec-1.0.1.jar); however, they provide the Apache Tomcat
Jasper classes from 5.0.28 which implements the 2.0 JSP specification.

If you want to use the 2.1 Unified Expression language, then you're going to
need to download the Unified Expression Language
https://uel.dev.java.net/ 1.1
API 
(el-api-1.1.jarhttp://download.java.net/maven/glassfish/javax/el/el-api/1.1/el-api-1.1.jar)
and Implementation
(el-impl-1.1jarhttp://download.java.net/maven/glassfish/org/glassfish/web/el-impl/1.1/el-impl-1.1.jar)
files and place them in the WEB-INF/lib directory of your web application.
Once that is done, modify your web.xml with the following snippet of code:

!-- GAE Bug 1506 JSP 2.1 API but 2.0 Implementation --
context-param
  param-namecom.sun.faces.expressionFactory/param-name
  param-valuecom.sun.el.ExpressionFactoryImpl/param-value
/context-param

This should make the Unified EL available to your web application.

Re: [appengine-java] Configuring JSF 2.0 to run on Google App Engine

Denden,

What does your web.xml look like?  What libraries to you have in the
WEB-INF/lib directory of your web application?  Are you trying to use a
component library such as ADF, RichFaces, or ICEFaces?

I have a working version of the JSF2 framework running on GAE posted at

I'm seeing the same thing here. All of a sudden I can't deploy to the

only thing that may have an effect is that I had someone else on my

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

 Ilya,

 Are you looking to persist objects for a lifetime of a session, or are you
 looking to minimize the logic you are using in your JSPs?
 As a general design principle, we recommend that you minimize usage of
 session scope. Variables bound to session scope are serialized and stored to
 distributed memory, and as a result, it will work best if you use it to pass
 around small, simple, immutable objects.

 If you're looking to pass a variable to a view, Java Servlets have a concept
 of page scope as well as session scope. You don't need to store a variable
 in session scope if you just want to dispatch the request to a JSP. For
 instance, you can define a Servlet that looks like this:

 public class MyServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse
 response) throws ServletException, IOException {
      String myVar = this is a string that will be passed to the JSP;
      request.setAttribute(myVar, myVar);
      RequestDispatcher dispatcher =
 request.getRequestDispatcher(/WEB-INF/my.jsp);

      dispatcher.forward(request, response);

    }

 }

 In my.jsp, you can now refer to this variable:

 %@ page isELIgnored=false %
 body
   h1${myVar}/h1
 /body

[appengine-java] Re: Configuring JSF 2.0 to run on Google App Engine

2009-11-18 Thread andyz
Denden,
I have same problem.
the root cause is the version of Mojarra2.0.0
if you open jsf-impl.jar,
there is a file: META/taglib/ui.taglib.xml
notice the tag remove
tag-nameremove/tag-name
handler-class/handler-class
handler-class is NOT defined.
this would cause a problem and throw NPE.

change the jsf2 libraries from mojarra 2.0.1

everything is OK.

[appengine-java] Re: Configuring JSF 2.0 to run on Google App Engine

2009-11-18 Thread andyz
Denden,
I have the same problem as you.
I found the root cause.
The library jsf-impl.jar you(and I ) is in downloaded zip file:
mojarra-2.0.0-FCS-binary.zip.
if you open jsf-impl.jar, there is a file: META-INF/taglib/
ui.taglib.xml.
at the end of this file:
tag-nameremove/tag-name
handler-class/handler-class
 handler-class is NOT defined,this causes a problem and throw NPE

Once I replaced with mojarra-2.0.1,
then It's OK.

[appengine-java] Re: NullPointer on key

2009-11-18 Thread IlyaE
Running into another issue. So i'm detaching my object and passing it
along in a session.

I'm now getting this error WARNING:
javax.jdo.JDODetachedFieldAccessException: You have just attempted to
access field contactInfo yet this field was not detached when you
detached the object. Either dont access this field, or detach it when
detaching the object.

my contactInfo is an embedded persistent object in the object i am
detaching.
@Embedded
@Persistent
private ContactInfo contactInfo;

If i make contactInfo @Persistent(defaultFetchGroup=true) then i get
this error.
WARNING: The datastore does not support joins and therefore cannot
honor requests to place child objects in the default fetch group.  The
field will be fetched lazily on first access.  You can modify this
warning by setting the datanucleus.appengine.ignorableMetaDataBehavior
property in your config.  A value of NONE will silence the warning.  A
value of ERROR will turn the warning into an exception.

What is the correct way of making sure this embedded object is also
detached when i save it to the session?

 What state is the object in when you access its field ? (Call
 JDOHelper.getObjectState(obj)).
 Since no transaction boundaries or PM lifecycle is presented, it's
 hard to guess. If you leave the object to become transient then it
 will likely have its field values nulled when leaving the transaction/
 PM (unless you bothered setting javax.jdo.option.RetainValues)

Hi All,

I created a JDO class, which had some attributes, and I created some

Then I added a new attribute in the JDO class, and then set value to
it and persisted it as usual when I executed CRUD operations. The
problem is that I cannot retrieve the value of the new attribute in
program, the value is always null. But when I check the value in
Datastore - Data Viewer, the value is correct. So i'm wondering
why it cannot be retrieved in application. Is there some cache
mechanism?

  Ilya,
 
  Are you looking to persist objects for a lifetime of a session, or are
 you
  looking to minimize the logic you are using in your JSPs?
  As a general design principle, we recommend that you minimize usage of
  session scope. Variables bound to session scope are serialized and stored
 to
  distributed memory, and as a result, it will work best if you use it to
 pass
  around small, simple, immutable objects.
 
  If you're looking to pass a variable to a view, Java Servlets have a
 concept
  of page scope as well as session scope. You don't need to store a
 variable
  in session scope if you just want to dispatch the request to a JSP. For
  instance, you can define a Servlet that looks like this:
 
  public class MyServlet extends HttpServlet {
 
 protected void doGet(HttpServletRequest request, HttpServletResponse
  response) throws ServletException, IOException {
   String myVar = this is a string that will be passed to the JSP;
   request.setAttribute(myVar, myVar);
   RequestDispatcher dispatcher =
  request.getRequestDispatcher(/WEB-INF/my.jsp);
 
   dispatcher.forward(request, response);
 
 }
 
  }
 
  In my.jsp, you can now refer to this variable:
 
  %@ page isELIgnored=false %
  body
h1${myVar}/h1
  /body

2009-11-18 Thread Matthew Blain
Hi everyone,
Thanks for the response so far--we'll be getting back to you over the next
few days.
I'd like to point out an existing feature which will be helpful to many of
you: --dump and --restore. This will download or upload all of
the entities for a particular Kind and save them in a local sqlite database.
It's useful for general backup (e.g. a weekly backup), and also useful for
moving data across applications, such as between your app running on the
dev_appserver and on App Engine, or to load a staging instance with a known
set of test data.

You can find more information here:
http://code.google.com/appengine/docs/python/tools/uploadingdata.html#Downloading_and_Uploading_All_Data

Also, for Java developers, there is a remote API handler available; adding
following to your web xml file should work (disclaimer: I have not yet
personally tested this.)

 Two specific issues we're addressing at this time are:

That's good information to know. We are not using Sun's JavaMail

There's one last thing you may want to try:

http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/mail/package-summary.html

The above page documents the Low-Level API. Try creating an email object via
that API, setting the Content-ID of the attachment and the HTML tag to point
to the cid. You're already doing that in the example you sent using

2009-11-18 Thread mably
I haven't found a way to set a Content-ID header on a mimebodypart/

is quite rudimentary (only filename and data).

May be some part of the low level API are still undocumented ?

 If not, I'll open an issue.

Matt,

There probably isn't anything you'll be able to do in the meantime. You may
not see this when deployed since we are not using a different servlet engine
in production. Can you go ahead and open an issue here for us to upgrade our
SDK's version of Jetty?

http://code.google.com/p/googleappengine/issues/list?can=2q=jetty

It's something we'd eventually want to do anyway, and getting it into the
issue tracker will mean it's on our radar.

 Ikai,

 Reading all of the Jetty bug report you found, I see that it is
 possible to configure the size of the header buffer used by Jetty.
 This is done in the jetty.xml file.
 I don't see that file within my GAE project.
 I see appengine-web.xml.

 Does GAE expose/use jetty.xml or some equivalent?
 If so, where would I find it?

 If I can configure the Jetty that is bundled with GAE Dev server, then
 that would solve my problem.

 Thanks.

  Thanks Ikai for responding and for finding that Jetty bug report.
  It is marked as fixed in Jetty 6.1.11.
  Do you know if that fix is in the version of Jetty that is bundled

  I can't store that data in the session because the data being stored
  in the cookies is not being placed there by me.
  It is being placed there by the Application Server software I'm using
  which is running on top of the GAE.
  Specifically it is being placed there by OpenBD Google which is a
  version of BlueDragon (a CFML Engine) ported to run on GAE. BlueDragon
  is the Application Server that powers MySpace.
 
  http://www.openbluedragon.org/
 
  http://wiki.openbluedragon.org/wiki/index.php/Category:GoogleAppEngine
 
  Storing such data in cookies is a requirement/feature of the CFML
  Engine. That is how Adobe's ColdFusion CFML Engine functions. It is
  jjust name/value pair data (String data)... variable defined to be in
  something called the client scope (in CFML speak).
  BD may be configured to store client scoped variables in either
  cookies or a database... so using the database option would work
  around this problem but it still seems like something that should be
  fixed for GAE.
 
  BlueDragon runs on top of various platforms:
   Microsoft .NET framework
   WebSphere
   Weblogic
   ServletExec
 
  and behind commercial grade webservers (IIS, and Apache) and does not
  exhibit this problem in any of those environments... only with Jetty.

  This looks like it may be a JeTTy issue:

  That being said, I'm curious as to what data you are storing in the
 cookie.
  Less than 1.5% of sites pass cookies larger than 1501 bytes, and there
 are
  performance implications for passing large amounts of cookies:
  http://yuiblog.com/blog/2007/03/01/performance-research-part-3
 
   Is this data you can store in the session instead?

  The behavior I see is that the browser receives what seems to be a

  halted when the exception occured). If I configure my browser to send
  its requests through a diagnostic proxy tool, I can see that the
  request headers being sent are about 5k total. But the response takes
  2-3 minutes to come. Once it does, the proxy tool shows me only
  response headers (no response body):

  which I suppose explains why the browser renders it as an empty
  response.

 edit an instance of M they are presented with an edit page that:
 1) has a list of checkboxes for each category
 2) each category that belongs to the instance of M being edited is
 preselected (prechecked)

 Since django templates aren't very powerful, I can't do the comparison
 of the set of all categories vs the set of categories belonging to M
 within the template (and I guess I shouldn't).  Can someone point me
 to the correct pattern for doing this?

 Thanks,

[google-appengine] Cron job schedule time reset when uploading new version

2009-11-18 Thread djidjadji
I have a simple cron job that needs to run every X hours

--- cron.yaml ---
cron:
- description: Hourly Check
  url: /jobs/check
  schedule: every 1 hours
--

If I upload a new version of the app the schedule time of the cron job
is reset. I haven't changed cron.yaml.
The dashboard cron jobs page shows hasn't run yet after an upload.

Why is the schedule time reset on upload of application when the cron
job is not changed?

Why is the cron job not scheduled/called immediately (or 1 minute)
after the upload, if the reset is needed?
Then the job would be called a few times to much but at least it gets called.

If you have an every 3 hours and you do a few uploads in a day the
cron job is hardly ever called.

Re: [google-appengine] Re: Increasing task queue quotas

2009-11-18 Thread djidjadji
Is your processing not possible with the deferred module added in 1.2.5

http://code.google.com/appengine/articles/deferred.html

If you launch many tasks to process the uploads you waste a lot of CPU
retrieving the data needed. With the deferred method you run for about
30 sec, then store the state and schedule to get called again. You can
setup multiple deferred tasks to process 1 upload by using parameters
of the function that deferred calls.

2009/11/18 Julian Namaro namarojul...@gmail.com:
 I'm not sure about what you want to do but just a thought: have you
 considered Amazon Elastic MapReduce ?
 It's sure doable with task queues but you're likely to encounter
 various limitation problems as you cite.

 Hi,

 I'm evaluating GAE suitability for one of my clients.  It is a B2B app
 with very low organic web traffic.  However, users upload lists of
 data that need to be processed in the background.

 In the absence of native MapReduce support, my plan is to use task
 queues.  But to meet the performance needs of this application, I need
 to burst to relatively high levels of concurrency.

 My question is about the discrepancy in the GAE quotas for inbound web
 traffic vs. task queues.

 Inbound web traffic can burst to: 500 qps
 Task queues burst to: 20 qps

 In my mind, the total concurrency that GAE would provide an app is
 equal to:
 inbound qps + task queue qps + cron qps.

 Given that task queues are implemented as web request handlers, I see
 little infrastructural reason to distinguish between task queue and
 inbound traffic.

 Is it possible to request a task queue quota increase to 500 qps?  If
 not is there a technical reason for this?

 thanks

[google-appengine] Why not implement a Django database backend for App Engine?

2009-11-18 Thread frankabel
Hi all,

I'm newbie in this App Engine. As far I know, lot of Django app
portability get solved if someone implement a  Django database backend
for App Engine. Even I read Once queryset-refactor lands in trunk, it
might also be possible to write a database backend for App Engine that
would allow any app to run properly.  at 
http://martyalchin.com/2008/apr/8/appengine/

Somebody can explain me why isn't implemented yet such database
backend? I, mean is a big deal? What are the main problems that ones
must address to write such backend? If the backend exist, porting
Django app will be more easy that using Google App Engine Helper for
Django?

Cheers

weird because the template works but sometimes I see that error, so
it's not about that it doesnt exist. I have like 40 request per second

Re: [google-appengine] Cron job syntax

2009-11-18 Thread Eli Jones
Here's the fun way!

Figure out a way to represent the sequence of hours you need it to run... n0
= 6, n1 = n0 + 1, n2 = n1 + 1,  n3 = n2 + 1, n4 = n3 + 1, n5 = n4 + 3, n6 =
n5 + 4

Have a cron job start it off at 6am... Then have the code set a taskqueue to
call itself.. Setting k = k+1 as a parameter each time until it gets to k =
6.

I think u could use a = 1 + floor(k/5)*(k-3)

So.. You'd have:
n[0] = 6 and n[k] = k + a

Which.. if you start at 6AM, will then run at 7,8,9,10,13,17

Thus.. At the end of the k-th run.. You just fire off a taskqueu to call the
url again with delay = a and params = {'k' : k+1}

When the task url is sent the put request.. it checks if k6 or whatever..
if it is.. then the rest of the task runs.

kind of cheesy.. but fun to think about. :)

[google-appengine] Searching the datastore

2009-11-18 Thread Barakat
Hi All,

I want to have a search box in my page so the user can search for name
in an address book

for example i expect the user to write any words he wants in the box
for search for example
Mike Laurance California

If such words written and I want to search with it in my data store
that has a property for name, address, phone number and other
properties, because I don't know what the user will write in the
search box, I have to loop with the written words to do queries on all
kind of properties i have, then do like intersection between these
queries I got from that search.

This the way I am thinking in to implement such kind of search, but I
see this not an efficient one because with the number of inputs to the
search increase, the queries is increase, and if the datastore has
huge number of entries, it will become a mess.

Also I didn't find an function to intersect queries, it should be done
with loops which another mess.

Is there any way to do this search with an efficient way even if it is
complex.

I don't have any knowledge about search engines and techniques, so if
there any article or book good to give me a start so I can get the
basics for that?

Thanks in  Advance

[google-appengine] Re: appcfg.py upload_data failing early

2009-11-18 Thread Lloyd
To follow up.  I cross posted on StackOverflow

Brit: Do you get any more information when you add --noisy ? Are you
logged in before you run above line ?

Me: Thanks, I didn't know about that flag. The odd thing is that it
seems to not make any difference on the WinXP machine that I was
working on. To make it odder, the flag, and the upload worked just
fine on my Windows 7 lappy. This helped me track down the issue with
the install on my WinXP machine.

 If such words written and I want to search with it in my data store
 that has a property for name, address, phone number and other
 properties, because I don't know what the user will write in the
 search box, I have to loop with the written words to do queries on all
 kind of properties i have, then do like intersection between these
 queries I got from that search.

 This the way I am thinking in to implement such kind of search, but I
 see this not an efficient one because with the number of inputs to the
 search increase, the queries is increase, and if the datastore has
 huge number of entries, it will become a mess.

 Also I didn't find an function to intersect queries, it should be done
 with loops which another mess.

 Is there any way to do this search with an efficient way even if it is
 complex.

 I don't have any knowledge about search engines and techniques, so if
 there any article or book good to give me a start so I can get the
 basics for that?

[google-appengine] Re: weird TemplateDoesNotExist error

2009-11-18 Thread Jason C
Are you using Django 1.0? There is an initialization problem with
Django 1.0. If a DeadlineExeecedError occurs while a new instance is
spinning-up, it can leave Django 1.0 in a partially initialized state
and these kind of errors will continue to stream out until the
instance is recycled.

We've tried moving to Django 1.1 which apparently corrects this
problem. So far, so good.

[google-appengine] Re: Limit on image size very low

2009-11-18 Thread Cynthia Kurtz
Another issue is, the 1MB limit is incompatible with audio and video

needed, it's everything. I had planned to have people be able to
collect stories in audio format (say from old folks) and upload them
to my site (Rakontu) but given the 1MB limit that's pretty much out of
the question. That and the Timeouts and other gotchas make it hard to
create anything that approximates real social media on GAE. :( But
here's hoping it grows up over time. Moore's law is in our favor

[google-appengine] Re: Looking for Bulk Loader beta testers

2009-11-18 Thread Matthew Blain
Hi everyone,
Thanks for the response so far--we'll be getting back to you over the next
few days.
I'd like to point out an existing feature which will be helpful to many of
you: --dump and --restore. This will download or upload all of
the entities for a particular Kind and save them in a local sqlite database.
It's useful for general backup (e.g. a weekly backup), and also useful for
moving data across applications, such as between your app running on the
dev_appserver and on App Engine, or to load a staging instance with a known

 Two specific issues we're addressing at this time are:

[google-appengine] Re: Increasing task queue quotas

2009-11-18 Thread James Cooper
Hi,

My primary concern is throughput, not cost.  I would be happy to pay
more to gain higher concurrency and higher throughput.

If a customer uploads a list with 100,000 items to process, I would
like to burst to some upper limit of concurrency (higher than 20 qps
at least) and process the list as quickly as possible.

This seems to be something GAE could provide if the concurrency limits
were raised.  My question is whether Google would allow a customer to
request a quota increase for task queue concurrency in situations like
this, or whether that's forbidden across the board for some reason.

Anyone from Google who can help answer this?

thanks,

 Is your processing not possible with the deferred module added in 1.2.5

 http://code.google.com/appengine/articles/deferred.html

 If you launch many tasks to process the uploads you waste a lot of CPU
 retrieving the data needed. With the deferred method you run for about
 30 sec, then store the state and schedule to get called again. You can
 setup multiple deferred tasks to process 1 upload by using parameters
 of the function that deferred calls.

[google-appengine] Getting Strange Error From Cron Job

2009-11-18 Thread Kevin
I am attempting to implement an application that performs some
occasional web crawling as a component of its day-to-day
functionality.
The web crawling code can be executed from a jsp file.  When I test it
on my computer by accessing the jsp file, it performs its desired
function nicely, as expected.
So I decided to go try it on the app engine, and if I run it by
accessing the .jsp file, I get a HardDeadlineExceededError, which I am
told occurs when the request takes longer than 30 seconds, which is
understandable.
However, when I try to execute it as a cron job, every time it runs,
it ends after about 5 seconds, with a different exception:
java.lang.ClassCastException: java.lang.ArrayIndexOutOfBoundsException
cannot be cast to javax.servlet.ServletException
...and the stack trace doesn't reference any of my code at all, which
is making this difficult to debug.  Does anyone have a clue what might
be causing something like this?

I'd reproduce and track exactly where, either in engine or app, find
the iteration or recursion accessing the Array and we know more. Array
or ArrayList is the best structure and trying to access element

[google-appengine] datastore glitch/corruption?

2009-11-18 Thread ussuri
I'm experiencing weird data corruption issues that seem to be caused
by a glitch in the datastore. There is a chance that there is a bug in
my code, of course, but I have spent hours looking for holes and I see
none.

Basically, I have an entity (table) with several content fields and
two tracking fields. One is a simple timestamp that is auto updated
(auto_now = True). The other tracking field stores the session ID of
the last session that updated the entity. There are only four methods
that update the entity, and all set the session ID properly.

Situation: sometimes entities get one of their content fields (of the
TextProperty type) populated with weird data, probably (this is a
guess) with data from other records in the same 'table'. What's more,
it appears that this happens on read-only operations. For example, I
read today about 100 records, and most of them had this field
corrupted. ALL OF THE CORRUPTED RECORDS  had the 'modified' field
(auto_now timestamp) set to the time when I was reading them, while
all of them had last_session_id set to a session that happened a month
ago.

I've read about a gmail glitch that resulted in some users seeing
emails of other users, and this seems to be a similar kind of bug.

Am I imagining things, and the datastore is 100% reliable, or is the
scenario I am describing potentially possible?

Thanks,
MG
