[appengine-java] Re: Robot copy to clipboard

[m seleron]

Hi,

I think that I should evade using the one not explained in the
whitelist.

Please refer to this link.
http://code.google.com/intl/us/appengine/docs/java/jrewhitelist.html

I think it's possible to request the following links helpful.
http://groups.google.com/group/google-appengine-java/browse_thread/thread/8a64ae454f758435/b0484413bcedc38c?lnk=gst&q=awt#b0484413bcedc38c

Please confirm.
thanks.

Re: [appengine-java] Newbie HttpSession questions

[Jess Evans]

The memcache is volatile without a well defined contract for expiration, so
it alone is not sufficient to support session behavior.  A memcached entity
is more like a SoftReference in contract.  Well a globally shared
SoftReference with, presumably,  some cross JVM network serialization
overhead (that last part being a guess).

No problem.  And yeah, I used the word "bug" loosely -- I agree that this is
just missing functionality.

Ah okay... now I got what you mean by the year bug. This is for sure
something I did not think about and what lead to my confusion. Thanks
for pointing that out. imho i do not think that it is really a bug; it
is simply too easy to be confused, a YEAR_OF_THE_WEEK would be cool as
stated by bmcardoso.


But still - one question remains: Why is the "ww" different in the US
(Don's machine and App Engine) (01) compared to Germany (53). Well. I
played around with the code, and one thing I forgot to set initially
was the Locale of the SimpleDateFormat(pattern, Locale). Setting it to
Locale.US returns week 01; setting it to Locale.GERMAN returns week
53. Bingo.

And the answer lies in the fact that getFirstDayOfWeek() is in
Locale.US sunday, in Locale.GERMAN monday. Together with the way how
week is calculated we have a different week depending if you are in
the US or in Europe. Still really strange.


Summing up: Not at all a bug in app engine, but I would never ever use
week in a critical international environment...


Thanks Don... that really helped me a lot :)

[appengine-java] Using UserService credentials with a SpreadsheetService

[zackmac]

In my GAE/J web application, users authenticate via their google
account.  I check to see they've signed into google via this code in
my jsp:

UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user == null)
response.sendRedirect("/index.jsp");

Is there anyway to use the user object above to query for that user's
spreadsheets?  I'm thinking that it would involve using
user.getAuthDomain() but not sure if I'm right here.  For instance,
would this work?...  service.setAuthSubToken(user.getAuthDomain());

Re: [appengine-java] Entity copy/duplication/replication

[Ikai L (Google)]

You have a couple of options here:

- Bulk export/import using the Python bulkloader
- Create an administrative action that invokes the task queue

App Engine datastore is not backed by SQL, so you don't have a lot of the
convenience statements you would otherwise have. You'll have to solve the
problem programmatically.

Re: [appengine-java] How to architect the following persistence problem

[Ikai L (Google)]

Is there a reason you want to avoid hard coding roles? I can certainly
understand from an OO purists perspective why that can leave a nasty
aftertaste, but if you have a finite set of roles, it isn't the worst thing
in the world. In fact, it may simplify your overall design. To me, join
classes when there are only a very small set of possible roles feel
unnecessary.

>From a datastore perspective, you aren't creating columns. You are creating
a typeless entity that is stored in key-value storage, with only attributes
containing values being indexed. That is: if a Partner has a Teacher and
Student but no Employee, only those Teacher and Student values are indexed.

As far as denormalization is concerned, App Engine heavily favors small
requests over larger requests that require more calculations at request
time. What this means is that you are encouraged to calculate denormalized
value at write time such that reads can happen very quickly. It seems like
denormalization can work very well in your situation, but this is a decision
you'll have to make based on the needs of your application.

Re: [appengine-java] Wrong calculation of week in App Engine

[Don Schwarz]

The bug I referenced is definitely still present up to at least Java
1.6.0_10 .  I get "200901" when I run this code on my local Sun Java
1.6.0_10 JDK with a timezone of CST for 1262000152901L.

The bug is that it's returning a value of "200901" instead of "201001" for
time points that occur in 2009 but are in the "first week of 2010", which is
defined as:

"Week 1 for a year is the earliest seven day period starting on
getFirstDayOfWeek() that contains at least getMinimalDaysInFirstWeek() days
from that year."

This blog post has a better description of the JRE bug:

Re: [appengine-java] JavaMail: AccessControlException warning

[Ikai L (Google)]

No, this is a harmless exception that seems to fire off when an app is
loaded from a cold start. There's some chatter about this here:

[appengine-java] Re: Datastore W/O JDO or JPA??

[Iqbal Yusuf Dipu]

@jd and @ vbart thanks for your input. I have also found Objectify, it
feels RESTful.

http://code.google.com/p/objectify-appengine/

People please post more projects (if  there are more) so that we can
create a list of JDO/JPA alternatives here.

Thanks.

Re: [appengine-java] Wrong calculation of week in App Engine

Hi Don,


thanks for the superfast reply. I tried it again setting the locale
and the timezone explicitly (and also using explicitly the
GregorianCalendar).

==snippp
Calendar calendar = GregorianCalendar.getInstance(
TimeZone.getTimeZone("MEZ"), Locale.GERMAN);
calendar.setTimeInMillis(millisecs);
DateFormat formatter = new SimpleDateFormat("ww");

return formatter.format(calendar.getTime());

== snapp

however the error is still there. Using the timestamp of now
(1262000152901L) my local machine tells me:
"200953"  what is correct, but App Engine returns the wrong "200901".

Hmm. What puzzles me is why my local machine can calculate the "ww".
Therefore I am still not too sure if the bug you mentioned (4267450)
from sun still applies to my SDK version 1.6 - because my 1.6 series
can calculate the week without any problems.

The next question then is: What SDK is the App Engine using? I bet
it's not the SDK from Sun, but Open SDK or a derivate. And if that's
the case this might be a bug...


I think I am going to implement the "ww" myself to circumvent the App
Engine behavior and file a bug... Not nice, but I need the
functionality...

[appengine-java] 401 error

[Max]

I am developing bulk uploader.
I delete all objects from datastore and upload data then delete and
upload again.

Recently I reached limit.

So I was invited to join new "paid" application created on another
google account.

I uploaded my project but my servlet returns 405 (Method Not Allowed)
error when I try to upload data.

Data is uploaded throw POST method.

I just changed Application ID it is very strange to me and I do not
have any idea how to debug it.

Re: [appengine-java] Re: GAE roadmap for 2010

[Ikai L (Google)]

Not at all. As Phillipe mentions, voting on issues helps us a lot when
prioritizing fixes. As far as "big targets" go, we'll announce them and
update the roadmap when it becomes clear what they are. This'll likely
happen sometime in Q1 2010. There are a few things which we are always
looking at but aren't listed because they are very long term goals that
we'll be taking incremental steps towards:

- Improving cold startup time
- Datastore performance
- Improving reporting transparency

There are a lot of projects that may not be listed on the roadmap but will
be released in alpha form. A good example is AppStats:
https://sites.google.com/site/appengineappstats. We'll try to keep the
groups as up to date as we can.

Re: [appengine-java] JDO Mapping issue : A parent cannot be established or changed once an object has been persisted.

[Ikai L (Google)]

Parent relationships cannot be established after an object has been saved
because the parent Key information is saved in the Child Key as a prefix. If
an Artist is the parent of a Song, your Song key will looking something like
this unencoded (this is just a pseudo-key):

Artist(Madonna):Song(Papa Don't Preach):

If you save the Song object before the artist object, the Song already has
the Key:

Song(Papa Don't Preach)

This cannot be changed. Rather than a parent-child relationship, you may be
better off designing your objects to contain Keys of related objects. That
is, your Song object should have a Key referencing the Artist. This'll allow
you to save in arbitrary orders, though you may have to revisit your entity
group setup if you need transactional writes.

Re: [appengine-java] Re: JDO Query for properties with null values

You should be able to query for a null value, but you will not be able to
query for an empty value. What is the query you are issuing? What is this
returning?

Re: [appengine-java] 1K results query limit removed?

[Don Schwarz]

You can get more than 1K entities as long as you iterate over them.  You
just can't fetch more than 1K entities in a single batch (e.g. via
PreparedQuery.asList()).

[appengine-java] Re: What's the right way to use PersistenceManager?

[patr...@kodova.com]

I playing around with GWT RPC & App Engine and was wondering the same
thing today and I ended up using a ThreadLocal.Also I am going to do
some refactoring it to make it work with dependency injection so I can
reuse it in the future.

Pros:
 * I have one PersistenceManager per RPC request.
 * Less code on every method to handle exceptions and closing
connections
 * Entity objets being passed around between methods are not detached.

Cons:
 * Increases runtime exceptions if you forget to initiate the
PersistenceManager
 * Currently not very friendly for unit testing of your RPC calls but
can be fixed.

PMF.java
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper
.getPersistenceManagerFactory("transactions-optional");
private static final ThreadLocal pmLocal = new
ThreadLocal();

private PMF() {
}

public static PersistenceManager initPersistenceManager() {

pmLocal.set(getPersistenceManagerFactory().getPersistenceManager());
return pmLocal.get();
}

public static PersistenceManager getPersistenceManager() {
PersistenceManager pm = pmLocal.get();
if (null == pm) {
throw new IllegalStateException(
"You must call initPersitenceManager 
first.");
} else if (pm.isClosed()) {
throw new IllegalStateException(
"The persistence manager is closed. Was 
close called on it before
you expected.");
}

return pm;
}

private static PersistenceManagerFactory getPersistenceManagerFactory
() {
return pmfInstance;
}
}


RPC Service Implementation Method
///
PMF.initPersistenceManager();
try{

// Call some methods that call this -> PersistenceManager pm =
PMF.getPersistenceManager();

}catch (Exception e) {
// Handle Exception in a graceful way
}finally{
PMF.getPersistenceManager().close();
}

[appengine-java] Using Castor with GAE

[marwen]

Hello,
I'm trying to use Castor in the server side of an appengine
application in order to initialize the datastore with xml-performed
data. I put the xml init file in the war directory and I add castor
jars and its dependencies in the war/lib directory. But I got
something like that :
AccessDeniedException : could not access castor.core.properties in C:
\Program Files\...\jre6\lib

I'm using the Eclipse 3.4 with appengine 1.2.0 plugin
Do I something wrong ? Is castor supported by GAE ? If it doesn't, is
there something to bypass this issue ?

Thanks in advance
Marwen

Re: [appengine-java] AppEngine Blob data type limits

[Don Schwarz]

Datastore Blob fields are limited to approximately 1M each:

http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/Blob.html

If you need to store data larger than 1M, you'll need to use the new
Blobstore API:

http://code.google.com/appengine/docs/java/blobstore/

You then store a BlobKey to a larger block of data in your CacheEntity.

Re: [appengine-java] Wrong calculation of week in App Engine

[Don Schwarz]

I suspect that WEEK_OF_YEAR and YEAR do not generally behave the way you
want.  See this bug for more details:

http://bugs.sun.com/view_bug.do?bug_id=4267450

As for why this works for you locally and not when deployed to App Engine, I
don't have a satisfactory answer.  Have you verified that the timezones are
the same (by adding "zzz" to your format string) ?

Re: [appengine-java] Re: Scope of datastores -- accessible across multiple GAE applications?

[Sandeep Sathaye]

An abstraction layer is required on top of Google Bigtable to achieve this
kind of functionality. We are trying to achieve this through JDBC & SQL
route. Please check out this link (http://www.cloud2db.com).

[appengine-java] AppEngine Blob data type limits

 Does anyone knows why I'm getting the following exception when Blob 
field is used ?

 The documentation doesn't mention any limits for that data type.

long.  It cannot exceed 100 characters.

[appengine-java] Re: Datastore W/O JDO or JPA??

[jd]

Twig http://code.google.com/p/twig-persist/

I think its the only one that doesn't make you deal with Keys
(including JDO) ... correct me if Im wrong here.  You just use normal
object references to other entities and define them as @Parent's
@Child'ren or even @Component's so that its properties are embedded.

[appengine-java] Wrong calculation of week in App Engine

[Raphael André Bauer]

Hi,


I am currently using this code to calculate the week of the year:


===snip
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(millisecs);
DateFormat formatter = new SimpleDateFormat("ww");

String timeStamp =  formatter.format(calendar.getTime());
===snap

Using the timestamp of now (1262000152901L) my local machine tells me:
"200953"  what is correct.

However, if I execute the very same code on the App Engine I get week
"200901" (!) what is strange, because the year is correct, but the
week is not...


Any ideas?

Thanks a lot!



Raphael

[appengine-java] Re: hijacked domain

[Roman]

I just fixed it and my site http://www.dailydev.org is back!

What I did was, that I disabled Web Pages service in Google Apps,
which is already not supported and Google is just trying to get rid of
it migrating existing web pages to Sites. Then I was able to remove
www mapping in Sites without error and also was able to create it once
more. After few minutes it started to work again.

[appengine-java] Re: wrong redirection to google sites

[Roman]

I just fixed it and my site http://www.dailydev.org is back!

What I did was, that I disabled Web Pages service in Google Apps,
which is already not supported and Google is just trying to get rid of
it migrating existing web pages to Sites. Then I was able to remove
www mapping in Sites without error and also was able to create it once
more. After few minutes it started to work again.

br,
Roman

[appengine-java] 1K results query limit removed?

[Stas Chizhov]

Hi,

I'm able to get much more than just 1K entities in one query (I was
observing up to 8K rows).
AFAIK there query result set is supposed to be limited by 1K entities.
So I'm a bit confused - was this limit relaxed recently or am I
getting something wrong?

Thank you,
Stas.
