[appengine-java] Re: how to persist a list of bytearray?

[Khanh Dao Minh]

Dear Tao,

As I understand, you should not use byte[] in GAE store. GAE only support 
some core value type here: 
http://code.google.com/appengine/docs/java/datastore/entities.html#Properties_and_Value_Types

So I think you may change to ShortBlob:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/ShortBlob.html

Here I go:

private List attachments = new ArrayList();
ShortBlob foo = new ShortBlob(new byte[]...);
attachments.add(foo);

Hope this help.
KhanhDM.

[appengine-java] Re: jetty java.lang.IllegalStateException: STREAM

[Ian Marshall]

Hello Mark,

I get this sometimes too on the GAE/J developmenr web server after the
next web page has been served. I do not find this exception to be
reliably reproducible: sometimes it happens, usually is doesn't.

I am running GAE/J 1.4.2 with the JDK 1.6.0_24 for Microsoft Windows
XP.

An example of my errors are:

  org.apache.wicket.WicketRuntimeException: Unable to write the
response
at org.apache.wicket.Response.handleException(Response.java:286)
at org.apache.wicket.Response.write(Response.java:310)
...
  Caused by: java.io.IOException: Closed

at org.apache.wicket.util.io.Streams.copy(Streams.java:126)

... 32 more

This is followed immediately by what you get:

  java.lang.IllegalStateException: STREAM
at org.mortbay.jetty.Response.getWriter(Response.java:616)

[appengine-java] Design choices.

[sledorze]

Hi!

I am currently building an app that will be sell as a customized
service to few but big (in traffic) clients via some integrators.

This app is a backend for a model on which you can put cothes and
create outfits in the browser.
The stereotypical final client is an e-commerce selling company and
the integration is done in its web site and IPad, IPhone, etc..

Having several clients, I was wondering if I am allowed to make
several apps.
These are the reasons why:
- Each client integration requiers specific code and/or datastore
modifications and to host possibly specific datas.
- Each app can behave differently, has different load and I need to
track that down for evaluation of the costs.

However; I've read that Google prevents doing one App diguised into
several App.
I really don't know if my use case apply.

Today, I've start to build everything as a single app but I am not
very confortable as I could have a lot of struggle on the whole
service due to the number of maintenance scenario and the explosion of
schema models and View / Controllers for each client in the same App
(even if there's no schema in the datastore, I must have one in my
mind).
But one have to realize that the first versions will be identical.

I would need an answer, and would like to have it for granted if my
use case applies or not to the formentionned restriction.
What's your advice?
Whould should I contact?

Thanks for your answers,
Stephane

Hi Stephane,

You can manage multitenancy using Namespaces:
http://code.google.com/appengine/docs/java/multitenancy/multitenancy.html

With each client (tenant), you can have difference setting in their 
namespace, then apply difference business logic within a single application.

KhanhDM.

[appengine-java] Re: Design choices.

[sledorze]

Very interesting indeed!
Got to test that.
I am wondering if this this feature makes all datas part of an group
or not in the datastore? (i.e. implemented using parent keys)
I am asking this in order to know if there some possible performance
loss (like write contention) that could arise from using it.
Thanks!

I think there is no problems with performance, but security vulnerabilities

Just give it a try :)

If you are seeing this problem:
http://permalink.gmane.org/gmane.comp.systems.google-appengine.jre/18014

This is fixed in "1.4.2 - 2011-02-16", look closely at the Location of
the App Engine SDK under Preferences -> Google -> App Engine and make
sure you don't have v201102111811.

[Didier Durand]

Hi,

namespaces are not related to entity groups: entity group is a notion
to group entities for transactional purposes. The aim is to limit a
transaction to update of objects in a single group (i.e on the same
server) to get a higher reliability and good scalability.

The namespace is a just a "prefix" on your data to separate it
virtually per namespace: it has nothing to do with entity groups. Of
course, you can't define entity groups across namespaces as data in
one namespace doesn't know of data in another.

regards

didier

[appengine-java] Datastore not responding intermittently

[emurmur]

We are testing a update to our app on a couple of qa instances 
(applications, not just JVMs) of AppEngine.  Both are getting 
DeadlineExceededException pretty often.  However, we have only a single user 
hitting the database and it has little data in it - basically, there is no 
contention for the database, but sometimes it simply does not respond. 
 Below is an example log.  You can see that we use JDO to emit a query for a 
single entity.  However, the datastore never responds.  We have the same 
exact code running on two different AppEngine applications.  One of them has 
instant-on enabled (so it has 3 instances running all the time) and the 
other does not (so it needs to spin up an instance relatively regularly). 
 We are using JDO and Restlet, but not Spring or Grooving or other packages 
that take a very long time to initialize (initializing a new instance takes 
our app about 7 seconds).  The very similar code on our live application 
seems to be fine - we are not seeing the same thing.  This makes me worry 
about deploying to live.  Is anyone else seeing this kind of behavior with 
the datastore?

Hi,

Did you add the .jars specific to the local dev server in the
classpath of your IDE ?

regards

If by "jars specific to the local dev server" you mean 

   - appengine-local-runtime.jar
   - appengine-api-stubs.jar

Yes... I just barely figured out that these were needed (after much 
frustration and running across a post from two years ago that mentioned 
these jars).   That was all I needed!   Thanks for replying all the same!

P.S.  If anyone who manages the docs is watching... Would REALLY have 
appreciated some mention of that on the Local Unit 
Testingpage
 in the documentation.   Perhaps it went without saying for some but not 
for me.

P.S.  I'm an idiot and did not read the Local Unit 
Testing 
page 
in the documentation carefully enough;  I missed this:
However, if your tests or code under test have these dependencies you'll 
need a few more JARs on your testing classpath:
${SDK_ROOT}/lib/impl/appengine-api.jar, 
${SDK_ROOT}/lib/impl/appengine-api-labs.jar, and 
${SDK_ROOT}/lib/impl/appengine-api-stubs.jar. These JARs make the runtime 
APIs and the local implementations of those APIs available to your tests.

[James Andersen]

Just for my own edification...  I was comparing the build path of my test 
project to my GAE project while trying to solve this... I didn't find these 
jars in either one.When I launch my GAE project locally is "works" of 
course...I'm using eclipse, does the "Google Web Application" launch 
configuration handle loading these jars for me before my project is actually 
loaded?   

Sorry still getting used to GAE and have been in the .NET world for several 
years now...
