[appengine-java] Re: Objectify: IllegalAccessError

[GeneralSlaine]

Jeff,
I'm using 1.3.8 I think reading from this Jar file: appengine-api-1.0-
sdk-1.3.8.jar.
However, this version dates from october 2010, not that old!
So I have to upgrade?

Re: [appengine-java] Objectify: IllegalAccessError

[Felipe Teixeira]

Hi, Brother,

Your solution ;

Objectify ofy = ObjectifyService.begin();
 ObjectifyService.register(AutorizacaoDAO.class);
com.googlecode.objectify.Query q =
ofy.query(AutorizacaoDAO.class).filter("email",
email).filter("senhaautorizada", senha);

[appengine-java] A couple of datastore questions!

[Muhammad Ijaz Khan]

Hi,
I am building an application and have used JDO for datastore for
implementing use cases. Now when I am implementing the backend machine which
is a bit complex in relationships among objects then I am facing hard times
with JDO (May be due to lack of my knowledge). I have following questions to
ask,

1. Can I use reference of objects in more than one classes? For example,
Class A is persistent and being used as foreign key in Class B and Class C.
Do I need to create unowned relationships through Key or can I use some
annotation (or something) to mark a field of type A as foreign key? When I
make a field of type A in class B, and assign an object of class A to it, it
is stored as new object as child of B :s

2. Can I use objectify for this use case only (mixing with jdo) and will it
simplify stuff or not, any experience comment?

Thanks in advance.

regards
Ijaz

Re: [appengine-java] A couple of datastore questions!

[Luca Matteis]

Owned relationships are a bit weird in my opinion. I was having your
same issue. I had a `MyImage` class that was defined inside two
different classes. This didn't work... I didn't quite understand why
and so to avoid all weirdness I decided that for more complex
relationship cases I would always use unowned relationships (defining
the Key of the reference object instead of the object itself).

So I only use owned relationships when the child object can only exist
under 1 (and only 1) parent.

Hope this helped... it's only what I experienced... I'm not a JDO expert.

Re: [appengine-java] A couple of datastore questions!

[Muhammad Ijaz Khan]

This is exactly what I am doing for now but was wondering if there is a
better way and better way of loading the actual object from key. Thanks for
your comment as it reduced my loneliness :)

Re: [appengine-java] Re: GAE Teams Content-Transfer-Encoding: base64 data uploads don't work.

[Ikai Lan (Google)]

Could just be blobstore weirdness. I don't have a chance to get to this
soon, but can you file an issue in the issues tracker? We'll categorize it
and check it out during our next scrub.

It could be operator error, but if that were the case it would mean 1. our
SDK needs to be updated to reflect behavior in production 2. We need to
update the docs.

[appengine-java] NoSuchMethodError totalMemory()

[emurmur]

My app started throwing exceptions right after the latest maintenance; 
 apparently Runtime.getRuntime().totalMemory() is now actually removed from 
the server runtime?  Couldn't you just return zero?

java.lang.NoSuchMethodError: 
com.google.apphosting.runtime.security.shared.intercept.java.lang.Runtime_.totalMemory(Ljava/lang/Runtime;)J
at 
com.conceptualcalculations.util.MemoryUtils.formatMemoryLog(MemoryUtils.java:23)

[appengine-java] Index Names now throwing an error

[Matt Farnell]

Hi there,

I have an app in production which has been working for over a year with an
index defined like so

   






I went to make a modification to another unrelated part of the app and tried
to deploy it however it now throws the following error.

   Unable to update app: Error posting to URL: xxx

400 Bad Request

Error when parsing index.yaml:

Unable to assign value '201012' to attribute 'name':

Value 201012 for name is not of the expected type str



So existing index names that did work are now preventing app deploys??

[appengine-java] Re: NoSuchMethodError totalMemory()

[Didier Durand]

Hi,

An answer from google is needed as Runtime still is in the whitelist:
http://code.google.com/appengine/docs/java/jrewhitelist.html

So, it should provide all the methods of the regular jre class.

regards

didier

[appengine-java] Re: GAE Teams Content-Transfer-Encoding: base64 data uploads don't work.

[Brandon Donnelson]

I thought I'd try maximum encoded line length and put a CR/LF at the end of 
each line of base64, so far no luck on GAE side. 

I'm changing directions for now, I'm going send my base64 images from canvas 
through RPC in chunks, and decode and write to blob on the server side. This 
will allow me track the upload and retransmit sections on failure.

Hi Rambo,

Have you installed  google plugin for eclipse?
If it is installed, you can upload your application from eclipse.
