[appengine-java] Re: Changing the Parent of a child entity
As of now I would confirm that, and of course I didn't mean new
school in any sense dogmatic, it's just different ways of doing
things on different platforms. I'm even going more and more towards
NOT having relationship fields on GAE at all, even unowned in the JDO
sense. Means not even storing keys in a field/array of the parent.
We'd rather have a field like this on the child:
@Persistent
@Extension(vendorName=datanucleus, key=gae.parent-pk,
value=true)
private String parentKey;
Set its parentKey explicitly and look up all children with a key query
as described above. This gets rid of referential integrity hassle
because you don't have to make sure the key is ALSO stored in the
parents list of child keys... you just always get the actual list of
keys and can be sure you've got all of them.
There is more issues with JDO coming ing when removing children from
lists of child objects in detached state you might want to be aware of
(e.g. check out the test project here:
http://code.google.com/p/datanucleus-appengine/issues/detail?id=218 ).
Best,
Fred

I guess that makes sense and your example is dot on. I was wondering
are there real life applications on GAE where people are using JDO/JPA
relationships. The more the problems that I face with relationships
and the more I read about it, it seems that unowned is the way to go.

There are many Use Cases where it makes sense to keep relationships or
you at least want to leverage the power of entity groups even with
JDO. The school-of-thought is a bit different than in other
environments though. While JDO parent to child access is comfortable
it makes not the best use of GAE's massive scalability and performance
advantages. One example:
Say you have a user and all his comments are children in his entity
group. Now in an old school way you would check how many there are is
user.getComments().size() ... well that works but would have to load
the entire array from the store. The new school way of doing this
would be running a query filtered on keys that is an order of
magnitude
faster:http://code.google.com/intl/de-DE/appengine/docs/java/datastore/queri...
You can always retrieve the parent object (user) because its key is
encoded in any of the child keys.
There are many more examples where you have to think different, but in
general: It makes sense to have entity groups where they persist in
reality: users - comments, users - addresses, bank accounts -
transactions, and so forth...
Hope this helps,
Fred

Hi Fred,
Thanks for your response. This is what I suspected too that the entity
groups might not be able to change. This actually brings me to the
conclusion that we might not want to keep any owned entities at all.
We are in the process of converting a legacy application to GAE and in
the process we have been breaking out relationships due to multiple
problems. I would write about all the problems that we faced and the
workarounds and link it here.
This relationship was probably one of the last bastions that we had
remaining. With what you mentioned this might have to be broken too
since a user can move around departments as a valid business case.
So let me ask the community this question, does anyone see the benefit
of maintaining relations at all? using JPA/JDO. From the complex
queries that a normal web app would have you would fall into
situations where you would need to use more and more of unowned
relationships. Is that true? or am I missing something.

You have to use unowned relationships and not place the department and

See:http://code.google.com/intl/de-DE/appengine/docs/java/datastore/relat...
use for UserDepartment:
private SetKey users = new HashSetKey();
and for User:
private Key userDepartmentKey;
Entity groups cannot be changed once being established.
If you want the relationships like you have them, you would have to
change the Key of the User object (it's identity) to place it in the
entity group of another department, since the department's (parent)
key is part of the user key like in a path.

[appengine-java] appcfg bulkuploading Listkey values from csv
Hi, i'm trying to upload to my app an entity with a field which is a
list of keys. How can i do it?
I tryed to separate it with comas and wrap it with double quotes,
like:
key,extensions,name,number
1,34,56,John Doe,699
And the config.yml:
kind: Zone
connector: csv
connector_options:
property_map:
- property: __key__
external_name: key
export_transform:
transform.none_if_empty(transform.key_id_or_name_as_string)
- property: extensions
external_name: extensions
import_transform:
transform.none_if_empty(transform.create_foreign_key('Extension'))
export_transform: transform.key_id_or_name_as_string
...
But it's interpreted like a single Key and not a list of Keys.
Anybody knows?

If you use this: http://code.google.com/p/remote-datastore/ you can
upload Entities in a main(String[]) using the simple low-level API.
If your data is in CSV format you'll need to parse the file lines to
create your Entities.

Re: [appengine-java] Google Web Application problem in Eclipse Helios
Are you trying to create a new application? You can do that with the plugin under File-New-Web Application Project, which will let you choose whether or not you want to use GWT or GAE or both. (That is what the link you posted is talking about). You can use JSP on GAE (as described in the AppEngine docs herehttp://code.google.com/appengine/docs/java/gettingstarted/usingjsps.html). The easiest way to get there (get the setup, paths, etc. correct) would probably be to create a new Web Application Project (File-New-Web Application Project), uncheck Use Google Web Toolkit and check Use Google App Engine. Then follow the example in the AppEngine docs. If you use GWT, the starter web application (create new Web Application as above, but check Use Google Web Toolkit) will have an example of a servlet GWT style, using GWT RPChttp://code.google.com/webtoolkit/doc/1.6/DevGuideServerCommunication.html. This will work on AppEngine. GWT can also be used with other servlets though. kathrin On Mon, Aug 2, 2010 at 5:40 PM, asfh hd.a...@gmail.com wrote: Hi, I just installed Eclipse Helios, followed by the Google plugin for eclipse with the both the GWT SDK and the GAE SDK, The installation completed successfully (I Event performed it twice), When I want to create a new Servlet (or any other JSP class such as Filter), the Create Servlet Dialog project field does not show any Google\Web Application project, but only Dynamic Web Projects, How can I fix this??

Re: [appengine-java] Google Web Application problem in Eclipse Helios
Are you trying to create a new application? You can do that with the plugin under File-New-Web Application Project, which will let you choose whether or not you want to use GWT or GAE or both. (That is what the link you posted is talking about). The specific issue raised by the original poster (I had it too) was that once you define a Google Web Application Project, it creates one servlet for you, but gives you no way to create additional servlets using the File ... New ... menu options. You can create a new class and make it into a servlet, or copy an existing servlet, but then you lose the web.xml autoconfiguration that you get when you generally create servlets in Eclipse.

[google-appengine] Re: Previously attached subdomain still bound to the deleted appengine application
I think i didn't delete the app and subdomain association before disabling/deleting the application. Is there a way it could be cleared up now that the application is already deleted? anyone from Google Apps or Appengine team?

To delete your app, you first disable it, which stops all serving requests but leaves your data and state alone. Once your app is disabled, you can leave it that way, or you can delete it. While your app is disabled, you can still use the Administration Console to manage it.

[google-appengine] Asynchronous URLfetch Google Analytics. What happens when I don't call get_result()
Hi! I'm using Google Analytics for Mobile Browsers wherein I connect with Google Analytics servers via my appengine app to track users. For performance reasons, I'm thinking of using asynchronous URLfetch to call the google analytics tracking url near the middle of my request handler code. Well, I'm not really interested in the result of that urlfetch, so I'm not interested in calling get_result(). So I don't want my app to wait for the result, and just increase the time for the user to wait. I just want it successfully called. The documentation for Asynchronous URLfetch (http://code.google.com/ appengine/docs/python/urlfetch/asynchronousrequests.html) states If the app request timer expires while the app is waiting, the call is canceled. What does it mean by the call is canceled? My current request handler usually returns within 40-70ms (without the urlfetch), and I'd like to keep it that way. I haven't tested this in production. Will this be an OK practice? Thanks! -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Asynchronous URLfetch Google Analytics. What happens when I don't call get_result()
If you just want to call an url and you don't need the result, you can perform the url fetch in a task and just add that task to a queue from your request handler.

[google-appengine] google app question for a chat bot
Hi,
I have some confusions with Google App which I hope by getting some comments
from you regarding to the question I put here, will be eliminated.
I used a tutorial from:
http://gaejexperiments.wordpress.com/2009/09/25/gaej-xmpp-and-rolling-your-own-agent/
and built a simple echo-chat-bot as explained there, and deployed to my
Google App account. Then I tested it with my Google Talk, and it worked as
expected.
Next, I used another tutorial code to connect to Google Talk first just to
be sure I learned to connect to:
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
public class ChangeStatusMsg {
public void changeStatus() throws XMPPException {
ConnectionConfiguration connConfig = new ConnectionConfiguration(
talk.google.com, 5222, gmail.com);
XMPPConnection connection = new XMPPConnection(connConfig);
connection.connect();
if(connection.isConnected())
{
System.out.println(Connected!);
System.out.println(connection ID: +
connection.getConnectionID());
}
else
System.out.println(NOT Conected!);
}
public static void main(String[] args) throws XMPPException {
ChangeStatusMsg changeStatusMsg = new ChangeStatusMsg();
changeStatusMsg.changeStatus();
}
}
This code also worked. I got Connected!, and a connection ID:
B8E524DA1A107B2E.
Next I change the connection data with my echo-chat-bot to test the
connection with the bot:
ConnectionConfiguration connConfig = new ConnectionConfiguration(
apps.google.com, 5222, mybot); //suppose my bot is installed on:
mybot.appspot.com
This fails :-(
What is the right way to express the connection, if this is possible at all
please?

[google-appengine] my first xmpp chat client problem
Hi,
to build and test the tutorial of this book:
http://eclipserpc.org
I built a simple echo-chat-bot on my Google App account, to connect to
it from the chat client tutorial of the book. My bot is now working by
echoing whatever written to, from my GoogleTalk:
coolestzab...@appspot.com.
I fail with connecting the chat client of the tutorial to it. I think
my problem is that I don't know how express the connection in program.
Bellow I provide the problem in detail, and there all the tutorial
code I used both for the server bot and the client (from the book).
Please give some ideas to help to solve the issue (connection time
out).
The tutorial main class:
public class Application implements IApplication, MessageListener {
public Object start(IApplicationContext context) throws Exception {
XMPPConnection con = new XMPPConnection(eclipsercp.org);
try {
con.connect();
con.login(reader, secret,
Long.toString(System.currentTimeMillis()));
Chat chat =
con.getChatManager().createChat(el...@eclipsercp.org, this);
chat.sendMessage(Hi There!);
Thread.sleep(5000);
} catch (XMPPException e) {
e.printStackTrace();
} finally {
con.disconnect();
}
return IApplication.EXIT_OK;
}
//...
Please tell me, if the right way is to change eclipsercp.org there
for talk.google.com and the el...@eclipsercp.org with
coolestzab...@appspot.com? if so
points:
1. I built the Google App using the Eclipse plugin of GApp and
deployed successfully, so my internet connection and Eclipse setup is
correct.
2. My Google Talk connects to the bot, so connecting is also possible
without problem.
3. I have no login/password authentication on the bot, but the
tutorial has, well I suppose I can leave them as-is, as chat-bot just
ignore them.

[google-appengine] Handling federated login failure
Hi, I use federated login for one of my app and tested it with several OpenID providers and relaying parties. In some occasions it did not work and the browser simply receives a 204 response code which leaves the browser on the same page with no further indication of failure. Same thing when entering an invalid OpenID url. How should I do to provide my visitors with some indication of failure?

Re: [google-appengine] Re: Prerelease SDK 1.3.6 is out!
Just a heads up that get_url_base is now get_serving_url() (Python) and getServingUrl() (Java). This is a feature that allows you to generate a URL for images stored in the blobstore so you shouldn't have to write your own handlers for the blob data.

[google-appengine] Re: Asynchronous URLfetch Google Analytics. What happens when I don't call get_result()
Thanks for the reply. That's a good solution to return a response ASAP. But, I'm guessing that adding the urlfetch to a task would consume extra CPU ms time. I want a solution that returns the response ASAP and, at the same time, consumes the least CPU resources. I'm assuming that the docs mean that making an asynchronous urlfetch and not calling get_result() when the app handler returns, results in the call being cancelled. What does cancel mean? Does it mean that it will never reach the analytics service? Thanks! -- You received this message because you are subscribed to the Google Groups Google App Engine group.
