[appengine-java] How to assing an enitity to two different enitites ?
Hello,
I would like to build an web application where the entity relationship looks
like as follow:
User 1 - * Possibility * - 1 Country
1 - 1 Profile * - 1 Country
*initialization and persistence*
User.getPossibilities().add(Possibility);Possibility.setCountry(Country);
User.setProfile(Profile);Profile.setCountry(Country);
em.persist(User);
*I got this error below*
WARNING: Exception:Detected attempt to establish CPossibility(no-id-yet) as
the
parent of CUser(46)/CProfile(47)/CCountry(48) but the entity identified by
CUser
(46)/CProfile(47)/CCountry(48) is already a child of
CUser(46)/CProfile(47). A
parent cannot be established or changed once an object has been persisted.
Does this concept goes against the GAE datastore hierarchy ?
There are many situation when we have to share the same locations among the
individual object.
What is the real solution on this issue ?
Thanks in advance.
cscsaba
*PS:Implementation of the entities*
... CUser
@Entity
public class CUser {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name=USER_ID)
private Key Id;
private String email;
@OneToMany(cascade = CascadeType.ALL)
private ListCPossibility Possibilities = new
ArrayListCPossibility();
@OneToOne(fetch = FetchType.LAZY,cascade = CascadeType.ALL)
private CProfile Profile;
... CPossibility
@Entity
public class CPossibility {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name=POSSIBILITY_ID)
private Key id;
private String name;
@ManyToOne(fetch = FetchType.LAZY,cascade = CascadeType.ALL)
private CCountry country;
... CProfile
@Entity
public class CProfile {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key id;
private String phone;
@ManyToOne(fetch = FetchType.LAZY,cascade = CascadeType.ALL)
private CCountry country;
... CCountry
@Entity
public class CCountry {

[appengine-java] Re: Sending mail in transaction
The request headers will not help.
You'll run into problems whenever you are doing an api call that
return with an unknown state and the method you are calling is not
idempotent (like sending mail, creating a contact etc.)
So in case of email you can add your app as bcc and use a mail-in
handler to check whether the mail has been sent successfully or not.
This is an ugly workaround but there is nothing else that comes to my
mind.

Maybe if you combine this with specific catch blocks for mail exceptions?

Pieter,

problem is that task has to be idempotent to achiev desired behaviour,
a queue task can be executed for example twice, since those are
specifications
and this would result in sending mail twice,
a naive aproach would be to update some db lock to prevent sending
mail more than 1 time,
but it is not easy, this is much more complicated,
in other words operation is either atomic or it isnt, and without very
precise mechanism you
cannot prove that task will be runned only one.
My own tests proved that due to email quota being reached (task fail
and has be resheduled) some of the mails
has been send twice.
If Mail API would allowed to send mail only in case of some db
transaction success it would be very easy to garant
that mail will be send exactly 1 time. (although if it fails for some
other reasons like recipient not found or so thats whole another
story :)
Basically this can be solved by
1) adding new API for sending mail (dont know if it so easy or whole
problem isnt much much bigger than i think - distributed
transactions ?)
2) implementing locking mechanism

Create a task for sending e-mail instead of calling the mailservice

use this in your task (a task can be part of a transaction)

and all exceptions will be catched. I think a task will be re-executed
only
if it fails (throws an exception).

4) bind sending mail with current transaction (similar to

5) db transaction.commit()

[appengine-java] How long is my application state hold on the app engine?
hello everyone, i want to collect some performance figures of my app on the server side. but i do not want to persist them in the database, i only want to collect them by changing the state of some class (i.e. changing class members like number of requests, number of method calls, etc). i want to read these values on the client side and display them in an administration panel (or a profiler-like ui). but currently i think the application state is at least lost after each new deployment. is this the only time the state is resetted? does a jvm holding my application state run all the time between each deployment? i have the same question regarding static members. i use singletons or static variables on server side to make sure they are constructed only once whenever their construction is expensive. so i want to make sure that the jvm holding the instances is running for a very long time to avoid reconstruction of them. however, it feels like the jvm is restarted relatively often (due to very low load on my app maybe) and thus the singletons are recreated during the jvm startup. kind regards, ingo -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Sending mail in transaction
I was thinking about storing some unique string which is derived from
email content and recipient (i have some unique stuff sending in each
mail)
and store in memcache/db, I know its not bullet proof but at least in
case
some possible 2x sending mail would be filtered.
Concept :
Check flag if set we know we did send
Send mail, if successful, set some flag in memcache/db
I am aware ITS NOT BULLET PROOF, but maybe can filter some cases, when
same task
is triggered after that interval neccessary to change/store flag.
What you think ?

So, if you are directly accessing the stream, it is still in memory
and not stored anywhere. I think you should try logging the stream you
receive. I think it is hitting a null ptr exception for some reason.
did you use printstacktrace in your catch block?

Hi, Did you install Eclipse as root? Did you perform the upgrade as non-root? There is an issue in Eclipse with installing it as root, and then updating plugins as non-root.

Re: [appengine-java] Re: How to upload primary key as an id instead of name
You can do this now using the RemoteDatastore Java utility
http://code.google.com/p/remote-datastore/
For example, this code runs on your desktop and creates a single
entity in your live datastore:
// divert datastore operations to live application
RemoteDatastore.install();
RemoteDatastore.divert(http://myVersion.latest.myApp.appspot.com/remote-datastore
, myApp, myVersion);
// create an entity with a numeric key
Key key = KeyFactory.createKey(MyKindName, 35);
Entity entity1 = new Entity(key);
entity1.setProperty(property1, hello);
// put entity to the remote datastore
DatastoreService service =
DatastoreServiceFactory.getDatastoreService();
datastore.put(entity1);
This also works for bulk puts

Hi guys
I came across plovr today, which has made my life a lot easier, so I
wanted to share.
It is wrapper for the Closure JavaScript compiler that will compile on
the fly and serve the compiled JavaScript from it's own server. This
makes it really easy to develop an application locally with AppEngine,
without having to server all the individual closure dependencies.
Once you've set it up with a simple JSON config file, you simply
insert a single script tag hitting this location:
http://localhost:9810/compile?id={projecthttp://localhost:9810/compile?id=%7Bprojectid
here}
When you change the JavaScript files, all of the source files will be
automatically recompiled.
Here's the getting started guide:

I would use the key's id and not the full key which contains too much private information. Also, at a minimum, convert the id to base64 url friendly.

[google-appengine] How do i reload my app(google wave robot) in app engine
i have deploy a wave robot on to app engine. it works as expected, i then make some change to the code, deploy it on the same app engine version the change i made was not in effect. according to https://groups.google.com/group/google-appengine-java/browse_thread/thread/60ea6c16f1f0dab9/d1792c101518ed0f?lnk=gstq=restart#d1792c101518ed0f i can restart it by disable it in the admin page and then re-enable it but that does not work (it still use the old codes) i also tried disable it w/o re-enabling back. the robot still work without error and using the old code. i hear some ppl mention about development mode tab, but i cant seem to find it in eclipse. i dunt think it will work for wave robot since i cant run the robot locally. i have post a similar question on wave api group. this is really a letdown for me who is starting to learn about wave robot and app engine. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Opening a JSP editor results in eclipse not responding
Hi, I have run into some problems with eclipse and hope that someone here can help me. I created a GAE project and wanted to experiment with some basic JSP stuff. I run into the known problem that I have to install a JDK. After doing so, problems got worse. When I now try to create or edit a JSP page, eclipse freezes. I've tried the 64bit version of Helios in combination with Java 6 Update 21 (64bit), as well as the 32bits version of Helios in combination with the 32bit version of the JDK (after uninstalling the 64bit versions), both on the same 64bit Windows 7 computer.

[google-appengine] Loading Seed Data for Unit Testing
Hi,
We are using JPA for our Dao's to interact with the datastore. I was
wondering is there is a way to load seed data for unit testing. I can
insert the entities using JPA in the setup() method here
private final LocalServiceTestHelper helper = new
LocalServiceTestHelper(new LocalDatastoreServiceTestConfig());
@Before
public void setUp() {
helper.setUp();
}
but I was wondering if the LocalServiceTestHelper / anyother has a
convenience method for loading the seed data from an XML file. The
data would be present like this
?xml version='1.0' encoding='UTF-8'?

Re: [google-appengine] users.get_current_user() returning None for https requests
It's not clear from your message if you login again before accessing your https URLs or if you just change the protocol part of the URL from http to https (i.e. adding a s) or do you login again before hitting your URL using https? The cookie you'll receive for http isn't valid for your https URLs, so you need to login again.

[google-appengine] Re: ~200 ms or 200 ms lags
Thanks for Your answer! Aral Balkan's example is very old and I'm aware of that. You suprised me by the technological jump of pyAMF, but unfortunately upgrading it has no effect in my case (probably because I don't send/get a lot of data, so pyAMF can't show off it's serialization/deserialization skills. OLD: http://0.latest.lagstest.appspot.com/gra NEW: http://1.latest.lagstest.appspot.com/gra Probably 50 ms offline lag is a fault of flash. But still, without these 50 ms lag server will have 150 ms, while it pings with 50. Maybe there's some multi wrong techniques stacked one on eachother. I will never know that until I see some better lag tester, that accomplishes ~50 ms (well, any under 150 ms will be nice) online lag. So I repeat my questions and add more of them: 1. Does anyone have similar GAE lag tester? I don't care about technology, I care if it shows different pings. 2. Ad 7: does anyone know if there's something more in Aral Balkan's example that's ancient and wrong nowadays? 3. Does the God exist? 4. Is there any flash group I could ask it as well? (I'm kinda not a group discussant type and I'm not oriented...) Thanks for Your try, Nick! And I'm looking forward to next hints!

Check out Brett Slatkin's IO talk: http://code.google.com/events/io/2010/sessions/high-throughput-data-pipelines-appengine.html And the 'mapper' implementation: http://code.google.com/p/appengine-mapreduce/ Robert On Mon, Jul 12, 2010 at 8:13 PM, Phil McDonnell phil.a.mcdonn...@gmail.com wrote: I see how this is possible, but it feels very clunky.

Should I be using some sort of mapreduce? If I should use some sort of mapreduce framework, how does that integrate with GAE? My user base right now is small, but I intend to scale this.

[google-appengine] Re: Opening a JSP editor results in eclipse not responding
As a troubleshooting step I would suggest creating a java project that is not a GAE project, and verifying that it works and you can edit JSPs. Alternatively you can uncheck in your existing project properties the checkboxes Use Google App Engine and This project has a war directory in the Google settings. If it is a general Eclipse problem (not related to GAE), then other java forums will be more helpful. Also try a bare bones simple hello world size JSP. The JSP editors in eclipse are slow and tend to break once in a while on big JSP files. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: HTTPS on my own domain
Thanks. Do people have an estimate of the increased cost of using HTTPS over HTTP (due to more CPU cycles)? On Jul 2, 11:28 am, J j.si...@earlystageit.com wrote: We don't use any cookies until the user logs in and once they log in, we stay on https for all traffic. Hopefully we don't run into performance problems. While we consider the http channel and the https channel to be completely separate, the common elements are the App Engine (and the browser). We'd probably do the sharing in the application code on App Engine if we get backed into a corner for performance reasons. Perhaps someone else on this list has a suggestion? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: datastore keys security question
I use entity keys as parameters for some things. If allowing someone to know the app-id of your app is a security risk you may need to evaluate your security; besides if you want to use SSL the app-id is public knowledge anyway. (Sometimes) I also use the key when I want to allow multiple an entity that may be of different kinds to be requested. The handler can decode the key and validate that it is an acceptable kind very easily. Besides, someone knowing the kind is names 'Issue' should also not pose a major threat, the user facing form is probably already titled 'Issue:' :) The documentation explains how to get a key's id or name on the Key class page: http://code.google.com/appengine/docs/python/datastore/keyclass.html You can read about how to get an entity's key here: http://code.google.com/appengine/docs/python/datastore/modelclass.html Deciding who is allowed to do an action depends on the structure of your application. For some of my apps on the user who created an entity can edit/delete it. So my test is simple, load the entity and compare the 'user' field to the current user. If they differ then I raise an exception and return.

You simply asked for db.Key(mykey)? Is it possible to get other informations for this entity, from another app-id ? Jeff, I can't find the key's id using datastore view or in documentation. The idea is to have 4 commands /add/application, edit, remove and view. the 'view' command will be used to display content to my visitors (unauthenticated). add/edit/remove will verify if that key belongs to that user How you guys do something like that ?

Re: [google-appengine] how to get the id of key of SelfReferenceProperty
SelfReferenceProperty should just return a db.Key. So assuming the property is set, normal Key methods should work. I have two suggestions: 1) Unless you are intending to dereference (ie perform another db.get()) those entities, use the get_value_for_datastore method. http://code.google.com/appengine/docs/python/datastore/propertyclass.html#Property_get_value_for_datastore And, 2) Avoid using Parent as a property name, parent is reserved. That is just asking for bugs caused due to a easy to make typo. http://code.google.com/appengine/docs/python/datastore/modelclass.html#Disallowed_Property_Names Robert On Jul 13, 2010, at 12:14, saintthor saintt...@gmail.com wrote: class x( db.Model ): yy = db.ReferenceProperty( y ) Parent = db.SelfReferenceProperty() use yy.key().id() is ok, but Parent.key().id() is invalid. tell me SelfReferenceProperty have no attribute Key. how to get the key id then? -- You received this message because you are subscribed to the Google Groups Google App Engine group.
