[appengine-java] Adding or deleting a property of an entity...
How can I add or delete a property in a given entity. Let say i have this employee class with properties -Name -Address and i have uploaded it in google app engine and pushed data. Then after some time, i want to add a field like below -Name -Address -ContactNo 1. Should i just add a definition in the class employee and just update it in google app engine? 2. What will the previous data look like and how can I add contactNo to the previous data? 3. What if I want to remove the Address property, should i just remove the address declaration and methods in the employee class? Also what will happen in my data up in GAE? -mar_novice --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: geocoding for IP addresses
One possibility might be to use the downloadable Maxmind database, upload it to GAE datastore and use that to convert the IP-address to a city. Then use some other service to get the latitude/longitude for the city. http://developer.yahoo.com/maps/rest/V1/geocode.html http://code.google.com/apis/maps/documentation/services.html br, Juha On Aug 19, 1:57 am, Toby tobias.ro...@sunnymail.mobi wrote: Hello, I am looking for a way to get the latitude/longitude for the IP address of the user. So far I was using maxmindhttp://www.maxmind.com/app/lookup_city but I can not make it work. It depends on java.net stuff that does not exist in GAE and a 30MB file database. I imagine that maybe google offers a similar REST service or something. I looked around but I can not find anything useful with Java on GAE. Can someone help me?

[appengine-java] HardDeadlineExceededError when try to persist object
Hi , I have 2000 records of an entity in my datastore. I want to make a change in a particular field of the entity for all records. When I try to persist the updated records, it gives HardDeadlineExceededError after updating near about 400 records and it takes more than 30 seconds. Is there any workaround so that the persisting process will remain continue even after 30 seconds? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] JPA Question - Accsing Child object of a detached Parent in JSF
I observed a strange situation using JPA in case of detached object.
If I want to use the Tenant (see bellow) object in JSF page accept the
tenantId field all fields are NULL. But before the return statement if
I access any of the member variable of Tenant Object it works file. I
tried with FetchType.Eager, but no luck.
Is it a known feature or BUG?
This is my entity class a Tenant has one or more user.
@Entity
public class Tenant{
@OneToMany(mappedBy=tenant, cascade=CascadeType.ALL)
CollectionUser hmsUserList = new ArrayListUser();
.
}
@Entity
public class User{
@ManyToOne
@JoinColumn(name=tenant_id)
private Tenant tenant;
}
My function returns the Tenant Object as;
public Tenant myFunction(){
User user = em.find(User.class, ID);
//if add the bellow line it works
// user.getTenant().getName();
return user.getTenant();
}

[appengine-java] GAE- Horizontal scroll bar in logs dashboard..
I don't know where to post this so i just do it here, May I just suggest to add a horizontal scroll bar when looking into the logs.. when the url or link accessed is too long, like for example there are query strings, I can't see the whole query string ang also the cpu_ms, request latency etc. what I do is to highlight all the text (the text that is not displayed on the screen will also be selected), copy and paste it in a text editor. But sometimes it is irritating to do this repeatedly. Well, this is only a suggestion and a simple feature... but if is supported, it would be a great help in monitoring logs.. -mar_novice --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] How are people persisting data for a user?
From the docs it sounds like the User object is based on the email for the user. This seems really bad if you want to persist data for the current user since one day they can change their email address and then you are screwed. I see the user_id() function for python and the fact that this doesn't exist for java seems like a huge mistake. Are people just using User to persist anyway or is there another way around this?

[google-appengine] Re: Apache Jackrabbit on GAE
Hi, We investigated a little bit the very same question, in order to port Liferay (which uses Jackrabbit) under GAE. And instead of migrating all sql/hibernate stuff to JDO, it appears incredibly easier to continue to use jdbc, but to use it with something compliant with GAE. Once said that, there is several options, but the one we selected as the most interesting is jiql driver (www.jiql.org) for Google big tables. We done some promising prototype with that, I invite you to have a look to this project. If you find some good generic solution for file storage (some generic class overriding to reuse any existing stuff), we are more than interested ;-) Best regards, Francois On Aug 18, 12:45 pm, Ben Francis b...@tola.me.uk wrote: Has anyone managed to get Apache Jackrabbit running on GAE? I've seen a few postshttp://www.mail-archive.com/us...@jackrabbit.apache.org/msg11054.htmlon the Jackrabbit mailing list about this and the main problems seem to be: 1. Getting the repository to run on JDO 2. Storing the search index (which uses Lucene by default) 3. Need for threading support Although I wouldn't personally know where to start, getting the repository to run on JDO doesn't seem infeasible. Storing a search index may be possible, Compass supports JDO and the Jackrabbit search engine is supposed to be pluggable. The need for threading support seems more fundamental to me, I'm not sure if there's any solution there. Apart from the yet-to-be-released XMPP, incoming mail and mass storage APIs - not being able to run a JCR implementation is the current biggest barrier for us to use GAE for the enterprise web application we're developing.

[google-appengine] __key__ problem.
Another newbie question I am afraid, I am trying to use the ID/Name
field in my application, but having some problems.
I have the following query:
locations = db.GqlQuery(SELECT * FROM Location ORDER BY __key__
DESC LIMIT 10)
template_values = {
'greetings': locations,
}
And I am trying to use that field in my application like this:
{{ greeting.__key__ }}
{{ greeting.xpos }} etc
Everything is working, except for when I try to include the __key__
field, what am I doing wrong?

I know about taxes (http://code.google.com/intl/fr/appengine/docs/ billing.html#A_Note_About_Taxes), but here the gap between the GAE price and the Bank price is too big : 92% is only taxes. I think billing needs to be changed/adapted asap in several ways to reduce the taxes part : 1 - add new currencies (Euro, etc,...) 2 - do not charge weekly but monthly. About this, I think it is not really logical to charge weekly. Most services charge weekly and for example, if you use Google Adsense to pay you GAE site : Adsense will pay monthly. Else add an option (weekly/monthly) 3 - Do not charge under a certain amount ($1 or more) 4 - Add a credit system. For example, I credit my account with 50€, then GAE/Chekout use this money I know that banks need money ;), but here, I think this is very bad for users and GAE if it doesn't change and particularly for small project from non US users.

[google-appengine] Chrome display issue
I wrote a GWT app using the Eclipse IDE plugin. The app has a form dialog that includes a TextArea widget. User entered data in the TextArea widget is persisted from the form and later displayed in a Label widget. The data 'appear' to be missing newline characters showing one big concatenated string. I printed out the byte representation of the persisted data and the newline characters are there. This only happens in the Chrome browser and the G1 Android browser. Unfortunately these are my target web browsers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Random HTTP 500 errors
Since i am not able to find any real issues with my code, i want to check with all appengine developers if their apps also throw up random HTTP 500 - Internal Server Error. In my case this is happening mostly where front-end template related code is involved. To reiterate the issue, quite a few times, when a user accesses the site via browser(FF, IE, Chrome, Safari) the page fails to load. However if user refreshes, the same page loads just fine. If i look at the logs, there are no mentions in the Error log. In the Request log, only thing found is information about the request, but no errors. Also, for almost all these pages, they serve content from memcache, which means datastore calls are kept to minimum. If anyone else has seen these kind of errors, please let me know if you found a workaround.

[google-appengine] Re: How can I read a standard openssl private key with PyCrypto and decrypt with it?
Hi Tim,
Would you be open to using tlslite? I've had good experience with it so far,
so if you are looking to get up and running quickly this example might help
http://code.google.com/p/gdata-python-client/source/browse/trunk/src/gdata/gauth.py#378
from tlslite.utils import keyfactory
private_key = keyfactory.parsePrivateKey(rsa_key)
signed = private_key.hashAndSign(data)
Thank you,
Jeff

I can't figure out is how to use PyCrypto.RSA.construct with it
to decrypt something. This works however:
from M2Crypto import RSA
priv_key = RSA.load_key('private.key', get_password)
decrypted_key = priv_key.private_decrypt(base64.b64decode(enc_key),
RSA.pkcs1

I am sure there is a way to do this with PyCrypto, anyone know how to
do it?

[google-appengine] facebook
i see the libs for php are already a point of interest so i wont need to add to that so i would just like to add a question about google supporting 3rd party libs like facebook and myspace or other major brands. my problem is i am on a path to using google api to managing content via google products like picasa and google docs and from what i understand i could serve entire sites from this engine by pointing to an url. well if this is true then it doesnt matter that the net is evolving faster then hosting co's are willing to keep up with(Lazy). google i think recognized this and did something about it. this still leaves the rest of the major brands with no supporting host or very few, they dont provide and probably are not capable of doing something like this. so will google support 3rd party libs down the road? is there another way around it. already all other email sucks when stood against gmail, add to that the fact that my host might as well be dos without new libs to keep up means i and a lot of folks are going to be in search of ways to keep pace despite the lack of model shown by hosting co's. can google, will google HELP. the lack of response i get on the forums makes me doubt, yet the superior product google produces makes me drewl at the thought. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Questions about the preferred way to handle multiple apps/accounts
We have built an app that allows a web site to move portions of their web site to Google AppEngine, with minimal configuration on their part. This is great for WordPress, and Movable type users who would like to move their images off site, but don't want to mess with their CMS. Think of it like s3 for image hosting light, or Akamai site proxying made cheap. My Question is, should each user of our app software have their own account for the deployment, or should we have multiple accounts we use to set up their accounts, or should we have one account and request more accounts every time we reach our App Quota? The latter would be the easiest for us as we wouldn't have to log in and out to upgrade or monitor our clients health, but if we sell as many copies as it looks like we are going to, I didn't want to pick a method that would not be the one Google wanted us to use.

[google-appengine] Putting Entities With Unique Constraints
Ran into a gotcha with my App today. I have implemented a User Model that has a couple of properties (facebook id and email address) that need to be unique across all User instances in the datastore. I implemented my own get_or_insert method that I run in a transaction. The get_or_insert method queries for either or both properties (fb uid or email) depending on parameters. If no object is found, a new one is inserted. My problem is there are cases where I want to do this for dozens of items in one request. The execution time I am seeing on the queries to check for existing items is prohibitively long. I am getting time outs when trying to process (get_or_insert) 100 items. I've experiemented with not using the transaction just to see if it would change the overall time. The impact was minimal. I've experiemented with doing bulk puts (putting a list of Model instances at once). This was great, but does not help as the queries are still needed to see if the items exist and to try to enforce uniqueness. Any one have any advice on an alternative approach that may work? I've thought about doing it asynchronously using the task queue, but that does not work with the user experience and flow of the application. Right now, I think a new approach is needed that avoids creating the objects at this point in the application flow. Here's the code that implements the get_or_insert and is run as a transaction: def _run_user_get_or_insert(q_by_email, q_by_fbuid, confirm_user, new_user): user = None updated = False if q_by_email: user = q_by_email.get() if not user: if q_by_fbuid: user = q_by_fbuid.get() if not user: user = new_user updated = True if confirm_user and not user.is_confirmed: user.is_confirmed = True updated = True if updated: user.put() return user Running on app engine, it takes ~16s to create 100 new users.
