[appengine-java] Re: 1.3.8 Console Logging Issue
Dropping default log level (.level) to TRACE, INFO or FINEST doesn't fix the problem. log.info (with default INFO level) used to work before 1.3.8 upgrade and doesn't work after the upgrade.

[appengine-java] Re: Does ImageService support join image?
I think what you are looking for is "Composite". Look at the javadoc
of the image service and service factory, there's a way to create
composite and there's a function to take a list of composites to
compose a single image.

[appengine-java] 500 Errors on blobstore upload, perhaps related to oauth?
Hello, I have yet to get the blobstore functioning correctly in my app. My code works in development, but not in production. I use the built-in oauth support and have an installed app connecting to the GAE app. The installed app requests an upload URL from an endpoint that is secured by oauth, and I was surprised to see that BlobStoreService.CreateUploadURL() produces a URL that has all the oauth stuff in it. Here is the URL it produced: http://MYAPPo.appspot.com/_ah/upload/?oauth_token=1%2FTRaFrr7-6m5xhHfTNxEWro&oauth_consumer_key=anonymous&oauth_nonce=jp3RjU8Q&oauth_signature_method=HMAC-SHA1&oauth_signature=%2BArexxxQfQrcg%3D&oauth_version=1.0&oauth_timestamp=1288724065/AMmfu6ZXzzxvVnfoJ_K5kHbgI-uk87Jp_0AV140OVlmUURx8x8qJCeP_GqXSrl5cm3-WtXObp8hQ8DxLBNUaYATNBgt3DyA_0PLeSByXaA-g5FvxLzpCMj/' When my installed app then tried to POST to this URL, it gets a 500. The Blobstore then proceeds to call my GAE app with the URL I supplied to CreateUploadURL(), and passes along all the parameters that the client app sent to the Blobstore, but (as expected) without a Blobstore key. I don't see any blobs in the blob viewer. I wonder if the oauth code is somehow at fault here, but other than that I don't really know where to start diagnosing this.

[appengine-java] Debugging against production datastore?
Hi, I'm looking for a method to access the datastore remotly, solving this would allow me to debug my development code using production data.

[appengine-java] Analytics and App Engine / GWT Timouts
Hi all, I'm getting an analytics feed through the API and it all works beautifully as a Java application. But when I try to get it to work on an AppEngine / GWT application I get timeout errors. Specifically the following: java.io.IOException: Timeout while fetching: https://www.google.com/analytics/feeds/data?max-results=50&start-date=2010-10-02&end-date=2010-11-02&metrics=ga%3Avisitors%2Cga%3Avisits%2Cga%3AnewVisits%2Cga%3Apageviews%2Cga%3Abounces%2Cga%3AtimeOnSite&ids=ga%xx I am setting the connection and read timouts like this: analyticsService.setConnectTimeout(3); analyticsService.setReadTimeout(3); but the error doesn't go away. Researching this I believe this is caused by the app engine URLFetch timeout, which defaults to 5 seconds. (http:// code.google.com/appengine/docs/java/urlfetch/overview.html#Requests) The fetch from the analytics service takes in my case some 30 seconds, for several table_ids, so raising the timeout to 10 seconds won't help.

[appengine-java] Re: Help please! JPA Parser error!
You might try the following.
Query query = manager.createQuery("select u from User u where u.name =
's...@some.com'");
// note use of identification variable & single quotes
User u = (User) query.getSingleResult();
Or, use a query parameter to avoid having to deal with quoting and/or
string concatenation (which subjects you to injection attacks), like
the following.
Query query = manager.createQuery("select u from User u where u.name
= :name");
query.setParameter("name", "s...@some.com");
query.getSingleResult("s...@some.com");
User u = (User) query.getSingleResult();

[appengine-java] Mapper & Blobstore bytes read limit
I've been testing Ikai's bulkload mapper (see url below) with a pretty big csv file (200 Mb). It works great, and I encourage most of you to consider implementing this for entity uploads. Yet, I do face one last issue with an unexpected quota : blobstore bytes read. This quota cannot be tuned via the billing settings, and it's not clear whether it limits the speed of my process or not when it's reached. See ? Yep, it's a lot of bytes readŠ Could someone confirm that the blob csv file is *NOT* fully fetched each time the mapper iterates on a new line ?

[appengine-java] Re: Convert JDO/JPA POJO to a Datastore Entity
Generally speaking, what Didier says is entirely true. Mappings are, for my experience, done as follows *Entity name is the class name without package extension *Properties names are field names *Property kind is mapped according to this page http://code.google.com/appengine/docs/java/datastore/dataclasses.html#Core_Value_Types If you want to investigate how your entities are mapped you can use the Local Testing utilities http://code.google.com/appengine/docs/java/tools/localunittesting.html Just do something like this in a test class: *Persist the object using JDO *Obtain the datastore service mock thru the testing tools *Query the datastore for the kind you just created, then you can iterate on entity property. The main disadvantage in guessing the mapping is that you lose type checks: all entities kinds are of one of the core value types, so you'll need to explicitly convert it from/to your POJO field types. This is closely related to what Didier emphasizes. So I too advise you to investigate it as a testing practice, but do not rely on it in production.

[appengine-java] Phantom JPA entity
We have a simple Java web app - using JPA with 2nd level cache enabled. We're running 2 instances of this app simultaneously -- test env and real production. Atm the two instances don't diff much; both use the same persistence- unit name, same cache name, same entities, ... OK, the application name in the app engine (appengone- web.xml#application) is of course different. org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider When running our app in production, we sometimes get "phantom" entity results. e.g. we see an entity result that matches (is equal to) some result we put in out test app instance. Searching for this, let me to this old post: * http://stackoverflow.com/questions/3033286/appengine-datastore-phantom-entity-inconsistent-state which might be similar. Is this a know issue? Or are we missing something to do a proper split? e.g. too much of the "same" stuff -- PU name, cache name, ...?

[appengine-java] JPA/JDO key with parent and autogenerated long id
I have a simple class where the key needs a Parent and auto generated

I am not sure hot to implement this with JPA/JDO, here is a hack I
tried:
@Entity
public class Account {
@Id
private Key key;
..
}
Account account = new Account();
account.setKey(DatastoreServiceFactory.getDatastoreService().allocateIds(parent.getKey(),
Account.class.getSimpleName(), 1).getStart());
em.persist(account);
This seems to work, but I am wondering if there is a more elegant way?

[appengine-java] Re: Convert JDO/JPA POJO to a Datastore Entity
Hi George, What you are looking for is anyway possible: the JDO/JPA entities are stored in datastore as Entities eventually. You'll have to figure out (i.e reverse engineer) the mapping between the pojo annotations and the corresponding ds structures. I see 1 big issue: the mapping that you will figure out has no guarantee from Google, it can change any time and you may need some time to figure out when it changes with risks for the integrity of your data. I would either work at high or low level on a given piece of data but not simultaneously if you can't have "guarantees". regards didier On Nov 2, 8:58 am, George Moschovitis wrote: > I know about Objectify but I would like to use a standard solution > like JPA/JDO. > Even if it is (currently) less efficient than custom solutions. > > -g. > > On Nov 1, 12:32 pm, Didier Durand wrote: > > > Hi George, > > > Not a direct answer to your question, but if you're looking for > > something "lighter" than JDO/JPA, I would encourage you to have a look > > at Objectify: it's much closer to DS api than JPA/JDO (and much > > simpler and more efficient...) but still provides a good level of > > abstraction for efficient programming. > > > Something that could be tried (as Objectify uses some JPA annotation) > > is to remap JPA entities onto Objectify entities but it very much > > depends on your level of sophistication in the use of JPA. > > > regards > > > didier > > > On Oct 31, 10:08 pm, George Moschovitis > > > wrote: > > > Is there a way to convert a JDO/JPA POJO to the corresponding > > > Datastore Entity?
