This is exactly the type of feedback we need in this forum to help us who are starting new projects to best decide on what APIs and designs to use. For example, if you could summarize your handling of this simple relation that is in ALL apps: Entity A and B are related to each other via C. So, A is 1-many with C and B is 1-many with C...so C is a many-to-many. Surely, you have this in your app. How do you compare your JDO implementation of these 3 Entities with your low- level API implementation? Perhaps you could include some simple code to illustrate your points. Seems I've only seen very basic examples like Hello World.

[appengine-java] Re: My recommendation: Use Low-Level API instead of JDO/JPA
The best example I could find was:
// Get a handle on the datastore itself
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
// Lookup data by known key name
Entity userEntity = datastore.get(KeyFactory.createKey(UserInfo,
email));
// Or perform a query
Query query = new Query(Task, userEntity);
query.addFilter(dueDate, Query.FilterOperator.LESS_THAN, today);
for (Entity taskEntity : datastore.prepare(query).asIterable()) {
if (done.equals(taskEntity.getProperty(status))) {
datastore.delete(taskEntity);
} else {
taskEntity.setProperty(status, overdue);
datastore.put(taskEntity);
}
But is 1 datastore factory ok or should I create different ones?

I would like documentation about low-level API programming.The API is

For example, It is not necessary to close the DatastoreService after
using? It's very confortable but it seems odd.

[appengine-java] Re: How to view log file locally?
It's not the question if it's worth learning Maven. It's the question how to read log files locally. Would it be possible to run the Google admin console locally and read the log files?

So althought I'll have that in mind, I'd rather see whether there's another easier way to solve this. Any other ideas? Esteban Rusty Wright escribió: This is one of those places where maven can really help. With maven I think what I would do is create 2 log configuration files for log4j (although I prefer logback and slf4j, but that's a separate topic), one with local logging to a file and the console, and one with logging only to the console. Then set up maven profiles, call them dev and prod, and when you build, maven's filtering capabilities rewrite whatever config file you're using that specifies the log config file. (It doesn't rewrite it in place, but before it puts it in the war file.) If you don't have a config file that specifies the log config file I'm pretty sure you can have maven use the appropriate log config file via the profile you select when you build. In this GAE development environment you may not even need all of that. With maven you have 2 trees, main, where the production code and resources live, and test, where your unit and integration test code lives, and their resources. Notice how each has their own resources directory; that's where I put my log4j config files, one for main, and one for test. When I do a build maven only includes the stuff from the tree named main; the tree test never sees the light of day, as it were. http://www.sonatype.com/documentation/books http://www.maestrodev.com/better-build-maven Marcel Overdijk wrote: Esteban, that's indeed THE question !

My application contains approx 5000 images related to teams (each team has it's own logo). I was thinking about serving them from a jar file. I'm wondering if it would be better to serve them from the datastore and possible store/retrieve most used logos in memcache. What would a better solution in terms of performance and billing? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

OK thanks,
To be honest - looking at other thread - I think Google is not always
that fast in responding.
But maybe this time we get a response.
I must admit that I'm a little bit spoiled by Grails user list in
which we get almost instant answers ;-)

The proposed solution will only substitute the EL engine, which would

[appengine-java] Re: --enable_jar_splitting
Hi Don, The jar contains a lot of images so it doesn't matter that files need to be in the same - splitted - jar. In fact the --enable_jar_splitting sounds perfect for me as I don't have to do the work myself: just maintain one single jar with the images, and let gae deployment split them up if necessarily. How can I enable --enable_jar_splitting for my app? I'm deploying my app using the eclipse plugin. On Dec 22, 6:17 pm, Don Schwarz schwa...@google.com wrote: I would recommend that you simply split it into arbitrary pieces yourself. --enable_jar_splitting is a workaround to have the deployment tool do this itself, but this can cause problems with some libraries (e.g. if it expects to find a resource file and a class file in the exact same jar) so I would recommend trying it manually yourself.

[appengine-java] Re: GAE roadmap for 2010
I agree a new 2010 roadmap would be really needed. Current roadmap page only contains: 1. Support for mapping operations across datasets 2. Cursors for continuing results of Datastore queries past the 1000 entity limit 3. Alerting system for exceptions in your application 4. Datastore dump and restore facility In which I think 2. and 4. are really great! But I don't think that will be all which will be released in 2010... (or at least I hope not). A clear vision where Google is going with the app engine platform is really needed specially to sell it to businesses. Think about SLA's, keeping instances warm, etc. Further more I/m wondering if Google is planning to support more languages in 2010.

In my test code I can see entitymanager was not injected yet, but I think that's another mis configuration on my side.

[appengine-java] Re: Objectify-Appengine, a typesafe data persistence tier for App Engine
This really looks great!
On 13 jan, 18:28, Jeff Schnitzer j...@infohazard.org wrote:
http://code.google.com/p/objectify-appengine/
I probably should have called this project Goldilocks, because it's
a little bit how I feel. Despite being a longtime Hibernate user
(since the 1.0 days), the JDO/JPA abstraction just doesn't make me
happy on appengine - it's too big, too complicated, and too far
removed from the nature of the beast. The low-level API has an
elegant simplicity, but it lacks type safety. I tried the
alternatives - Siena, Twig, SimpleDS, and Slim3. There are good
things I can say about these projects but none were just right for
me.
So, in time-honored tradition, I wrote my own and now I'm offering it
to the world. Here is what just right means to me. Maybe it's just
right for you too:
* An interface that reflects the four fundamental datastore
operations - get, put, delete, query - including their batch variants.
* Persisting real typed POJO classes - no detaching, no lifecycle,
serialize at will.
* Keys inObjectifyare generified and typed. Instead of Key you use
OKeyMyEntity. This generic typing extends to OQueryMyEntity and
OPreparedQueryMyEntity.
* Because Kind ~= POJO Class, Key should not be used for an object's
id. The object's id and its (optional) parent plus the class is
complete; an entity that has a Key identifier contains a redundant
(and potentially inaccurate) kind. Nevertheless, a Key is necessary
for loading entities or referencing entities, and forms a fundamental
part of the API. This dichotomy is something I don't feel had been
done right yet.
* Queries are modeled after the human-friendly GAE/Python Query
class: query.filter(field , 123).sort(-field). You can filter
and sort on id fields almost as if they are normal properties.
* Transactional behavior is contained within theObjectifyinterface
(analogous to DatastoreService) instance rather than a thread local.
You can easily have several transactions (or nontransactional
sessions) running concurrently.
* You can use your entities in GWT-RPC without modification - even
with OKey fields. They're just POJOs and they serialize fine.
* Builtin facilities to help with renaming fields and transforming
data during schema migration.
* Configurable automatic retries for DatastoreTimeoutExceptions
(finally get rid of the 0.1% trickle of failures!).
* Zero external dependencies - no Spring, no Guice, not even a logger
(it just wasn't necessary). Just one lonely 36K jar.
*Objectifywill work nicely with your DI framework. Static
singletons are not required.
* Negligible impact on cold start time.
* Thorough unit test suite.
* Simple, easy-to-read, well-documented code. Not counting the
tests, there's actually only ten source files plus three annotations.
About 2,000 lines including whitespace and javadocs.
There is ample documentation athttp://code.google.com/p/objectify-appengine/,
but some code examples
should make this clear:
Basic operations:
@Entity
class Car {
�...@id String vin; // Can be Long, long, or String
String color;
Date registered;
}
Objectifyofy = ObjectifyService.begin();
ofy.put(new Car(123123, red));
Car c = ofy.get(Car.class, 123123);
ofy.delete(c);
OQueryCar query = ObjectifyService.newQuery(Car.class);
query.filter(registered , lastYear).sort(color);
ListCar cars = ofy.prepare(query).asList();
Some more sophsticated examples:
@Entity
class Employee {
�...@id long id; // primitive long is never autogenerated
�...@parent OKeyCompany employer;
// field getting renamed
�...@oldname(boss) OKeyEmployee manager;
String firstName;
String lastName;
// we used to store fullName, now we store first and last separately
�...@oldname(fullName) public void oldWay(String fullName)
{
String[] split = fullName.split( );
firstName = split[0];
lastName = split[1];
}
}
Here's an example of interleaving a transactional session with a
nontransactional session:
ObjectifyofyNoTxn = ObjectifyService.begin();ObjectifyofyTxn =
ObjectifyService.beginTransaction();
try
{
Foo f = ofyTxn.get(Foo.class, k123);
Bar b = ofyNoTxn.get(f.barKey);
if (b.wantsUp())
f.increment();
else
f.decrement();
ofyTxn.put(f);
ofyTxn.getTxn().commit();}
finally
{
if (ofy.getTxn().isActive())
ofy.getTxn().rollback();
}
The full docs are here:
http://code.google.com/p/objectify-appengine/
What doesn't it do?
* It doesn't work with any datastore other than GAE.
* It doesn't manage relationships for you - if you want cascading
deletes, collection proxies, and all the advantages and disadvantages
of that - you want JDO/JPA. I find managing this myself pretty easy,
and well worth the transparency.
* No support yet for polymorphism. It won't

Re: [appengine-java] Re: Deferred Task with non default queue
Hi Gianni, If I understand correctly I can use the default handler for any deferred task and thus specifying the url is irrelevant. How would I send a 'deferred' Task to a specific queue? Like this? QueueFactory.getQueue(email- queue).add(TaskOptions.Builder.withPayload(newEmailTask(email))); This seems to work indeed as DeferredTaskContext.getCurrentRequest().getHeader(X-AppEngine- QueueName) prints out the 'email-queue'. So that's great.

What I see is that the retry parameters are not picked up (at least in Development server). I keeps trying (more than the 3 time retry limit) and the backoff seconds are also not used. I see the first 3 or 4 retries within 2 seconds or so, and interval starts increasing, nut 5 between each retry. Could it be that the queue.xml is not picked up or I did something wrong?

[appengine-java] Feelings about new pricing model
Today Google announced the new pricing model to be effective later this year (http://googleappengine.blogspot.com/2011/05/year-ahead-for- google-app-engine.html). I always like the pay per usage model compared to the pay per instance model. Because of this change by Google, other platforms - like VMware's CloudFoundry - might be on the same pricing level and offer more advantage as they are more flexible in terms of frameworks supported. I'm wondering how other developers feel about this change in pricing model. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Scheduler features and load time limitations

Yes might be, but frameworks like Grails need a longer startup time. It does not matter for any application server nor cloud provider except GAE. That's why I'm asking about future working of scheduler. Further, if I keep up enough instances I would not bother the startup time at all...

[appengine-java] Re: Scheduler features and load time limitations
Honestly I don't know what the current startup time for Grails on GAE would be now. Also depending on what plugins installed etc. Current version does not even work on GAE. I was thinking about trying it out again but remembered the 30s limit I hit some time ago. So I asked this question on the forum to see if it makes any sense investing the time, or just continue with my Spring MVC app which runs fine.

[appengine-java] Re: Scheduler features and load time limitations
btw: I was able to run latest Grails 2.0.M1 on GAE infrastructure. Request that cause a instance to be loaded take 29 - 31s and sometimes cause a HardDeadlineExceededError. After instance is loaded requests are very fast, until they are ceased down by GAE scheduler. I have no concern with the long startup time, as with Always On it should not be a problem. But that brings me back to one of my original questions: 2) How smart will the scheduler be to startup new instances? Will it for example take into account the avg load time of previously started instances?

I'm wondering what the options are for starting up the DevAppServer manually. I read about the KickStart, DevAppServerMain etc but this not satisify my needs. I more or less looking to possibilities to use something like: org.mortbay.jetty.webapp.WebAppContext.setDescriptor(String contentWebXml) To interact with the underlying Jetty container itself, or to configure it manually. This might be awkward question but what I'm looking for is to integrate the DevAppServer with Grails just like Grails does this for Jetty and Tomcat. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
