[appengine-java] Development server requires custom indexes for inequality filters on keys
I was trying to do an inequality query on the Keys of an entity on the development server and received the following error: SEVERE: QUERY ERROR: com.google.appengine.api.datastore.DatastoreNeedIndexException: Query com.google.appengine.api.datastore.dev.LocalCompositeIndexManager $indexcomponentsonlyqu...@203ede49 requires the following index: datastore-index kind=NewsStoryServer ancestor=false source=manual property name=categories direction=asc/ property name=__key__ direction=asc/ /datastore-index The App Engine docs specify that inequality filters on keys and equality filters on other properties are supported by a default index (http://code.google.com/appengine/docs/java/datastore/ queriesandindexes.html#Defining_Indexes_With_Configuration) and it does work when I run in on AppEngine so it seems to be a Development server problem. Anyone else encounter this problem? James -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Eventually consistent reads and JDO
Hi all, Thanks for all new new features in 1.3.2! I was just wondering if it is possible to use the ReadPolicy.Consistency.EVENTUAL feature and still use the JDO interface. I am currently getting a PersistenceManager with: JDOHelper.getPersistenceManagerFactory(transactions- optional); Is there a way to tell the PersistenceManager to tell the datastore to accept eventually consistent reads? Most of my app can handle stale data, and any performance improvement would be great!

[appengine-java] Slow JAXB context initialization
Hi ! I have a problem with JAXB context initialization. After some of my model optimization the local development server takes to start up (JAXBContext initialization included) about 7 seconds (as unit test it takes 1 second only. My CPU 3.06 GHz Core 2 Duo - GAE 1.3.1). However, on App Engine it takes still more than 30s quota limit thus I'm not able to start it up. It's about 300+ java classes. I have setup the following as well property name=com.sun.xml.bind.v2.runtime.JAXBContextImpl.fastBoot value=true/ I locally did some measurement by profiler and the most expensive operation was the following: com.google.appengine.tools.development.DevAppServerFactory CustomSecurityManager.checkPermission(java.security.Permission) Total Time: 4 973 ms Calls: 86332 Could you, please, point me out where could be a problem?

[appengine-java] JPA: Query contains stale data (bug or future)?
Hello.
I'm using JPA support for managing the App Engine datastore.
And I've got some problems.
I've got an entity Container than contains entities Item(s).
Here is my actions.
I starts transaction then updates entity then flush updates to
database.
Than I gets all entities Item(s) for a container which contains my
updated Item.
But the list of retrieved items contains Item that does not have my
changes.
What is wrong with my code???

[appengine-java] Grails, Spring, and Thread Issue
Hi all - I am aware of the thread policies in GAE, but I am not sure what changed, when I recently deployed a grails app (which i've done in the past w\out issues), and now all of a sudden it appears that Spring (as a part of grails) is attempting register a bean which requires threading, and then of course throws the access exception.

retrieving a class that contains multiple properties of the same type,

With the allowMultipleRelationsOfSameType= true, the persistence is
OK, but the retrieve returns duplicate value for properties of the
same type (even though it was saved with different values for x y).
Is there a fix planned for this?

[appengine-java] JPA query contains stale data.
Hello.
I'm using JPA for the App Engine datastore.
And I've got some problems.
I've got an entity Container than contains entities Item(s).
Here is my actions.
I start transaction then update entity then flush updates to database.
Then I get all entities of class Item(s) for a container which
contains my updated Item.
But the list of retrieved items contains Item that does not have my
changes.
What is wrong with my code???
I've modelled this problem. (see code)
@Entity
public class Container implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
@OneToMany(mappedBy = container, fetch = FetchType.LAZY)
private ListItem items = new ArrayListItem();
public void setKey(Key key) {
this.key = key;
}
public Key getKey() {
return key;
}
public void setItems(ListItem items) {
this.items = items;
}
public ListItem getItems() {
return items;
}
}
@Entity
public class Item implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
@ManyToOne(fetch = FetchType.LAZY)
private Container container;
@Column
private String value;
public void setKey(Key key) {
this.key = key;
}
public Key getKey() {
return key;
}
public void setContainer(Container container) {
this.container = container;
}
public Container getContainer() {
return container;
}
public void setValue(String value) {
this.value = value;
}
public String getValue() {
return value;
}
@Override
public String toString() {
return Item [key= + key + , value= + value + ];
}
}
@Service(TestLocalService)
public class LocalService {
protected final Log logger = LogFactory.getLog(getClass());
public Key createContainer() {
em.getTransaction().begin();
Container container = new Container();
em.persist(container);
em.flush();
logger.fatal(new container + container.getKey());
em.getTransaction().commit();
return container.getKey();
}
public Key generateItems(Key containerKey) {
em.getTransaction().begin();
Container container = em.find(Container.class, containerKey);
Key key = null;
for (int i = 0; i 5; i++) {
Item item = new Item();
item.setContainer(container);
item.setValue(Integer.toString(i));
em.persist(item);
em.flush();
key = item.getKey();
logger.fatal(new item + item);
}
em.getTransaction().commit();
return key;
}
public void changeItems(Key containerKey, Key itemKey) {
em.getTransaction().begin();
Container container = em.find(Container.class, containerKey);
Item changedItem = em.find(Item.class, itemKey);
changedItem.setValue(xxx); //

PROBLEM HERE
em.flush();

[appengine-java] Objectify - Twig - SimpleDS articles
Hi all. I recently decided to migrate away from JDO to one of the third party datastore frameworks. At first I had only heard about objectify, but after some further digging I found out about 5 other frameworks as well (Twig, SimpleDS, siena, slim3, cloud2db). I was only interested in simple wrapper frameworks that acted as a convenience layer above the AppEngine low-level API. I _want_ the framework to expose the true nature of the datastore, but at the same time relieve the developer of the tedious tasks that's involved when working with the low-level API directly. It is much easier to work with the AppEngine datastore when its concepts, features, constraints and limitations are exposed directly. You can read more about the reasons for this in the article. This left me with objectify, Twig and SimpleDS. (siena and cloud2db are multi-platform and slim3 is more than just a datastore framework) I spent some time researching these when I got the idea to write an article about them. I contacted the authors for each framework and asked if they would be interested in participating. Passionate as they are, they agreed :-). Thanks to Jeff Schnitzer (objectify), John Patterson (Twig) and Ignacio Coloma (SimpleDS) for this. The goal is to publish two articles; one interview with the authors, and one where I solve some typical scenario with each framework. The interview article has now been published and can be found at http://borglin.net/gwt-project/?page_id=604 . The code example article will be posted sometime in the upcoming two weeks. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

It does not matter the url to the servlet i use to work with de keys

[appengine-java] Re: Workaround for Spring transactions throw GenericSignatureFormatError
Hey, Thomas, Thanks very much for working on this! I think a lot of people want Spring transactions to work in GAE. What does your fix do? Or why does it work? It looks like you're just creating a proxy that passes the invocation along. For example, my jdo-context.xml is below. Is your new bean tied to a transaction manager somehow like the one below? Does having the proxy prevent the AOP engine from throwing the exception?

Hi all,

I do :

http://www.google.com/calendar/feeds/default/private/full;, false, true);
response.sendRedirect(authSubUrl);

Re: [appengine-java] Re: Update to GAE/J 1.3.2 - Project in Eclipse broken
Hi Moritz,
Could you try the following:
- In your project properties, could you see what the App Engine SDK is set
to (right-click project Properties Google App Engine). Does it show
an error on this page? If you click the Configure SDKs button, what is the
path for the SDK?
- In your project properties, can you go to Java Build Path , then Libraries
tab, and see if there are any leftover JARs on your classpath? If there
are, could you take a screenshot of that dialog (hopefully tall enough so
all the entries are visible)?
Thanks,
jason

At first I had only heard about objectify, but after some further digging I found out about 5 other frameworks as well (Twig, SimpleDS, siena, slim3, cloud2db). I was only interested in simple wrapper frameworks that acted as a convenience layer above the AppEngine low-level API. I _want_ the framework to expose the true nature of the datastore, but at the same time relieve the developer of the tedious tasks that's involved when working with the low-level API directly. It is much easier to work with the AppEngine datastore when its concepts, features, constraints and limitations are exposed directly. You can read more about the reasons for this in the article. This left me with objectify, Twig and SimpleDS. (siena and cloud2db are multi-platform and slim3 is more than just a datastore framework) I spent some time researching these when I got the idea to write an article about them. I contacted the authors for each framework and asked if they would be interested in participating. Passionate as they are, they agreed :-). Thanks to Jeff Schnitzer (objectify), John Patterson (Twig) and Ignacio Coloma (SimpleDS) for this. The goal is to publish two articles; one interview with the authors, and one where I solve some typical scenario with each framework. The interview article has now been published and can be found athttp://borglin.net/gwt-project/?page_id=604.

Re: [appengine-java] Re: How to get IP address of Appengine running my java servlet page
It seems quite unlikely that GAE appservers are going to have public IP addresses. Even if you can get the IP address of the host (and I suspect this is impossible), it's going to be a private address. The best you will probably be able to do is get the NATed apparent address of the URLFetch servers. Make a URLFetch request to a server you run somewhere and check the source IP address in the logs. This isn't necessarily a good piece of data, though. For one, this is simply going to be an outbound public IP. The request could have been routed around the world through Google's private network before it found an outbound node. For another, it's going to come from the URLFetch service... and there is no guarantee that the URLFetch server is the same box (or even located anywhere near) the box your app runs on. It's an opaque system - deliberately so.

Re: [appengine-java] Looking to brush-up on my Java
Having *not* done JEE in a while may actually be a boon, as you would have had to unlearn a few concepts coming from a relational persistence, stateful servlets world to one that is not. If you work your way through the tutorial and App Engine documentation, your prior Java experience should be more than enough to start building, so as long as you don't try to jump in and use frameworks you aren't familiar with from the get-go. As far as specific App Engine questions go: search the groups and StackOverflow, and if you don't find your answer you can always ask.

Re: [appengine-java] Charging Application Users for Data Storage

In the (however unlikely!) event that my app becomes popular and this threshold is significantly exceeded I would like to pass on the cost by charging users based on how much data they store.

Re: [appengine-java] Re: Why should app startup times be a problem.
JohnJ, The way I see it, you just need to pay for one warmed instance. I've measured that one instance is enough to handle 30 requests per second. Trying to execute more requests than that immediatly triggers the loading of a new instance and so far some of the requests fail. Therefore, If you are using 1 instance in real traffic (max 30 requests per second), you only need another one when you reach 31 requests per second, so that new instance in theory would all you need warmed (unless you think you will jump from one instance to 3 instance from one second to the next). Assuming all requests end before one second, and assuming the time to load an instance to be kept warmed is a few seconds, you only need 1 warmed instance added to the instances you are actually using (which should be number of requests per second / 30).

[appengine-java] Java Tasks
I have a simple Java task that simply checks to see if it needs to send an email email sent flag =N. It is taking in excess of 6604 milliseconds to execute.

Re: [appengine-java] Re: Why should app startup times be a problem.
Warmed instances make absolutely no sense on the GAE! It's supposed to be an invisible, infinite, platform without the notion of ram, cpu's, drives or instances - it goes completely against the heart and soul of the project. That just makes us an Amazon. It's boggled my mind from day 1 why instances aren't loaded in the background. I always assumed it would be addressed shortly - but instead we've decided to completely break the model. Why? I hate to over-simply, but it really doesn't seem like it's that difficult to make sure requests only go to ready/warm servers. I bet you could even solve 99% of the cases by simply waiting 3 minutes before serving a request. Of course, I still love the GAE :) Baz -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Why should app startup times be a problem.
It's boggled my mind from day 1 why instances aren't loaded in the background. I always assumed it would be addressed What is difficult to understand? 1 server has X resources warmed instanced require Y resources X - YN = resources left over for the server to fulfill requests. By reducing N (the number of warmed instances), you can increase the capacity to fulfill actual requests. By allowing us to pay for our own N, Google can presumably increase the capacity of each server or can increase the number of servers. I can see how it can cost Google to have unused apps loaded and ready to immediately serve. Can't you. I don't see what the difficulty understanding is.

http://www.google.com/calendar/feeds/default/private/full;, false, true);
response.sendRedirect(authSubUrl);

if(oneTimeUseToken != null){
String sessionToken =
AuthSubUtil.exchangeForSessionToken(oneTimeUseToken, null);

// redirect to the page using google services

The problem is that when later I do:

site.setLoggedIn(true);
}else{
site.setNickName(Guest);

The Problem is that the URL takes me to the custom Google Apps Login

i.e for a domain xyz.com - it takes me to google apps login page for
xyz.com.
Do I need to do something different??

Does a string take variable length or always 500bytes? Does a blob use just its actual size? Does the key count towards the 1MB limit and how much? What is the most efficient way in terms of #bytes to have a property value which points at another entity.

[google-appengine] I want more scalability.
My application needs more than 50 request/second. I found some warning logs, that returns 500 error page. Error log says: Request was aborted after waiting too long to attempt to service your request. Most likely, this indicates that you have reached your simultaneous dynamic request limit. This is almost always due to excessively high latency in your app. Please see http://code.google.com/appengine/docs/quotas.html for more details. The error has 0cpu_ms, 0api_cpu_ms, but it cost just 1ms to return the page with 500 error. I post this thread, but no solution. http://groups.google.com/group/google-appengine-python/browse_thread/thread/d0a9be3d880c3579 So I take a very simple test for scalability.

Result: * 10request/second test is good. * All request returns 200 page by 330ms.

Re: [google-appengine] Re: How to visit GAE apps in China, now it denied completely!
Hi, Dark-horse The Iceland Govt. in bankruptcy state does not has GFW. It surprise me that the severe economical situation of China in your description. Well, I don't think that here is the right place to make political or military arguments. Let's focus on the problem specific to your country. The GFW actually also enclosed an opportunity for you by locking the door up. Why not start your own business with TyphoonAE(Python) or AppScale (Java) in your country. The market of GAE-compatible service within the GFW is all yours. Haven't you find that how great it is. The people of China can access all the utilities and tools on the internet freely. All of the free lunch on the internet were not been blocked by the GFW provided that they do not annoy the China Govt. Whereas the websites (services) outside the China are not accessible by consumers in the so-called world largest market which behinds the GFW. No matter you care about your fellows' human rights or not, The GFW might become beneficial to your pocket with TyphoonAE and AppScale. See, what the Google done is good for the people who address to human rights as well as people who emphases on business profits. 2010/3/29 Dark-horse shenguoc...@gmail.com Hi everyone, First, thanks your guys for helping me to get through the GFW.

Re: [google-appengine] Re: How to visit GAE apps in China, now it denied completely!
Hello Dark-horse, I am a Chinese. I think it's useless to complaint here. Google has his faith, while Chinese gov has his rules. As we are unable to change either of two side, the only thing we can do is adapt ourself, keep pacing with the advanced techs, and figure out some solution to handle current situation. Good news is GAE apps seems not blocked entirely, I can access my app in company, my friend told me he can access my app from home, and most apps in google app gallery are still available in China. Although still some websites are denied. But I never heard any news about China gov will block Google App or Google cancel his app market in China. I think it's just some websites are blocked temporary due to some sensitive words. I agree that the condition for Chinese developers is not optimistic, but it's really meaningless to complaint here.

[google-appengine] html5 cache ... is it working?
Can someone show how to use HTML5 cache with google app engine python? I have gone through the tutorials and have an app.yaml that looks like this application: secret-valentine version: 1 runtime: python api_version: 1 handlers: - url: /cache.manifest mime_type: text/cache-manifest static_files: cache.manifest upload: cache.manifest - url: /static static_dir: static - url: .* script: secret-valentine.py login: required The cache.manifest file looks like this: # v9 CACHE MANIFEST /static/ext-all.js static/ext-all.js ext-all.js NETWORK: FALLBACK: And the browser is downloading the cache.manifest file as a manifest file. The problem is that the browser is always going to the server to get the ext-all.js file. I want it to get the file out of its local cache. One thing I notice in the logs is that the call to cache.manifest always comes after the call to ex-all.js. Even when I put the ext- all.js script tag at the very bottom of the page. I saw this http://code.google.com/p/googleappengine/issues/detail?id=1050 and took a close look at this page http://iui-js.appspot.com/samples/music/music.html#_home using firebug and I see his cache files are also being requested. (Unless firebug is wrong). Maybe I have the wrong expectations of html5 and you cannot utilize a local server? Anyone familiar with HTML5 cache?
