[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. Are tasks executed with a much lower priority? When I moved my start time to15 minutes later I was a least able to get rid of the most of the HTTP 500 errors caused by exceeding the simultaneous dynamic request limit. -- 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.
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.

Hi,
I was not able to have them reproduce behavior though I tried a
little.
(It was possible to execute it normally).
Can post do you the source code further?
I want to confirm behavior.
Or, the environment might be a cause.
thank.
Come on!
Anyone, anything?
Thanks.

Hi all,
I am facing a strange problem in with my app in GAE and I can't seem
to figure it up by myself, so I hope you'll help me.. Here we are:
I do :
[code]
String authSubUrl = AuthSubUtil.getRequestUrl(nextUrl,
http://www.google.com/calendar/feeds/default/private/full;, false, true);
response.sendRedirect(authSubUrl);
[/code]
in my servlet in order to get an auth subtoken. And the servlet at
nextUrl does:
[code]
String oneTimeUseToken =
AuthSubUtil.getTokenFromReply(request.getQueryString());
if(oneTimeUseToken != null){
String sessionToken =
AuthSubUtil.exchangeForSessionToken(oneTimeUseToken, null);
// persist the sessiontoken}
// redirect to the page using google services
[/code]
in order to retrieve and persist the sessiontokenalong with other
user information.
The problem is that when later I do:
[code]
URL feedUrl = new URL(http://www.google.com/calendar/feeds/default/
private/full);
CalendarQuery myQuery = new CalendarQuery(feedUrl);
CalendarService calendarService = new CalendarService(some-app-
name);
calendarService.setAuthSubToken(currentUser.authSubToken, null);
CalendarEventFeed resultFeed = calendarService.query(myQuery,
CalendarEventFeed.class);
[/code]
It says that thetokenisinvalid, and raises this exception:

Hi, I am glad to be useful for you. Moreover, in the near future I am looking forward to [Built-in support for OAuth OpenID]. thanks.

If you use not UserService but [com.google.gdata.client.http.AuthSubUtil] the problem might be solved. I think that this link is useful.http://code.google.com/intl/us/apis/gdata/docs/auth/authsub.html Please try. thanks. Hi GAEJ Experts, I like to access (Read/Write) a GoogleCalendarfrom the Google App Engine. To learn how it works I have Up my Java Google App Application and on my PC a smallCalendartest program. Now I need the missing link how to combine both application's. In my GAEJ servlet I get the current user with : UserService userService = UserServiceFactory.getUserService(); User user = userService.getCurrentUser(); (after successfully login ) And have access to the user Nickname, email address ... To access thecalendarI need the user and password. CalendarService myService = new CalendarService( exampleCo- exampleApp-1); myService.setUserCredentials( myAccount, myPassword ); I understand that I have no access to the User Password. For this reason I think there must be a other way around to access the usercalendar's. I can't believe there is no other way to access the CalendarService ? Any Idea ? Magic Cookies ?

[appengine-java] createLoginURL - userservice takes me to custom google apps domain login page
My code on the server is
if(userPrincipal != null){
String name = userPrincipal.getName();
site.setNickName(name);
site.setLoginLogOutURL(userService.createLogoutURL(thisURL));
site.setLoggedIn(true);
}else{
site.setNickName(Guest);
site.setLoginLogOutURL(userService.createLoginURL(thisURL));
site.setLoggedIn(false);
}
The Problem is that the URL takes me to the custom Google Apps Login
page instead of the standard google accounts login page.
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??
