[appengine-java] In an application using the High Replication Datastore, the blobstore is eventually consistent too?
Hi everyone, In an application using the High Replication Datastore, the blobstore is eventually consistent too or it is strongly consistent? or simply: it is possible that in the servlet called after uploading a blob this line: Image im = ImagesServiceFactory.makeImageFromBlob(blobKey); could try to create an Image from a blob not yet available (like when you try to get an entity you just put into the datastore)?

[appengine-java] Re: Storing query results in memcache
Hi Ian, Thanks for sharing your strategy.. I am not sure if I understand exactly how could I use your system to solve my problem. Actually, the memcache concept is working nice solving similar, but simpler situations. I think I explained poorly my situation. Here it is: An application manages contacts. It actually has thousands of them. On the GUI side we have a listview, an editview and a createview. The list view has 4 columns, and is paged (30 records per page) and by default is sorted ascending by the first column. I can search the listview by issuing queries serverside (I want the results always ordered and paged accordingly). Now, a user clicks on new contact. The application goes into createView. Data input then save. Application goes to list view. The contact should have been in the first page, but it isn't. After a few seconds, it appears. The previous example with phone numbers is kind of the same issue, but with simpler queries: User modifies a contact by adding some phone numbers. Hits save and goes to list view, then he remembers that one number was wrong and goes back to editing the same contact. The phone numbers inserted seconds ago aren't there. In this case, (since for other reasons I the phone numbers entities cannot be children of the contact entity) every phone number entity has a property called contactId that points to the father contact. The solution employed in this simple case is storing in the memcache the phone numbers by using contact-based keys so that for example [code] memcache.get(MEMCACHE_phones_contactId_1234) [/code] would give me an all the phone numbers for contact having id=1234. Somehow (too long and boring to explain how) I manage to keep this array always up to date so when the user returns lightning-fast to the editview the newly inserted phone number are there, only that they are read from the memcache. Analogically, how could this be done for the fore-mentioned listview situation, where the query is much more complex? Hope I didn't confused you more..

[appengine-java] Storing query results in memcache
Hi, I just moved my app to HRD and I am trying to use the memcache to overcome the eventual consistency problem.. When it comes to get-by-id queries the solution is very simple. The problem appears when I insert an entity and I want to appear in the results of more complex queries. Because using entity groups is not the answer in certain situations I had to use some sort of foreign keys.. So far I thought of a system that gets an unique id from the query based on its FilterPredicates (eg: MEMCACHE_PHONE_NUMBERS_contactId_12345) and then uses that to update or read the entities from there. I would build this system by doing my own implementation of the DatastoreService interface and attach the memcache management on the various put/delete/get methods. I don't want to reinvent the wheel. Is there anything already done that I could use? If anybody has any suggestions feel free to enlighten me ;) Thanks, Cristian. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Payment Problem
Hi everyone, Since yesterday I saw that I owe to google 2.4$ and that the payment failed. When I go to Billing Settings I see this message: On this page you can set your weekly spend to any value at or below $0.00. If you want to raise the weekly spend above $0.00, you will have to adjust it once you have finished taking over as billing administrator. Also, there is another message: Since the last billing adminstrator had a payment fail, there isn't a billing administrator. What does it mean? It looks to me like a bug on appengine's side, because I double checked my credit card it is fully functional. I need to increase my daily budget because I want to move my application to the high replication datastore as the master/slave is slow and makes me losing 1-2 potential customers every day. Could someone please let me know something? appid: domodentweb Thank you very much and keep up the good work.

[appengine-java] Re: Recommended maximum number of entities in an entity group
Acually, I forgot about the fact that while a transaction is going on, all entities involved are locked. Therefore, I considered changing my database structure in order to get more, but smaller entity groups (every parentEntity will have at most 20-30 childs). That way, will be easier and faster to use transactions.

[appengine-java] Re: AuthSub InvalidToken problem
That's all the code that deals with google services in my whole
application. The exception is raised on the following instruction:
[code]
CalendarEventFeed resultFeed = calendarService.query(myQuery,
CalendarEventFeed.class);
[/code]
What about the environment? You are saying that I might have included
jars that could interfere with auth sub? Are there any known
conflictual libraries? I have simply included all the jars shipped
with the gdata-samples package.

Can post do you the source code further?

[appengine-java] memcache and session on GAE
Hi everyone. How memcache works on GAE? Let me explain: Do I get one memcache instance per app instance or there is one memcache instance for all instastances of my app? My app uses google accounts to handle users. I am thinking that it might be faster reading the current user data from the memcache instead of calling userService.getCurrentUser(). It would be a good approach? Thanks, Cristian. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: images over http
Sorry for the delay, but I canceled my subscription to this group on
nov 2 and therefore I saw your answer just now.
Anyway, the problem is still present. I haven't solved this issue, as
I preferred going on by implementing other functionalities and hoping
that in a successive GAE release it would be solved.
Here is an image URL that I am trying to fetch:
http://almaoffice0.appspot.com/GetImage?id=32001
Here is the source code of the servlet serving the image. Maybe the
error is there... You're the expert.
[code]
@Override
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException{
long imageId = 1;
OutputStream os = response.getOutputStream();
try{
try {
imageId =
Long.parseLong(request.getParameter(id));
} catch (Exception e){
return ;
}
FilesController c = new FilesController();
FileData imgData = c.selectById(imageId);
response.setContentType(imgData.contentType);
byte[] d = imgData.data.getBytes();
os.write(d);
} catch (Exception e){
e.printStackTrace(out);
} finally {
os.close();
}
}
[/code]
Thank you,
Cristian Babula.

Just to clarify:
Your URL Fetch request for a given image on your server fails after 6
seconds even though you've configured the deadline to be the maximum 10
seconds, and you've tried serving the image from another App Engine servlet
as well and saw the same issue. Is this right?
Can you send me the image URL that you are trying to fetch?

First of all, thanks for your answer.
I think further information is needed for you to understand my
problem. The server which encounters this problem, practically takes
as input some template pseudo-code, that contains references to images
(like html img src=img url/), and generates some output based on
that. In order to generate the output data, it has to download (via
java.net.HTTPConnection) the images from the various urls and
transform them. The problem is that already the first attempt to
download an image times out under 10 secs, although I did
setConnectTimeout(1).

Is the server on which your JPEG is hosted especially slow?
The server where the JPEGs are hosted is not slow. In fact, as I
mentioned above, I tried serving the images with an google app engine
servlet, but the error still remains. I supposed than, that the issue
is not on the server that serves the images.
Note that the
default timeout limit for URL Fetch requests is 5 seconds. You can
increase
this up to 10 by passing 1 (ms) into setConnectTimeout().
Already did that, but the browser's ends after 6 seconds.
Also keep in mind that your image will have to be smaller than 1 MB if
you're planning to use it with the Images service or store it in the
datastore.
As I already mentioned, that is not a problem, as I tried retrieving
the images from an application engine servlet.
Besides, I am very aware about the limits specified in the docs.

I have somewhere on the net a servlet that serves jpeg images. In

Now, I am trying to create an GAE image object from the data arriving

So far I tried this code*[1], with a lot of variations, and I keep

Problems: * Implement the required java.awt.* and javax.imageio.* classes. * Implement a complete Graphics2D in java. JVMs use the OS native drawing APIs. * Implement font management, atleast TrueType. Same problem here, JVMs use native. If there was aFOPengine using iText instead, it would be easier. iText uses alot less awt classes and got its own font manager. Good luck - please post if you getFOPworking.
