[appengine-java] Need a better way to set up my JDO entities
Hello, I'm trying to retrieve race results from a couple of JDO entities but the time taken seems too long. Given an event I want to display the rider's name and number along with their results from the event. The main objects involved: RaceHistory: id, riderID, eventID, grade (for the race), time, place, points Rider: id, name, grade, number, rhPlace, rhTime, rhPlace, rhPoints I send an event id to a method that queries RaceHistory getting all the records matching the event id. Then for each RaceHistory record I lookup the Rider and set the Rider fields (rhGrade, rhTime, rhPlace, rhPoints) from the RaceHistory record. These Rider objects get added to the result ListRider object which gets returned. The time taken to do the RaceHistory query is about 1s. The time to find and update the Rider records is about 6s. The total number of records in the RaceHistory entity is 47387. The query returns 94 records The total number of records in the Rider entity is 1365. Can some recommend a better approach that I may take?

[appengine-java] Re: Blob Store service createUploadUrl() and a Dispatcher Servlet
Yes that is what the problem is. The getRequestURI() and or the getPathInfo() method are set to /ah/upload*. I am sorry for the confusion. On Apr 20, 12:33 pm, Don Schwarz schwa...@google.com wrote: I'm confused. What success path is being called? In the example web.xml file you attached to the bug, you don't have a servlet mapped to /uploadComplete so invoking of your DispatcherServlet after the upload occurs is exactly what I would expect. Is the problem that once inside your DispatcherServlet, getPathInfo() and/or getRequestURI() are set to /_ah/upload/* rather than /uploadComplete? If so, that sounds like a bug and I can investigate it.

However the right success path does not seem to get called. When i log into the admin console on DevAppServer, i can see the Datastore entities of kind __BlobStore__. The same code works correctly on the App Engine environment.

[appengine-java] Datastore cursor return value question - CursorHelper.getCursor(List?)
Hello app engine team, I'd like to have a search form, which allows user to search next if more result available by using a Cursor. My issue is, in the last chunk, I am not able to detect if it's. Therefore, I will need to execute one additional query to test if more data. Can you please advise if other approach, without using the 2nd query. Thanks. By document, CursorHelper.getCursor(List?) will return a Cursor which points to the last element in the list. The code is below (correct according to doc) import com.google.appengine.api.datastore.Cursor; EntityManager em = ... Query query = em.createQuery(queryString); query.setMaxResults(20); em.getTransaction().begin(); ListTestEntity testEntities = query.getResultList(); Cursor cursor = JPACursorHelper.getCursor(testEntities); em.getTransaction().rollback(); Then I will need to invoke one more call later, to check a null cursor returned indicates no more data available query.setMaxResults(1); query.setHint(JPACursorHelper.CURSOR_HINT, cursor); em.getTransaction().begin(); ListTestEntity testEntities = query.getResultList(); Cursor cursor = JPACursorHelper.getCursor(testEntities); em.getTransaction().rollback(); By curiosity (please correct me if I'm wrong), I looked into org.datanucleus.store.appengine.query and found that StreamingQueryResult returned by DatastoreQuery, which was in fact constructed from com.google.appengine.api.datastore.QueryResultList. The document say return a cursor that points to the result immediately after the last one in this list. http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/QueryResultList.html#getCursor() So I wonder if CursorHelper.getCursor(List?) can have something similar?

[appengine-java] Re: Need a better way to set up my JDO entities
I would denormalize your model and embed the rider in race history. That way there is no separate lookup and your query returns in 1s. You're doing the relational datastore technique of calculating on reads instead of the non-relational technique of preparing your data on the writes.

test2 is a simple servlet:
protected void doGet(HttpServletRequest request, HttpServletResponse
resp)
throws ServletException,IOException {
String itemName = request.getParameter(item_name);
System.out.println(itemName);
}
The paramter item_name is 中国(china).
In tomcat I can get the parameter by using the following code:
new String(request.getParameter(item_name).getBytes(ISO-8859-1),
GB2312);
But in GAE, I have tried many ways to get the right parameter value.
but all failed. Is there any configuration in GAE? If someone get it.
please let me know!
best regards.

Re: [appengine-java] Debugging stopped working after updating GAE to 3.1.0 and higher
Hey Ulrik, Ok, let's make sure a few other things are set properly: - Is the JRE used by the old web app's launch configuration the same as the new app's launch configuration? (Run Debug Configurations, click on the app on the left, then JRE tab) - Is your old web app redirecting in such a way that the ?gwt.codesvr= 127.0.0.1:9997 would get dropped? Basically, for debugging to work, that parameter must always exist as you traverse through your web app (so it must be preserved as you click on links, etc.) - Where is your breakpoint set? If it's in an anonymous inner class, there are generally issues with those getting dropped sometimes. Could you try one in onModuleLoad? - And just to make sure, the old web app is being launched via Debug As or the Debug Configurations (instead of Run As or Run Configurations)? jason On Mon, Apr 19, 2010 at 6:13 PM, Ulrik Sorber ulrik@gmail.com wrote: Jason: This is my URL: http://127.0.0.1:/MyPage.html?gwt.codesvr=127.0.0.1:9997http://127.0.0.1:/vehicles.html?gwt.codesvr=127.0.0.1:9997 http://127.0.0.1:/vehicles.html?gwt.codesvr=127.0.0.1:9997The page runs fine in debug mode, except it doesn't stop at any of my breakpoints.

(Apache HTTPClient, listed on http://groups.google.com/group/google-appengine-java/web/will-it-play-in-app-engine, is a different library). Maybe it is possible to replace the HttpClient class in the AWS SDK with a new implementation which uses the GAE URLFetch service? If somebody is faster, or code is somewhere on the web already, or if there are other problems which will make it too complicated, please share your knowledge ;-) Cheers, -- Michael Justin SCJP, SCJA betasoft - Software for Delphi™ and for the Java™ platform http://www.mikejustin.com - http://www.betabeans.de -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Amazon Web Services SDK on GAE/Java?
Take a look at this: http://alan.blog-city.com/simpledb_sqs_java.htm It is 2 classes to access Amazon's SImpleDB and SQS services. I have experimented with this on Android. I don't see a reason it should not work in GAE/J. If you want other Amazon services, these classes can serve as a good starting point.

[appengine-java] Re: Amazon Web Services SDK on GAE/Java?
Hi Carmen, thank you for your answer! This library needs to be rewritten too - it uses HTTP connection classes which are not supported in GAE/Java. So actually it is the same at the moment, if there are no other hidden surprises on the road.

No problem :) Hm, I think that if you had chosen to set the This project has a war directory setting, and set it to src/main/webapp, this error could have gone away. Yup, I discovered that eventually - it was all about the ordering. I think the best solution here would either give a more specific step-by- step process for GAE users (since the current correct path is to follow the instructions for non-Java EE Eclipse users) and/or have the error message that pops up give a hint about setting the WAR directory. I think for runtime, they are referring to the server on which your application will run. The best thing was indeed to select none, because App Engine's server is not one of the choices.

I know it's not Google's job to write FAQs for Eclipse, but you did such a great job with the other steps (in description) that it would be nice to have explanations here. As you say, the default worked, but you suggest adding other stuff like Web Services and JSF which, I'll admit, I know nothing about those words other than I see them a lot on these forums :) The GAE documentation frequently points people to other places where they can learn about non-GAE technologies - I hope that you do it here, too :) Looks like we need to have some sort of break-out in the FAQ for those users that are working with App Engine-only projects.

Couldn't you have gone back to Use Specific SDK, and chosen the one listed on your build path (instead of having to use one of the SDKs that are installed with the plugin)? I apologize...I have since had to wipe this test project (and the Eclipse installation) for completely unrelated reasons, so I can't reproduce anything at the moment - though I still have the pom.xml.

I'm not sure what the best solution is when mixing maven with the plugin (and I'm certainly not the best person to ask about it). However, it seems that if someone is dead set on using maven, then perhaps all jar files should be loaded via maven and the GPE could generate a pom.xml with the necessary base files. How did you end up fixing the problem? Was geronimo_jpa missing from the pom.xml? Yes, I put geronimo_jpa back in my pom.xml, which I think is strange since it was listed on the build path along with the other dozen+ GAE jars. This goes back to my previous comment. This is interesting (that it was working fine without GPE). It must be some sort of difference in your classpath in GPE vs. not in GPE. Can you tell me what: 1) Your build classpath looks like? 2) What files you have in your WEB-INF/lib folder? I did not put anything directly in my WEB-INF/lib folder - it was either dragged in by GPE or in my pom.xml. I've pasted snippets of my pom.xml below. I didn't do any modifications to my classpath other than to bring in the correct GAE SDK (which hadn't been done automatically via switching SDKs in the GPE menu). The refreshing of the target folder - was this something that you had to do manually? I guess you're saying that this is something we should doc after the mvn package step? Yup. Eclipse is really bad about refreshing folders in the Project Explorer. In my mind, I was going down the really bad path of believing that I would end up running this out of Eclipse's WTP folders (e.g. /Users/jacobbrookover/Documents/ workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/ wtpwebapps/app-id). That was a stupid mistake and ignored the instructions in the FAQ, but perhaps something as simple as On first run, choose the folder that looks like /target/app-id. It may not show up in Eclipse right away, so refresh your folders. In fact, you could even give a brief explanation of what the 'mvn package' step does. I know now how that plays out with GAE, but only because I learned it when trying to get maven to work with GAE before GPE 1.3. Feel free to peg me with any more questions. I may have time to re- create this all again tomorrow, if necessary. And, of course, any hints about the SAX Parser issue would

Re: [appengine-java] What is the best way to store child object?
Hi Andrey, I'll try to answer your questions inline. First off, I'm using these docs as reference: http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/KeyFactory.Builder.html http://code.google.com/appengine/docs/java/datastore/transactions.html It works. But there are couple things which bother me. First at all, there is some extra job here. I actually don't need instance of parent class (MyList). I have the parent key. Theoretically speaking, it is the only thing needed to maintain parent child relationship. MyList class may have more fields I don't need at all. So, I'd like to avoid reading them to memory. You can do this with KeyFactory.Builder. Build a Key using the parent and child Keys, then query using this Key. You can also use an ancestor query to find multiple child items. Second concern is about line myList.items.add(item); what if MyList already has million of items? How efficient is add operation in this case. It's O(Linear) in memory, but as far as saving goes, adding a new child element is a single row write + index writes. It's not dependent on the number of items you already have. We have a series of articles describing here: http://code.google.com/appengine/articles/datastore/overview.html Any thoughts? Is it possible to store child object using parent key only? Yep. Use KeyFactory.Builder to build and set a Key. Thank you, Andrey -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Using DataNucleus JPA - Online Quizzes Database Design
My second thought after posting previous message is to modify schema of ScoreBoar and make it a real scoreboard. Old: ScoreBoard(scoreboard_id as primary key, quizz_id as foreign key to Quizzes, 100, 90, 80, 70,60,50,40,30,20,10,0). New: ScoreBoard( identity id, quizz_id, foreign key to quizzes, user_id, foreign key to User user_score ) Table ScoreBoard has one-to-one to both table User and Quizzes. New schema would allow to post absolute value for each user and also it's easy to calculate percentage of other user's result below or above the current user's with sorting on user_score. right? On Wed, Apr 21, 2010 at 2:38 PM, bobo david.bo...@gmail.com wrote: Hi After leaning JPA tutorial with Getting Started tutorial, I would like to try creating my own web application called on-line quizzes with Google Engine. This application would provide users quizzes with uncertain number of questions for each quizz. And it displays the result a user plays, as well as tells the rank of the result among participants and percentage of performers below the result the user receives. If a user desires, the application would be able to tell the historic records of quizzes the user played in the past. I am stuck on how to design and flat tables for this application. Below is what I tried and feel the design is a bit of awkward and it may not fit into tasks the application would perfom: 1. User table(user_id, first_name, last_name) 2. Quizzes tables(quizz_id, quizz_name) User and Quizzes tables has many-to-many relationship. Each user has a number of quizzes and each quizz can have a number of users 3. Join or associate table User_Quizzes(user_id, quizz_id). Both ids are from User and Quizz table as a foregn key to its source table, and both as a composite primay key for this join table. 4. Record table(record_id, score, qizz_id, user_id). It has one-to- many relationship between User and Record table. Foreign key in Record table is a user_id. So we can retrieve historic records for a particular user; 5. ScoreBoard table, this is where I am confused and not confident. Each quizz will store distribution of users with different level of scores for a particular quizz, let's say 10 as an interval for score level and then it can tell percentage of users played above or below to this user. So it's one-to-one relationship between each quizz and its corresponding scoreboard. ScoreBoard(scoreboard_id as primary key, quizz_id as foreign key to Quizzes, 100, 90, 80, 70,60,50,40,30,20,10,0). If a user plays a quizz with 15 questions and have 11 correct, it's 73% correct for that quizz. I will update the column of 70 with whatever value there increased by 1. At this time, the total percent of peope below this user is: sum( values in column 60, 50, 40, ,0)/ total number of users participated in the quizz. With this database design above, firstly the application is not able to give the rank of absolute scores with the user's result(but can give a level rank). Should I create another table; Second, I am not sure if the design can eventually fit into DataNucleus JPA implementation. Do you have a better idea or experiences to make this type of database work?

I've got a problem with sending Multi-Part email using Spring's

It works fine without the multi-part (modified from the example in

final MimeMessageHelper message = new MimeMessageHelper(

final String htmlText = FreeMarkerTemplateUtils
.processTemplateIntoString(configuration
.getTemplate(htmlTemplate), model);
message.setText(htmlText, true);
}
};
mailSender.send(preparator);
But once I change it to:
final MimeMessagePreparator preparator = new MimeMessagePreparator() {
public void prepare(final MimeMessage mimeMessage) throws Exception {
final MimeMessageHelper message = new MimeMessageHelper(
mimeMessage, true);
...
message.setText(plainText, htmlText);
}
};

I get:

You can use a keys-only query to retrieve the keys of all entities that match a specific criteria, and use that, but if you do this, you should cache this count to avoid re-querying in every request. You may also consider estimating or otherwise giving a rough number if the exact count isn't important, similar to Gmail (e.g. 1-20 of hundreds). [9:17, 9:19-9:32] - Discussion on cold startup times for Python and Java applications -- all applications are cycled out after a certain period of time when no requests come in. Startup times are generally better for Python apps since the Python runtime doesn't have to load a JVM and most Python frameworks are smaller than comparable Java frameworks. For now, the only way to ensure that your application remains warm is to have steady traffic (generally more than one request per minute) from actual users, not cron pingers. Reserved instances are on the roadmap which will enable you to pay to keep your application loaded in the absence of traffic.

Welcome to the second IRC office hour session of the month. I and a few others will be in the channel for the next hour to answer any App Engine questions if you've got any, so fire away. [09:03am] perlmonkey2: hmm, the GAE webapp docs say that for template paths, the current dir is the application root directory. but passing in templates/mytemplate.html which is under the MyApp directory isn't working. Is this a bug or am I not Doing It Right? [09:04am] perlmonkey2: oh, office hours. I'll shut up for real questions [09:05am] rsaccon: @apijason_google is there anything you can tell us about forthcoming OpenId / oAuth service, beyond what is on the roadmap ? [09:05am] apijason_google: perlmonkey2: It works for me. This is the template path I set in my own apps: path = os.path.join(os.path.dirname(__file__), 'templates', 'index.html') where templates is the name of the directory at the root level. [09:06am] ikai_google: Hi everybody! [09:06am] apijason_google: rsaccon: What specifically would you like to know? The answer is probably not, although I can assure you that it's coming along. [09:06am] apijason_google: Hi Ikai! [09:08am] prencher: apijason_google: can you tell us anything about the upcoming reserved instances? guessing not, but if so I'd like to know whether we're talking about N hot spares at all times (including while there's load), or a minimum number of instances [09:09am] ikai_google: prencher: We can't give many details right now about any upcoming features. [09:09am] perlmonkey2: hmm, outputted the path. Looks like the docs might be wrong as the path is from the controller not the root path of the application. So if my controllers are in MyApp/lib/controllers, that is the relative path. Not Myapp/ as the docs say. Or am I doing it wrong [09:10am] perlmonkey2: Nevermind me, these are webapp questions. Hate to burn any time on this when there are serious GAE questions. [09:11am] apijason_google: prencher: The details are still being worked out, so nothing I say here is canon. But, to my knowledge, the team has been discussing the second option -- minimum number of instances. Everything is subject to change until release, however. [09:11am] yodler12: How's the pagination blog post coming? Any good pagination libraries yet that you know of based on cursors? Any advice if I'm going to try to write one? [09:11am] ikai_google: perlmonkey2: No, it's totally fair game, though you're generally better asking this in the groups [09:11am] apijason_google: perlmonkey2: Thanks for the pointer. Can you file a docs bug in the issue tracker?

Re: [appengine-java] using an Objectify query filter with IN -- IllegalArgumentException
Fixed. Although you might prefer to issue a batch get() operation instead of the query. There might be a performance difference - I'm not sure.

[appengine-java] Re: Datastore size growing one way
Thanks Ikai for a prompt response! Its been more than 24hours now and the datstore still shows up as 40% of 1GB usage. Generally, how long does it take to update? Also, in the past even when I delete significant amount of data from datastore, the datastore size never went down. However, the datastore statistics reflected the deletes. Is there anything else that occupies datastore size apart from datastore entities and indexes? If I delete all the indexes, will my datastore size match datastore statistics?

[appengine-java] Query returns more than limit
Hello, I have seen problem with Java, like this: - Fixed a datastore issue where an error was thrown when setting a query offset to more than the number of results throws an error. http://code.google.com/p/googleappengine/issues/detail?id=2875 I send this query: query.filter(:user_id=user.id).sort(:created_at, :desc).each(:limit=3) This query uses composite-index. UserNews user_id ▲ , created_at ▼ I set limit=3, but many (all?) entities are return. It is not always. very very rare case. This code is ruby, but I trace code, I found JavaAPI's PreparedQuery#asIterator(FetchOptions fetchOptions) is used. From application log. Maybe query is retried, by application code.
