[appengine-java] Geospatial data management with GAE Java
I know that Geomodel is a solution for python users to manage geospatial information. What is available for GAE Java users in term of Geospatial data management ? What is the best solution ? Is there a native approach provided by GAE Java ? In case no solution is available, what are the workarrounds ? Is Google Maps Data Api the solution ?

Re: [appengine-java] Too many open files
Do you have a link to a bug / issue in a tracker or a page that describes this fault (and which versions of Jasper it might be in)? Here it is: http://code.google.com/p/googleappengine/issues/detail?id=2980 Which version of Jasper? I am using App Engine SDK 1.3.1 But does anybody actually deals with these bugs? I have reported the intermittent time zone issue (bug 2330) months ago, and it is still 'New'. Simple redeployment of the webapp resolved the problem, but today it has appeared again. My guess is that about a week ago some new version of the App Engine was deployed, and it uses a faulty Jasper. I wonder if it can be fixed? This server error on the most popular page doesn't do anything good for my webapp. Thanks, Alex On Tue, Mar 16, 2010 at 7:54 AM, Henning henning2...@hotmail.de wrote: Hello, my apps should have had a quota reset 1 hour ago.

[appengine-java] Re: Best practices for datastore and JDO?
Thanks a lot for your answer. It is very helpful. We also came to the conclusion, that we would have to fit the entity types to our query needs. We were thinking about maintaining specific query views while inserting data. We just needed to here from someone else, that this was a feasible solution. Cheers, Jacob Vennervald On Mar 6, 3:49 pm, objectuser kevin.k.le...@gmail.com wrote: I think the gap here is that a RDBMS (PostgreSQL) and the App Engine Datastore are totally different. In fact, I think the latter influences your design much more than the former. The sorts of joins you used to be able to do in your DB to efficiently retrieve data don't work in the GAE datastore. You need to build your data model around the queries you want to run efficiently. To say again, your data needs to be modeled to support your most important queries. I go through some of the reasoning in the modeling section of my blog (I've been away from GAE for a while so some of this could have changed): http://objectuser.wordpress.com/google-app-engine/ However, if you've not done so, I highly recommend reading the Google documentation: http://code.google.com/appengine/docs/java/datastore/ On Mar 5, 6:54 am,vennervaldjacob.vennerv...@gmail.com wrote: Hi Guys We have a small application running on JBoss, Seam, Hibernate and PostgreSQL that we are thinking about moving to GAE/J.

As a proof of concept of the performance of the datastore, we did an implemented one of our heaviest reports by joining 6 entities together. And the performance proved to be really bad. Infact we received the deadline exception before we got to join all the entities. From the platform we are running on now, this could be done in less than a second.

[appengine-java] using JDO level 2 caching
I'm interested to hear from people who have enabled the datanucleus JDO level 2 caching for App Engine-- how has that worked out? This thread: http://groups.google.com/group/google-appengine-java/browse_thread/thread/13cb942ceb97dc/3ab7518edf6a8bc6 suggests that at least one person had the experience that it was quick locally but that there was a mysterious slow-down when the app was deployed. But, as far as I can tell, there are not a lot of people using L2 caching on App Engine (or at least, they are not discussing it here). I'm curious also as to why the Google docs themselves do not mention this feature (as far as I can tell)?- would any of the Google people monitoring this group have input on that? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Request multi-ID support for our app through http://code.google.com/support/bin/request.py?contact_type=AppEngineMultiInstanceExceptionRequest and add our app to all google domains who want to use us - but that model doesn't seem scalable one, not I'm sure if our customers will be fine with granting us even temporary administrative access in order to add the app to their account. 2.

[appengine-java] Re: it's terrible slow when loading resource files
hi, If the latency only get 75-85ms, it surely is fine I think. The performance I expected is that the latency should be always under 300ms. But it always exceed 1 second from my PC testing. So it should be common network delay from my PC to app engine server. I am not a America user, and my PC is on Taiwan. Just to confirm, does App engine server provide a mirror mechanism? I will install the Page Speed plugin to do more testing. Thanks! :^) Have a nice day!

I've confirmed that you're using our optimized serving infrastructure for static files. What kind of performance are you expecting to see? I would also try this tool: http://code.google.com/speed/page-speed/ It may have additional advice about optimizing your javascript.

What about doing something like 'time curlhttp:// yourapp.appspot.com/.../a-small-file'? Also, you mentioned resource files. Just to confirm, are you talking about serving static files, or are you serving these files (and doing the 304 handling) yourself with Java code? If you send me your app id privately I can double-check this for you. It looks like just normal. I found the page initialize spent time is quite different on different browsers. My testing behavior is always press F5 to reload the page. The spent time compare is as the following: Firefox 3.6 IE 8 Chrome 4.1 = Safari 4.04 Safari Chrome is very very very very very SLOW to initialize the page. The average spent time is about 10~14 seconds when page reload. Firefox just spent 3~4 seconds to finish initialize the page. Even IE8 (spent 5 ~ 6 seconds) is faster than Chrome and Safari, very strange... ( In my memory, IE should be the worst browser of them. ) For a normal web service, a page init time should not over 3 seconds I think. Any suggestions? Have you tried YSlow or something equivalent? That may be useful. BTW, If I set billing to add Bandwidth Out resource will improve the server response time? No. We don't do any throttling of bandwidth. The reason why I choose to deploy on Google App Engine is that I think the server response and performance should be extremely fast like other Google web services. But the result is quite different as I wonder. :((( On 3月16日, 上午1時54分, Don Schwarz schwa...@google.com wrote: It looks like your files are taking about 400ms each, which may not be that bad depending on where you are located relative to App Engine's datacenters. What's an average ping time to your application's appspot.com page? I believe that the beige bars in the graph are time spent waiting due to your browser's per-host connection limit. You should try something like YSlow (http://developer.yahoo.com/yslow/) for advice on how to concatenate CSS and JS files, merge images, etc. On Mon, Mar 15, 2010 at 7:43 AM, firestoke firest...@gmail.com wrote: hi, I write a HTML page that use many jQuery plugins and AJAX call.

Re: [appengine-java] Re: App instance recycling and response times - is there solution?
As a followup, today (3/17) from 1-3PM PST I received several
instances of Request
was aborted after waiting too long to attempt to service your request. This
is on my app w/ zero users, just 3 requests/minute of a blank page as a test
load.

I setup some pings of my add a few minutes ago, and I'm still seeing

My ping setup can't go lower than 60s intervals, so I have two running
concurrently. Here's a sample of 20 log entries over 10 minutes,
with . Three recyclings occur, and they happen less than 10s after a
previous request. Really Google, you're killing my JVM after TEN
SECONDS? And I get to pay you for the ton of CPU each startup uses?
Sounds like the more recycling, the more profitable the App Engine
becomes.
