[appengine-java] No Quota Reset today
Hello, my apps should have had a quota reset 1 hour ago. It says now: "Next reset in 23 hours". But no reset has taken place during the last hour at all. What's wrong?

[appengine-java] Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.
Hi, I've got a strange problem with (I believe) my servlet mapping. I'm trying to map all requests for "/mountain/*" to a JSP file called "mountain.jsp". It works fine when I run it on my localhost, but when I upload the project to AppEngine, I get errors like the following: /mountain/5429370/index.html/index.html/index.html/index.html/ index.html/index.html/index.html/index.html/...etc The "/index.html" is repeated over and over until Chrome gives me the following error: "Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects." Chrome suggests clearing the cookies for the site, but I there are no cookies to clear. Here is my web.xml: http://java.sun.com/dtd/web-app_2_3.dtd";> mountain mountain.jsp mountain /mountain/* PeakPeekSite.html Has anyone seen this problem or understand what is going on?

[appengine-java] Too many open files
I believe this is something that needs attention of the App Engine Team. My webapp was working fine for months, but a few days ago one of the pages started to report server error with logs like this one: Uncaught exception from servlet java.io.FileNotFoundException: /base/data/home/apps/myapp/1.340488091741834760/inc/somefile.txt (Too many open files) This page is different from the others only in the way of using a few jsp:include tags, and it is quite popular too. I've read around and found a reasonable suggestion that a problem like this can happen because of a faulty Jasper implementation - the tag handler doesn't close the file properly. 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 wrote: > Hello, > > my apps should have had a quota reset 1 hour ago.

[appengine-java] Re: Best way to perform search on DataStore - Design Question
I am using compass as well and it works fine. The indexing part is costly and you might need to do task queue if you reindex large amount of data. Starting the search manager is slow and it happens a lot due to the suspend policy. You can also take a look at this project: http://code.google.com/p/gaelucene/ I hope there will be a native solution by GAE one day (is there an issue to vote for?)

[appengine-java] Please fix the buggy Jasper
Dear App Engine team, Could you please fix the buggy Jasper that keeps causing the 'Too many open files' problem when jsp:include is used on the page. This problem didn't happen for months before, but it happened a few days ago, now it reappeared after just one hour. Please fix it.

Re: [appengine-java] Blobstore upload callback without a redirect?
Hi, Don't know if it helps but we have a servlet that processes the fileupload and then redirects to another servlet with /some/code And that servlet is the one responding to the form just by writing a JSON string on the writer. In the FormCompleteHandler you can parse the JSON or check for errors. 2010/3/15 fletcher > Hello - > > I'm trying to create a file upload form that writes to Blobstore. > Let's say my form has two inputs, one of type file, and another, of > type text.

hi, The average ping time is as the following: Reply from 72.14.203.141: bytes=32 time=96ms TTL=51 Reply from 72.14.203.141: bytes=32 time=95ms TTL=51 Reply from 72.14.203.141: bytes=32 time=94ms TTL=51 Reply from 72.14.203.141: bytes=32 time=95ms TTL=51 Reply from 72.14.203.141: bytes=32 time=99ms TTL=51 Reply from 72.14.203.141: bytes=32 time=98ms TTL=51 Reply from 72.14.203.141: bytes=32 time=97ms TTL=51 Reply from 72.14.203.141: bytes=32 time=95ms TTL=51 Reply from 72.14.203.141: bytes=32 time=97ms TTL=51 Reply from 72.14.203.141: bytes=32 time=98ms TTL=51 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? BTW, If I set billing to add "Bandwidth Out" resource will improve the server response time? 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 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.

thank you Chau for your fast reply, but I already looked in there, and the mentioned version (1.2.28) doesn't exist in the struts official web page or any known public maven2 repository, that is why I raised my question here. Any help would be appreciated. I also thought that maybe the version was wrong, and maybe it just needs a correction on the version number. thanks in advance!

I guess that is possible, but seems like a poor design decision. It makes adding custom indexes after-the-fact really, really painful. Can someone official chime in on this? Is it intended behavior, or should we file an issue against it? The documentation doesn't say much on the subject, and all the conceptual explanation of queries suggests that these extra single-property indexes will be unused.

[appengine-java] JDO - PM object 'involvement' in transaction
I am seeing some transaction-related behavior, using JDO and GAE
1.3.1, that puzzles me.
I get an exception if I do something like the following. All entities
below are in (their own) separate entity groups:
PersistenceManager pm = PMF.get().getPersistenceManager();
//... fetch entity a1 of kind A, modify a1...
// create or update several instances of kind 'B' in sep.
transactions
// (none share an entity group)
for (String i: coll) {
Transaction tx = pm.currentTransaction();
tx.begin();
//... create or update instance i of kind B, make persistent
tx.commit();
}
// ...
pm.close();
Each transaction only includes work on a single entity (of kind B).
However, the transactions throw the "can't operate on multiple entity
groups in a single transaction" exception with respect to kinds A and
B. Note that entity a1 was NOT actually part of any transactional
activity but *was* accessed first as part of the PersistenceManager
session.
When I use a second different PersistenceManager session for the
series of transactions (and make no other code mods), all is well.
e.g.:
PersistenceManager pm = PMF.get().getPersistenceManager();
//... fetch entity A1 of kind A, modify A1...
PersistenceManager pm2 = PMF.get().getPersistenceManager();
for (String i: coll) {
Transaction tx = pm2.currentTransaction();
tx.begin();
//... create or update instance i of kind B, make persistent
tx.commit();
}
pm2.close();
// ...
pm.close();
Here, each of the different instances of kind B are in their own
individual entity group, but the series of transactions can share a
PersistenceManager session without error.
But, sharing a PersistenceManager session with the entity of kind A
was problematic. Is it that one can't 'mix' transactions and non-
transactional operations in the same PersistenceManager session?

[appengine-java] DeadlineExceededException and Spring initialization
Hi, I'm having problems with my web application initialization process and the 30s per request limit. So I wonder what does everybody else do in this situation, because I think it should be quite common to everyone using GAE with Spring. First of all, sometimes, the delay between the request being accepted by the server, and the application being called sums up to several seconds. For example, here is a log, in which the application is being started, and the GAE waits 16 seconds to start my application from the moment the request has been received 03-12 07:47PM 22.698 / 500 30232ms 23651cpu_ms 65api_cpu_ms 0kb Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1),gzip(gfe),gzip(gfe) 58.61.164.40 - - [12/Mar/2010:19:47:52 -0800] "GET / HTTP/1.1" 500 0 - "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1),gzip(gfe),gzip(gfe)" "" I 03-12 07:47PM 38.041 javax.servlet.ServletContext log: Initializing Spring root WebApplicationContext So, that leaves my application 15s to initialize and handle the request. Something easy in my local computer, but rather difficult in GAE, don't know why. Is there a way to improve this? Why does it happen? Why is so big the delay?? It bothers me, in other situations too; when I wan to improve my app total request/second capability. I have, on one side the 30 simultaneous request limit, and the time a request takes to complete. My second concern, is how to improve spring startup time. We tried setting default-lazy-init=true; also we have 2 servlets, and we set web.xml: to false. But we are still receiving the DeadlineExceededException sometimes. Any ideas or strategies to improve the startup time?? Finally, I was wondering if it is possible to handle within spring the DeadlineExceededException, and show a nicer error page. Is it enough to use the Spring HandlerExceptionResolver mechanism? Or maybe GAE won't give enough time to finish the exception processing? Any help or ideas will be greatly appreciated!!!

[appengine-java] Google Plugin for Eclipse 1.3 is now available
Hi everyone, I'm happy to announce the release of version 1.3 of the Google Plugin for Eclipse (http://code.google.com/eclipse). This release is designed to make life easier for developers using GWT and/or App Engine alongside third-party tools. For example, we've taken the pain out of using the plugin with projects built with the ever-popular Maven build system: no more ugly hacks or workarounds, or polluted WEB-INF/lib directories! We've even added a new FAQ dedicated to Maven usage: http://code.google.com/eclipse/docs/faq.html#gwt_with_maven. We've also worked hard to make sure the plugin works well with Dynamic Web projects in Eclipse for Java EE. See the following FAQ for details on this scenario: http://code.google.com/eclipse/docs/faq.html#gwt_in_eclipse_for_java_ee. In addition to improving third-party interoperability, we've also made the plugin more customizable and robust overall. Launch configurations now allow direct editing of generated command line arguments, and a new Errors/Warnings preference page lets you tweak the severity of any problem marker we create. We've also fixed a number of bugs related to App Engine ORM enhancement. To install the Google Plugin for Eclipse, you can find our update site URLs, along with detailed instructions, here: http://code.google.com/eclipse/docs/download.html If you're upgrading from a previous version of the plugin, you may want to consult our Upgrading the Plugin guide: http://code.google.com/eclipse/docs/updating_the_plugin.html *Note: If you installed the Google Plugin for Eclipse 1.3 Preview, be sure to remove the relevant subfolders from your /dropins folder before installing the official 1.3 release via the update site.* *Enhancements* - Configurable WAR directory to allow better integration with Eclipse for Java EE and projects built with Maven - Web Application launch configurations now display and allow editing of generated Program and VM arguments - Errors/Warnings preference page for customizing the severity of any generated problem marker - Projects can reference GWT/App Engine SDKs directly via JARs instead of through SDK library - GWT+App Engine projects automatically configured for optimal caching *Fixes* - GWT Issue 3583: Google Eclipse Plugin configuration is too strict - GWT Issue 3592: Eclipse plugin to add 'cache forever' configuration for new 'GWT + App Engine' projects - GWT Issue 3902: Allow users to configure the severity of problems reported by the eclipse plugin - App Engine Issue 1515: Eclipse plugin requires fixed location for war directory - App Engine Issue 2115: Using the @PersistenceAware annotation puts the Eclipse Enhancer in an Infinite Loop - App Engine Issue 1941: Plugin fails to enhance dependent classes on source level changes For a complete list of fixed issues, see the GWT issue tracker and App Engine issue tracker. We hope you enjoy using this new version of the Google Plugin for Eclipse for all your GWT/App Engine development needs! Let us know if you have questions or run into any issues. Thanks!
