[appengine-java] Re: Performance issue for GAE auto-restart
Hey, The logs show what is being GET for any message. When loading some pages, I noticed that, beyond the initial delay of the page, I saw an 8s delay on one of the javascript files that was referenced in the code. When I checked the GAE logs, I saw a startup request for the initial GET for the HTML and then one immediately following GET for the javascript file. I suppose it is possible that this was a new instance spawning (instead of a restart), but I find that unlikely since I was the only user of my application. Or, if it is the case that GAE needs to spawn multiple JVMs to support one full page request, I think that is a problem :) Anyways, end result is that from a period of inactivity with no instances running, I went to my homepage once and saw two loading requests in the logs right after one another for that single page load. This has happened more than once. Granted, it's now been a couple of weeks since I last tested this behavior, but I haven't heard any feedback on my issue to suggest that it has changed.

[appengine-java] Re: Performance issue for GAE auto-restart
Hey, Here's a concrete example. One page load, 3 loading requests: one for the library page, another for a CSS file for that page, and a third for an image on that page. The end result, after a lot of optimization, is 24 seconds from initial page arrival to full display. And, it's likely that by the time the page has displayed, the JVM instance has shut down and the next user interaction will cause another loading request. 05-27 08:59AM 16.068 /resources/indira/img/buttons/share_o.png 200 4665ms 4160cpu_ms 1kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 05-27 08:59AM 20.707 This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time.

[appengine-java] Re: Performance issue for GAE auto-restart
Hi Jack:
I suggest that maybe you can write a ServletContextListener to monitor
the web instance reloading issue, for our testing we just put a info
logging in the contextInitialized(..) method:
public void contextInitialized(ServletContextEvent evt) {
log.info(Web context inited.);
}
And modify the DEFAULT logging level to INFO in the logging.properties
file. If the web instance was reloaded, we could trace this in the
logging messages.

[appengine-java] Re: Performance issue for GAE auto-restart
Hi all,
@Thomas: I will look into that, thank you. The way we generate our
pages in this framework, however, involves some interesting dynamic
generation of image URLs that are mounted within the application
itself. It ends up being a bit more complicated than just displaying
one string or another for the src attribute. Whether this is a good
practice on GAE is certainly up for debate, but I presume this
wouldn't help the frequent restart issue, correct? It just means that
fewer files would be able to trigger a restart?
@Tin: I'm not sure I understand what I will learn from this. From
what I understand, contextDestroyed() is never called so all I would
see is an additional log statement near GAE's loading request logging
line? I've never used a ServletContextListener, so perhaps it has
other features that I'm not aware of?
Thanks!
Jake

[appengine-java] Sending XMPP message with HTML anchor tag
Hello. I can send XMPP messages to the Google Talk client using the API provided with GAE. However, I'd like to send a link that people can click on, as well as do some simple formatting. These links contain a lot of request parameters, so they are long and messy- looking. I'd prefer to hide that detail in an HTML anchor tag. How do I use the API to format a message to accomplish this? Does the API support generating messages with embedded XHTML as described in http://xmpp.org/extensions/xep-0071.html ? Does the Google Talk client recognize XHTML? When building the Message, I've tried various combinations of html and body tags in an attempt to make the resulting Message look something like Example 1 in the document above. If I don't build the Message with .asXml(true) , then all the html tag information gets printed in the Google Talk client as text. If I try to use .asXml(true), then that section of the message body is ignored in the Google Talk client. For example, I try generating message text as follows: StringBuilder buffer = new StringBuilder(); // Will hold message text buffer.append(html xmlns=\http://jabber.org/protocol/xhtml-im \); buffer.append(body xmlns=\http://www.w3.org/1999/xhtml\;); // ... some XHTML is generated here, including a/a tags ... buffer.append(/body); buffer.append(/html); The toString() result of this buffer is then fed in as messageText in : Message msg = new MessageBuilder() .withRecipientJids(jid) .withBody(messageText) // .asXml(true) .build(); (The code just follows the examples in the documentation. Note asXml(true) was commented out). The result in the Google Talk client doesn't recognize the XHTML, so it looks too messy. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Datastore design
I've the following scenario. a) Registered users can post recipes (we anticipate on 5000 different recipes) b) Each recipe is part of 1 or more categories (we anticipate 100 different categories) c) Registered users can vote for recipes d) Registered users must select the country they live in 1) The site will display a list of recipes ordered on popularity. Including paging, so users would be able to browse all recipes 2) The same as 1 but based on a chosen category 3) Popular recipes by users in a specific country What is the most popular recipe in a given country. Including paging, so users would be able to browse all recipes 4) Same a 3 but based on chosen category I wonder how I can design this scnario using the Google datastore. In a relational database I would use some group by functions. Cheers, Marcel -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I am not so much concerned about it returning me the non-existent kinds - the doc does mention this scenario after all. But I am concerned that it does not return me info about my current kinds. Is this a known issue or am I doing something wrong? --- Also, on the dev server neither __Stat_Kind__ nor __Stat_Total__ return any entities.

Annotation problems will definitely do that. Other times, I've found that I need to do a Project - Clean from the Eclipse menu.

[appengine-java] Re: SDK 1.3.4 Development Mode showing import error blob/user
Well, for those like me who hit this, just a few things I have learned: a) Writing an application with GWT and App Engine support is trickier than app engine by itself with some html front end (which I had working). You have to really keep track of the new folders created. b) I was hoping I could mix JPA objects between GWT and App Engine, and put my JPA enabled files into shared folder. This was a key problem took me a bit to understand, refering to the gwt xml file which looks there for dependencies by default. c) When one does this, and does understand that GWT expects things in shared to be consumed by GWT, more care is required. GWT could not resolve the libraries as it appears to use a different build library path than the app engine server code. d) I have (for now) recreated my GWT and App Engine project, and put my JPA related files in the server path (I know, Duh, well, ah well, I was in a hurry, you know the speel...) e) Whew, i'm working again, but with brain dead GWT UI... work on that tomorrow morning. The project now runs the the default GWT support, and my JPA objects are ready to be used in the project. I have to read a few more articles on how to transfer objects between the app engine proper and GWT (so far is seems complicated), and I was hoping to use my JPAs as POJOs even in GWT, but well, that I'm not clear on yet. This should help a searcher who hit my problem, and save several hours scratching their head, looking at web pages, and messing with the eclipse build path settings.

Also, I created an EMF like static class, and also the javax.persistence.EntityManagerFactory, and they also can't be found now (this application actually worked a while ago). I have checked the project build path, and libraries in the GWT SDK (using GWT), App Engine and JRE 6 jar are included. I tried to explicitly include the jpa and geronimo jars where these exist, but no luck with that approach. Anybody hit something like this?

[appengine-java] indexes and Eclipse plugin
I'm getting some very confusing behavior regarding indexes in my app. Maybe someone can help me figure out what's going on. I have a persistent entity, GameDataV1. I'd pushed several versions of my app to appspot with no issues until last week. Then, after a push, all indexes for GameDataV1 were gone. I could still query it based on the index in a dependent object, but all queries on fields in GameDataV1 failed. I tried pushing a new version to no avail. This evening I tried inspecting the datastore-indexes-auto.xml file running locally out of eclipse. I deleted the DB and indexes to start with a clean slate. In general, the first time I execute a query requiring an index, I see that index show up in the XML file. But periodically I'll run a query and the file will collapse to an empty datastore-indexes element. Queries continue to execute without error, but return 0 entries. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
