Re: [appengine-java] Reminder: Google App Engine community support is moving to Stack Overflow
Questions tagged with 'google-app-engine': http://stackoverflow.com/questions/tagged/google-app-engine I don't understand how to get java specific questions. It's not useful and a huge waste of time to have to sort through the python stuff for me. This sucks and it seems like google is losing it's mojo if it takes the natural categories and lumps them into one less useful one.

Re: [appengine-java] Reminder: Google App Engine community support is moving to Stack Overflow
Search for google-app-engine java. I still don't get it. searching pulls up results that are seemingly unordered by time using a Stack Overflow filter (to notify by email or display current results) doesn't find java related posts. YUCK. It'd be nice to be able to just follow the java version especially when a new release come out with it's inevitable problems. It helps me pin down what might be wrong. Also, do we need to have to follow two lists ... Maybe I'll get used to it.

Re: [appengine-java] Reminder: Google App Engine community support is moving to Stack Overflow
When you're searching, you can specify a tag by putting it in square brackets. E.g. if you search for: [google-app-engine] [java] spring this will retrieve questions tagged with [google-app-engine] and [java], and containing 'spring'. Thanks Amy, It's weird. Here's what worked. [google-app-engine] +java then sort by newest Here's what didn't work [google-app-engine] java because the site changed it to [google-app-engine] [java] BUT many posts are not tagged as java though they contained java in the post which is what I was looking for but not showing up Thanks for your help.

Re: [appengine-java] Implementation question regarding efficient check and lock on datastore
I guess what I want to have is some kind of check and lock. My question is how to implement an efficient lock on a distributed environment like GAE. Transactions? Or better using memcache?

Re: [appengine-java] Re: problem with Content-type: null with css files
We think we know what's happening. This is something that is happening at app upload time.

Re: [appengine-java] Re: problem with Content-type: null with css files
If someone has a deterministically reproducible case that you can share with
us (project files and everything), it'd be very helpful for us to nail this
bug. We aren't able to do this with our test apps (big apps, small apps).
There's got to be some parameter that's different in your apps.
I had the same problem and realized I can induce/eliminate the error
just by altering a comment (the first lines in the file -- not sure
about elsewhere).
test 1 - This fails:
/*test
*/
html,body,h1,h2,h3,h4,h5,h6,p,ol,ul,li,pre,code,address,variable,form,fieldset,blockquote
{
padding: 0;
margin: 0;
font-size: 100%;
font-weight: normal;
}
test 2 - This succeeds:
/*test
*/
html,body,h1,h2,h3,h4,h5,h6,p,ol,ul,li,pre,code,address,variable,form,fieldset,blockquote
{
padding: 0;
margin: 0;
font-size: 100%;
font-weight: normal;
}
test 3 - this fails:
/*test*/
html,body,h1,h2,h3,h4,h5,h6,p,ol,ul,li,pre,code,address,variable,form,fieldset,blockquote
{
padding: 0;
margin: 0;
font-size: 100%;
font-weight: normal;
}
test 4 - this succeeds:
/*test*/
html,body,h1,h2,h3,h4,h5,h6,p,ol,ul,li,pre,code,address,variable,form,fieldset,blockquote
{
padding: 0;

}
test 5 - this succeeds

{
padding: 0;
margin: 0;
font-size: 100%;
font-weight: normal;
}
(when combined with web.xml):
mime-mapping
extension.css/extension
mime-typetext/css/mime-type
/mime-mapping
NOTE: It's more complicated that I depict here as if I remove the
web.xml workaround for test 5 it still works. But then if I add
another space between the comment and first html rule, it fails again.
Anyway, just changing the spacing around the initial comment will
result in the mime type being set or not.
NOTE 2: I verified my css file was w3c valid but I have not posted the
whole thing. The only change was spacing around the initial
comment...
NOTE3: AE 1.6.1

[appengine-java] does the Google AppEngine or WebToolkit replace the bootclasspath of the running Java runtime?
Hi, I used the open-jdk workaround to solve the problems introduced by the latest apple java sdk update but have a question an Apple engineer asked me about the following: http://code.google.com/p/googleappengine/issues/detail?id=4712 http://code.google.com/p/google-web-toolkit/issues/detail?id=6125 does the Google AppEngine or WebToolkit replace the bootclasspath of the running Java runtime?

Re: [appengine-java] [Perhaps OT] Oracle vs. Google : Java still a viable language?
Motivation: I am at the early stages of implementing a web app on GAE using Java, but if I need to switch to Python, I shouldn't delay it any more. Anyway, what do you guys think? IANAL but you asked so here goes. I think you are fine using java on GAE. My guess is that since appengine is a derivative of OpenJDK that the (SE) patent grant holds for appengine as long as it doesn't implement new core functionality which the OpenJDK does not. In such a case, I don't believe the patent grant holds. You'd have to read the grant more closely or an analysis of it to know whether only partially implementing it carries the grant. Even if Oracle were to argue partial implementation does not, I believe the GPL2 combined with a patent grant for that code means effectively that Oracle can not say what people do with the GPL2 code, only that new functionality may not carry the protection. So, were GAE to fork OpenJDK and implement new core java classes (this does not mean new classes using java but a re-implementation of java with new functionality), then it's possible that we may see patent issues. Given the issues with Android though, I suspect Google will stay in the clear and I do not believe the GAE SDK does this. That said, if you try to take the SDK jars and set up an equivalent of GAE that runs on your phone (note: I am not talking about an app on a phone that connects to GAE, I am talking about *running* a GAE instance on a mobile phone) then perhaps you may have trouble as Oracle reserved the rights to mobile devices for non-GPL versions of Java. Nobody would or could ever do that I think, and so am sure it won't ever be an issue. Don't listen to me though. Really don't.

[appengine-java] Stored Data- how billed?

I really can't understand this. Help please It looks like this is related to the appengine developement server. When deployed, the filter sets cookies as expected. It's not that the cookie was at a different uri or something, there was just no cookie (JSESSION or anything I tried to set) being sent on the first access. I configured appengine-web.xml file to treat it as a non-static resource so yes the filter is called but under the dev server no cookie is sent for the first access.

Re: [appengine-java] Re: memcache best practice or framework
What's the usage for in-memory caching via stick-cache?

[appengine-java] Why are filters not used on first access?
Hi, I have a filter set for all requests. Yet the first request to GAE seems to bypass the filter. Why/How could that be? I do have a welcome file set welcome-fileMyAppGAE.html/welcome-file but shouldn't that get called by the following filter filter-mapping filter-nameAuthenticationFilter/filter-name url-pattern/*/url-pattern /filter-mapping Using a url like (running locally) http://127.0.0.1:/MyAppGAE.html?gwt.codesvr=127.0.0.1:9997#login, why does the filter get bypassed on first access. Subsequest rpc calls to the app do trigger the filter but I'm worried that before I can authenticate the user, they have a chance to make an rpc call. It's a huge potential security hole. If it's the browser caching something, then when I change the welcome page MyAppGAE.html, I would expect the filter to be applied when the user gets the new page. I can see the new page but still don't see the filter applied. What am I not understanding???

Actually Chrome reports: Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.

Re: [appengine-java] java.lang.RuntimeException: java.io.NotSerializableException: + objectify framework
I am using dwr and objectify framework to get the arraylist of string from datastore. But I am getting error. java.lang.RuntimeException: java.io.NotSerializableException Well beyond that have you really gotten dwr to work in appengine. If so, it must be a pretty old version. AFAIK, dwr uses threads and file writes. Have you modified dwr to avoid those? Shawn -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Why should app startup times be a problem.
It's boggled my mind from day 1 why instances aren't loaded in the background. I always assumed it would be addressed What is difficult to understand? 1 server has X resources warmed instanced require Y resources X - YN = resources left over for the server to fulfill requests. By reducing N (the number of warmed instances), you can increase the capacity to fulfill actual requests. By allowing us to pay for our own N, Google can presumably increase the capacity of each server or can increase the number of servers. I can see how it can cost Google to have unused apps loaded and ready to immediately serve. Can't you. I don't see what the difficulty understanding is.

Re: [appengine-java] GWT+JDO+GAE enhancement nightmare
This seems pretty basic. Can somebody wake me from this nightmare? Sorry, been there... If I was starting over, I'd seriously think about: http://code.google.com/p/objectify-appengine/ for two reasons: 1) Objectify entities can be used in GWT without the need for Data Transfer Objects. 2) it seems cold start up time is better when you take the jdo and datanucleus stuff out. (judging by mail on this list) There are much more knowledgeable people on this list but ... yeah I know it's a nightmare to get it figured out in the beginning and don't wonder if objectify isn't simpler.

Re: [appengine-java] GAE for few requests high processing
My Java App anticipates few requests, but a lot of processing. Hence it was designed to be multi-threaded. Since the multiple threads are not allowed in GAE max request processing time is only 30 secs with Task Queues, I'm looking at my options: 1. How do you develop high background processing application with GAE ?

Re: [appengine-java] Re: Why not use integer primary keys?
Well this won't help to use id as an array index but... * As you've probably figured out, the datastore natively only supports two types of id, Long and String * Only Long will autogenerate Key will autogenerate too won't it! and from the api: long com.google.appengine.api.datastore.Key.getId() getId public long getId() Returns the numeric identifier of this Key.

Yes its like a official release I can breathe again. Then move back original question. How should I teach Eclipse of this update? Can't you just update eclipse?

Re: [appengine-java] Re: DWR SUPPORT
Hi, Some said GAE did not support DWR while I had read about Will it play in App Engine.It showed that Direct Web Remoting (DWR) Version(s): 2.0.5, 3.0 RC1 Status: COMPATIBLE DWR uses threads for some things like reverse ajax. For sure, that will not work in appengine at least the way 3.0RC1 is written. It also writes files that don't work on appengine. Long polling isn't supported either. I've seen people on the DWR list try to work around that, but I've never seen a clean solution. Maybe there is one though. Here are relevant posts from the DWR list http://old.nabble.com/forum/Search.jtp?forum=13934local=yquery=dwr+appengine Anyway, your undifined error is most likely: 1) the path to the DWR script is wrong 2) the path is correct but when your javascript on the client loads, it send a call to the server to configure DWR. But by the time the call returns, your javascript on the client has already moved on and thrown the undefined error because DWR hadn't returned in time. I saw this with reverse ajax.
