 It seems as though a new application would need to be created for this to

 which makes it a little difficult to test or play with.
 What is the ETA/schedule on the feature complete 1.3.4 release?
 Thanks.

Hello -

I want to use http://fakedomain.com instead of http://fakeapp.appspot.com.
I went through the domain setup in the app engine dashboard and added
www.fakedomain.com. I also added the www CNAME record to point to
ghs.google.com in my registrars (GoDaddy) administrator panel. Now I
can access my app through www.fakedomain.com. I tried to do the same
for *.fakedomain.com but apparently GoDaddy doesn't allow wildcards
for CNAME records? Anyways, not really Google's problem, I just have
http://fakedomain.com forwarded to http://www.fakedomain.com.

First question: Is that how I am supposed to set it up?

Second question: My app should GET and POST to www.fakedomain.com,
correct? Is there a lot of latency introduced because of this?

I'm not sure if this is a good test, but a ping www.fakedomain.com
takes 150ms and a ping to fakedomain.appspot.com takes 10ms.

 Hey,
 
 Saving binary data to the datastore isn't too difficult - you can
 just
 use a Blob type and ensure that you don't break the 1MB capacity of
 a
 single entity.  You can see my class declaration below.  The hard
 part is converting a file upload to a byte[] and then from a byte[]
 back into what you would consider a downloadable file.  That
 depends, somewhat, on your implementation.  For example, I use the
 Wicket architecture and all I need to do is
 
 FileUpload f = fileUploadField.getFileUpload();
 BinaryFileData b = new BinaryFileData(f.getBytes());
 pm.makePersistent(b);
 
 I presume you are not using Wicket, but some other framework.
  You'll
 need to look into how it handles file uploads.
 
 You may also find this interesting:
 http://code.google.com/p/gaevfs/
 I haven't used it, but it skips the whole byte[] thing entirely.

No, the same problem is also in spring2.5

there is no better way to avoid that, you can try to run cron job to make

I am using Spring MVC version 3.0.0 RC1. I can't really do much to
reduce the loading request or application/framework initialization

other than switching to other framework or plain servlet. However, I
also see a lot of posts by other on loading request issue even in
plain servlet.

What about my customer use another google id to login in another page

In the past, I always use Session to storage user information to id

i could not get it up and running one month ago with a large datset. i
know the compass people are working hard to resolve issues with the
gae, but i doubt (technically) that lucene is able to run properly on
the app engine datastore (please correct me).

it might, however, run well with a smaller dataset (100megs, offline
indexing, and/or using an index file in the war folder)...

I think deploying a compass app on gae is not possible because the

Re: [appengine-java] Workaround for like keyword in JDOQL

2010-02-11 Thread yjun hu

you can try compass to search

On Fri, Feb 12, 2010 at 7:03 AM, John Patterson jdpatter...@gmail.comwrote:

The usual approach to complex queries in GAE is to process your data before
you need to query it. So in this case for each person create an index
entity which simply contains a list of partial names e.g. Pliyush,
iyush, yush, ush

Then do a keys-only range query for the name part e.g. iyu (look into how
to do range queries). Then take the result key's parent and look up the
Person entity.

On 11 Feb 2010, at 18:26, Piyush wrote:

Hi All,

I am developing a resource allocation application in GAE with Java.

Since there is no like keyword in JDOQL, I am unable to do search in
database based on a keyword. For example, I want to list all the
employees who have 'ash' word in their name.

I have already wasted 3 days due to this problem. So please suggest me
some workaround to achieve above this goal.

Thanks in advance.

 在中国appspot的https无法正常工作，因为gfw屏蔽了这部分，你寻找一个https代理，然后再测试应该就没有问题了！

I created a sample cron job with an excution frequency of 2 minutes
just to experiment with the working of cron on GAE. After a few
invocations, I decided to remove the job. I deleted cron.xml and
deployed my app on GAE. However, the cron continues to execute. How do
I remove the job?

Re: [appengine-java] Re: Spring TimerFactoryBean and ScheduledTimerTask not working on AppEngine??

2009-12-30 Thread yjun hu

I try schedule with spring on GAE, and it does not work too.

GAE has some function like cron jobs with 'cron.xml', you can try it

 Indeed, the TimerTask class implements Runnable...damn.
 Didn't know that threads aren't allowed.

 Thx

  Are those Spring classes creating threads? This is not allowed on GAE.

   Hi,
 
   I configured a TimerFactoryBean through my Spring configuration file
   which launched a ScheduledTimerTask in given time intervals for
   performing some work. Locally when developing within the hosted mode
   browser in Eclipse it works just fine, but when I deploy it to
   AppEngine I get the following error in the logs:
 
   Here's the stacktrace:
 
   org.springframework.web.context.ContextLoader
   initWebApplicationContext: Context initialization failed
   org.springframework.beans.factory.BeanCreationException: Error
