I was seeing this test http://gaejava.appspot.com/
and i have seen that crud operations in python are faster than in jdo
and that in low-level api is faster than in jdo.
So, i am tempted to leave java implementation for my google app engine
apps and to use python.
Or is there a way to create apps
Hi,
You should give a try to packages like Objectify (recommended by
Google also: they tend to push people away from JDO / JPA...)
It is simpler to learn than JDO and much more efficient in terms or
performance.
I abandonned JDO for Objectify many months ago and I am extremely
happy about that d

I've seen a bunch of threads on this issue, but there doesn't seem to
be a definitive example of getting this to work.
Essentially I want to migrate my existing Python app to Java, and I
know I can deploy both versions into production. But I want to do lots
of testing locally before ever deploying
Hello everybody!
I'm using Google AppEngine with their built in web server. My
development goes about in a simple way: I make changes to my .java
sources or .jsp and compile using ant and to see the changes I have to
restart the development server.
I'm wondering if there's a way I can avoid this
Hi,
I am trying to use activemq inside a GWT project. I followed the
steps given in http://code.google.com/p/gwt-activemq/.
But when I tried to run the GWT project it gave me the following

Hi,
I swiched to a Mac, installed Eclipse with the googleplugin.
If I test my app on the Mac it terminates after a few seconds whithout
a message.
I generated a new webapp for gae, it´s the same with it.
I use:
Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 2

Me too (on a Mac after the update to JSE 6b24). Funny, it doesn't
happen all the time. I have more luck when I run the server under the
debugger. After that it will sometimes start to work without
debugging.
I notice this in the console, but I can't remember if it was there

I ran into the same problem earlier today, and had to search for quite a
long time to understand where the problem came from.
The problem comes only from GWT and is not related to AppEngine (obviously,
this topic shouldn't be in the GAE/J GoogleGroup, but anyway ... ^^).
GWT emulates the JRE on

For the last couple of days our app performance has tanked, with requests
that used to take a second or so taking up to 30 seconds. Since we've made
"minor changes" that "probably aren't the cause" something gave me the idea
of deploying the same code under a separate name, and comparing the two
Might the difference between your foo and bar deployments be the size of the
data set you have for each app? If the fresh install is consistently fine
and the old one is consistently slow, maybe you've hit a threshold where
some inefficiency in your queries or data handling has started to actua
The app doesn't use persistence at all: all the data it uses is read from
resource files ... and I believe these to be
identical in both cases. ( The app did use persistence and the cache API up
to about 6 weeks ago, but no longer. )
A couple of pages use an HTTP callout to an RSS feed, but the
Actually, I overstated things. The app actually now uses persistence VERY
LITTLE, and only on one page. But the persistent store on the second
deployment is empty. It would be strange if this was the problem, but it
could be.
Thanks again!

I have the same issue as you do. I decided to go with JRebel and it
works great with App Engine. I've been using it for months and it's
saved me a ton of time. IMHO worth the money.
