Note, I am also MacOSX snow leopard. I have been hacking away in App Engine and Vaadin before 1.3.2 and it has been working flawlessly. I tried moving the project to a newly downloaded copy of Eclipse (the JavaEE development version) and then installing Google Plugin. The same issue as described a

In Eclipse, go to Project / Properties menu. Go to Google / App Engine / ORM setting. It probably is set to src/ (using this setting DataNucleus puts all class files on its classpath). Instead restrict the folders (or patterns) to just the folders or file name patterns for your files that need enha

Re: [appengine-java] Slow app JVM wake - even with no data store access?

I guess it is what it is. I don't consider myself lucky though, because I spent three weeks migrating from JDO :). Yeah, Spring is great and all, and would work just fine on a huge site on App Engine, but the documentation should be clear about how much time should be expected for each of the commo

Re: [appengine-java] Slow app JVM wake - even with no data store access?

3-4s is pretty close to "as good as it gets" to start a JVM, load your app, and begin serving pages. I've seen 2s load times but 3-4s is pretty typical. Consider yourself lucky! The poor souls running Spring apps usually wait 15s+ for cold starts... Jeff On Mon, Apr 19, 2010 at 4:58 PM, Blake

[appengine-java] Slow app JVM wake - even with no data store access?

I switched from JDO to twig-persist to save load time, and it seemed to help a bit, but I'm still seeing 3-4 second load times on servlet calls that don't even touch the datastore. Wow. Of course, after the JVM loads, it's super-fast... but that first hit after a few minutes of inactivity - wow..

No. The GAE documentation is explicit: There is no guarantee that your data will exist in the memcache even 1s after putting it there. Will it be there? Most likely. But that's not very comforting given the time and energy required to develop an online game. When your system starts behaving b

What you are seeing is normal JEE behavior with cluster environments. The standard does not say that modifications to your session-stored beans should be propagated to other cluster nodes unless you explicitely invoke setAttribute(). You are experiencing the worst possible case (never increments)

Hi Vaclav: Thanks for your reply. HttpSession is a defined standard interface in JEE. The standard doesn't ask developers for explicitly calling HttpSession.setAttribute. The GAE/J provides a servlet container implementation which utilize datastore and memcache to store session data. It is

Sessions are stored in a Memcache and that's the reason of the behaviour you described. The Memcache low-level API documentation says: "The values returned from this API are mutable copies from the cache; altering them has no effect upon the cached value itself until assigned with one of the p
