Hi..
The Bulkloader works really smooth for me... but I have some important
questions.
I have downloaded data from a GAE/Python App which I wish to use in a
GAE/Java App.
I am having trouble with converting Entities with String Keys (python)
to Entities with Long as Keys (java).
My Questions:
Yesterday I had the bad luck my internet connection was not working.
While starting up App Engine dev server ik took more than 1 minut to
startup and it gave me the following exception:

Hi Keremonal,
As my practice I don't depend on Cookies for session management, because if
cookie is disabled at client browser then you will always get a new session
id and your data which was previously stored in session gets lost. As I

Cookies are the most suitable thing for the remember me functionality best

Is it possible to define system properties in the admin console?

Well, for me it's kinda strange, because i think i don't really
understand what's going on...
Let's say I want to get all my documents using gdata for docs list

a query to datastore to get parameters: 31 ms) then an url_fetch
You can use the datastore to put and get config values and use the
admin console to change them live.

Hello!
I want to use BlobstoreService to upload and store some files.
I have uploaded my simple app (made from GAE sample) and got
NoClassDefFoundError.
It's ok.
But even after I have enabled the billing, I keep recieving this
error.
I even try to redeploy my app with minor changes.
No luck.
Logging works fine in the production environment. I put my
logging.properties file in the right place and told GAE where to find
it and all is fine.
Now, when I try to use the same logging.properties file during my
JUnit tests it is completely ignored. I'm not sure how to tell ant to
use it.
You can also put them in appengine-web.xml and add a note to install.txt

Keep in mind that sessions managed by the servlet container expire after a
specific time of inactivity on the server side, so if a user comes back
after a while with his old session cookie, he will still get a new session.
According to the servlet spec, you can obtain this value with

This is the nature of memcache; you're sharing it with all the other
users of appengine. Memory pressure will eventually push your
inactive values out of the cache.
