[appengine-java] Are incoming http requests executed in parallel or concurrently?

2012-02-15 Thread Marc Hede 
Hello all,

Coming from python, specifying "threadsafe: true" creates CPU-bound 
incoming http request threads, which limit an instance to handling one http 
request thread using the CPU at any time.  On the other hand python does 
allow handling of parallel I/O within a given http request thread.  This I 
believe means python http requests threads are only concurrent and switch 
between threads during a blocking operation, not execution in parallel.

I would like to know if Java is the same as python, or if specifying 
true means each incoming http thread is executed 
in parallel.

Is the following assumption correct?
Assumption: That would mean Python incoming http requests are handled 
concurrently, and python async api's are handled in parallel, and that Java 
incoming http requests are handled in parallel, and Java async api's are 
handled in parallel.

Thanks in advance to anyone who can shed light on this.  Please let me know 
if my assumptions of GAE Java are correct.

Best

ConnectionPool : do any of C3P0, DBCP, or BoneCP work with CloudSQL ?
If so then you can use DataNucleus support for those (look at the DN
docs).

Does the GAE File API support GAE projects created with a Google Apps account?

http://code.google.com/appengine/docs/java/googlestorage/overview.html
 says:
   Copy the value under Service Account Name. This is the service
account name of your application, in the format
application...@appspot.gserviceaccount.com. If you are using an App
Engine Premier Account, the service account name for your application
is in the format
application-id.example@appspot.gserviceaccount.com.

When I visit this page:
https://code.google.com/apis/console/b/0/#project:476894375364

and try to add this user (the account I'm trying to access the file api from):
   apptes...@appspot.gserviceaccount.com

I get the error:
   User apptes...@appspot.gserviceaccount.com may not be added to
project "API Project". Only members from domain systemsplanet.com (my
Google Apps Domain) may be added.

Sincerely,  Mike Lawrence

[appengine-java] Re: Handling ISO-8559-1 encoded parameter values in request

2012-02-15 Thread Ronoaldo José de Lana Pereira 
Hello,

You may find something usefull here: 
http://stackoverflow.com/questions/3278900/httpservletrequest-setcharacterencoding-seems-to-do-nothing.
 
I suggest you to try setting the encoding of the request prior to 
processing any information, it may works for the query string too.

If that wont works, It seem's that this is configured in the servlet 
container. Maybe you can try reading the whole QueryString 
(req.getQueryString()) and see if you can convert it using one of those 
methods: 
http://stackoverflow.com/questions/655891/converting-utf-8-to-iso-8859-1-in-java-how-to-keep-it-as-single-byte
 
(just change the from/to encodings to match your case ISO -> UTF8).

Please post here if it works.

Hope this helps,

-Ronoaldo
