*sessions-enabled *set as True. But with this setting, i am unable to
deploy to google app engine(in eclipse select project-->Right

Hi Adrian:
By plain normal servlet I meaned the url path (of the call to
blobstoreService.createUploadUrl(url) ) is mapping to a simple plain
HttpServlet implementation. And it is better to have the servlet
bypass any filter mapping in development phase. It's how I finally
succeeded to upload
Hi Thomas,
Thanks for your reply :) But I'm not sure what you mean by "a plain normal
HttpServlet#doPost to handle the upload"; in what sense am I not doing that?
Do you mean the fact that I'm uploading to Blobstore? Why would that be a
problem, and how else would I get them in there?
Thanks,
Adr
Hi:
I read the post on Stack Overflow. My opinion is that you had better
use a plain normal HttpServlet#doPost to handle the upload. I also
encountered 500 Internal Server Error, but it worked well after I
replace original handler with a plain servlet.
Hope the above helps!

Hello,
What is the best practice to generation sequence ids for persistence classes
like Country's id (for Country drop down)?
I mean:
1.Hungary
2.US
3.Spain
The well known Toplink annotation help suggest the following.
@SequenceGenerator(name="CUST_SEQ", allocationSize=25)
@GeneratedValue

It is most useful to specify EVENTUAL read consistency to increase
performance by decreasing error rates due to contention.

This is true only for the GWT client side (and not completely, since
Gin modules don't seem to be refreshed correctly).
For server side, JSPs look to be refreshed automatically, but you must
reload the server to have your RPC services updated.
If you use Eclipse there's a reload icon in the "Devel
