dont think this is an app engine issue
since many folks use stripes on gae.
here are the stripe parts from my web XML

there is no file system in gae so
the multipart wrapper could be your problem.
it probably would work locally by not in prod

GAE won't create a backend for you until you use the appcfg.sh

I'm planning to build a web service on GAE that I anticipate having to deal

There will be several different users of this web service, and each
memcache is shared between all instances, so there's no need to check this
you should also have a look at datastore namespaces

HI,
From the description of your needs, it seems that the Java inheritance
mechanism is all what you need.
Yours servlets should all inherit from HomeServlet, in their doGet()
method, they will just call super.doGet() at the beginning and then
execute their own thing.

According to Ikai and other Googlers a very real cost to GAE is the
memory consumption of apps that don't use a lot of CPU but still have

So why not add a charge for memory usage x time? If one instance used

I very much agree with this suggestion. I've put the heavy lifting on
backends, and frontends merely serve simple requests now with only
about 10MB memory usage, but would still be charged the same amount as
