I like Jeff's solution as it's failsafe, but one more pattern I often
use is to set a couple of flags, and
complete the 2nd action in a finally clause if needed. The timeout
for the 30 sec limit does allow for a very quick
transaction to still succeed, so I use that time to persist any state

sorry you're having problems.
dont think this is an app engine issue
since many folks use stripes on gae.
here are the stripe parts from my web XML
?xml version=1.0 encoding=utf-8?
web-app xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xmlns=http://java.sun.com/xml/ns/javaee;
there is no file system in gae so
the multipart wrapper could be your problem.
it probably would work locally by not in prod

I think you need to use a uppercase B for the classes.
When I tried deploying using a lowercase b1 eclipse was complating about a
volidation with the backends.xsd.
Try this:

Just a little question. I am using this pdfJet thing.
The requirement for us is to create a pdf and then mail it to a user.
So i am done with pdf creation part and at then end i have the code like:

PDF pdf = new PDF(out);
some actual writing.

scenario where multiple applications are hosted in a single google appengine

applications are handled by a master application. master application will

You're writing the PDF as your web page output. Use a ByteArrayOutputStream

You should be able to use the RequestDispatcher object to do what you want
but you'll have to have mappings in web.xml for each of the servlets your
forwarding to for instance MyGalleryApp would have mappings that all start
with /MyGalleryApp/ (or something similar) so GalleryServlet would map to
Hi Vik,
Call toByteArray() method on ByteArrayOutputStream when finished with
creating PDF and then
MimeBodyPart attachment = new MimeBodyPart();
attachment.setFileName(whatever.pdf);
attachment.setContent(attachmentData, application/pdf);
Thanks 2 futher things
1. What is the link between toByteArray() and attachment part of the code? I
mean i do not see the byteArray being used anywhere in the code you
provided.
2. Servlet response is giving ServletResponseOutputStream and on googling i

Dennis,
You're half-way there :)
GAE won't create a backend for you until you use the appcfg.sh
'update' command to update the backends.
Check out the docs here:
http://code.google.com/appengine/docs/java/backends/overview.html#Commands
I also was really expecting the backends.xml file
thanks Ravi and Stephen for your responses. my application needs to do
mapping at run time, i.e. it wouldn't be knowing how may subdomains it would
be handling, so, i can't not use your techniques :(

The code snippet is from the link I provided. Replace the attachmentData in

Hello
I did implement an empty mulitpart wrapper as I listed in my previous
message so that was not the problem. Fortunately, I did solve my problem.
The problem was not in the Stripes configuration at all. I had a following
tag in my web.xml:
jsp-config

I'm planning to build a web service on GAE that I anticipate having to deal
with significant amounts of load. I therefore want to make full use of
memcache such that hopefully, most requests won't need to go to the
datastore.
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

Can you give me the exact command you used?
I'm not sure how to use appcfg.sh for the backend features. I'm actually

So what are the dir and [update] values supposed to be to make these

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.

Rewrote the code:

Works fine now. Method needed to be set or it defaulted to POST and
created problems.

Hi Matthew,
In your logging.properties file, can you set the logging level to ALL

cases, it's helpful to see exactly what's going on under the hood,
before the stack trace is generated.
If it's not clear to you what's going on
