You need to create a backends.xml file in your */war/WEB-INF/* folder and
set up a backend. For example, the following XML sets up a backend named
*worker*:
<backends>
<backend name="worker">
<class>B2</class>
<instances>1</instances>
<options>
<dynamic>true</dynamic>
<public>true</public>
</options>
</backend>
</backends>
>From there you can access your application running within a backend
instance at the URL: *worker . (application id) . appspot . com *(ignore
the spaces). Then you can request URLs within your application as normal,
and the requests will be allowed to continue indefinitely.
You can also use the Modules service to run backend instances. Here's some
example code to try out:

With all of that said, a note of caution: this is at best a band-aid fix.
Normally, requests should not be lasting more than 60 seconds, especially
if you're just uploading form data. You may want to profile your app using
AppStats ( https://developers.google.com/appengine/docs/java/tools/appstats)
and see what is taking so long to run.
