Consuming SSL webservice in a GAE application

[Parth]

Hi,

I am developing a Python GAE which consumes a Web service to retrieve
some data to be shown to the user.
The Web service resides behind a firewall.

When I run the app from my local GAE environment on my development
machine, it works fine. But when I try to run it from the Hosted App
on GAE it show the following error.

File "/base/data/home/apps/<myAPP>/5.337678302407316965/ZSI/
client.py", line 532, in Receive
self.ReceiveSOAP(**kw)
File "/base/data/home/apps/<myAPP>/5.337678302407316965/ZSI/
client.py", line 415, in ReceiveSOAP
if not self.IsSOAP():
File "/base/data/home/apps/<myAPP>/5.337678302407316965/ZSI/
client.py", line 406, in IsSOAP
self.ReceiveRaw()
File "/base/data/home/apps/<myAPP>/5.337678302407316965/ZSI/
client.py", line 373, in ReceiveRaw
response = self.h.getresponse()
File "/base/python_dist/lib/python2.5/httplib.py", line 197, in
getresponse
self._allow_truncated, self._follow_redirects)
File "/base/python_lib/versions/1/google/appengine/api/urlfetch.py",
line 241, in fetch
return rpc.get_result()
File "/base/python_lib/versions/1/google/appengine/api/
apiproxy_stub_map.py", line 478, in get_result
return self.__get_result_hook(self)
File "/base/python_lib/versions/1/google/appengine/api/urlfetch.py",
line 325, in _get_fetch_result
raise DownloadError(str(err))
DownloadError: ApplicationError: 2

(I am using the ZSI framework to create the client to consume the
webservice).

Any help to resolve this would be highly appreciated.

Thanks,
Parth
