Thanks Dietz for your earlier replies that helped me avoid some dead
ends.
I'm still trying to get the basics to work with Python server-side web
service.
Since tgwebservices is not compatible with tg 2.0, I need to use either
tg1.0 or a different technique.
It turns out that the approach I thought I could use of parsing the soap
request via a generic mod_python function is not working. More
accurately it reveals that I don't have sufficient understanding of
what's really happening and really need some help. While I know python
well, my soap experience is limited to clients and I built the entire
XML request via strings and the %s operator. Now that I have to do the
server, I cannot seem to get as far as receiving the soap xml and just
parsing it -- perhaps not elegant but adequate.
I know my client side test code is good because I use it with another
vendor's web service.
I've tried this code based on an existing mod_python implementation with
Python 2.4 and Apache 2.2
The HTTP works, just to verify I don't have a really dumb error
http://192.168.204.216/python/hrapi/RetrieveDataByXMLStream?a=3&b=abcd
returns
RetrieveDataByXMLStream method (()) {'a': '3', 'b': 'abcd'}
As expected
------------server side code -------------------
The mod_python code is installed at
/var/www/python/hrapi/index.py and is shown below (edited for brevity)
def RetrieveDataByXMLStream(req, *args, **kwargs):
req.content_type = 'text/plain'
text = 'RetrieveDataByXMLStream method (%s) %s' %
( str(args), str(kwargs) )
return text

I get the following error 'COMMERROR status=501, reason=Method Not
Implemented'
-----------------------Client side code------------------
class HTTPConnection(httplib.HTTPConnection):
def xrequest(self, method, url, body=None, headers={}):

From what I gather, that's a problem of Apache setup, not python or
mod_python. I had this yesterday when setting up a
subversion-over-apache-service, and got the same error. Being a proud
owner of an incredible efficient GC-algorithm in my brain, the knowledge
about the concrete reason immediatly vanished. So... I suggest you start
googling for apache, method not supported & mod_python, that should get
you started.
Only after you actually have you serverside-python-code running things
get interesting.
