What did you have in mind?

pySoap any good?

makes it easy to create python web based utilities,
and automatically exposes them as rest services

Hi Velappan,

Chapter 12 of "RESTful Web Services" (O'Reilly) has an example of a
web service implementation in Python (using the Django web framework).

http://oreilly.com/catalog/9780596529260/

Even if you don't buy the book, you can download the sample code for
the chapter.

Also, you could host your web-service on Google App Engine.

A couple of how-to articles, using XML-RPC and JSON-RPC:

http://appengine-cookbook.appspot.com/recipe/xml-rpc-server-using-google-app-engine/
http://code.google.com/appengine/articles/rpc.html

And a code sample with JSON-RPC:
http://code.google.com/p/gae-jsonrpc-example/

I hope the above helps!

Kevin.

Thanks Kevin!

I am about to go thru the article which you have sent to me.

My exact requirement is like , I have to fetch few data's from my
database and i have to convert my data's into XML format. I have done
the method to fetch the data's.

It would be great if you guide me to how to convert my data's into
XML format also how to configure my data's in apache.

i.e.) My web service will have a text field named user name and if I
enter user name it should list me the
project name for the particular user in XML FORMAT.

Thank you once again!

Hi Vela,

If you're following one of the articles and using Google App Engine,
you'll be leaving your Apache, your current server hosting and
database behind and adopting Google's infrastructure--in that case,
see the docs at http://appengine.google.com to get going.

That may be too radical an option...

If you're just using Django, you can set up Django with Apache (on
your own server, with whatever database you're using now). See the
extensive docs on www.djangoproject.com.

Here's another example of using Django with XML-RPC, which will output
XML using SimpleXMLRPCDispatcher:
http://code.djangoproject.com/wiki/XML-RPC

Good luck!

Kevin.

Hi Kelvin,

Thanks for your information will have look on those things. But we
have not used Django. We will try to do if it suits for us. Thanks
once again for your information all. Will work on those stuffs and
keep this post updated :)


Thanks & regards

Hi All,

I am in the process of creating Web service using SOAPpy.

I have created method to fetch few data from particular DB. i.e. From
Client side if I enter the user name, Server side will fetch the data
from DB and it will return back to client using SOAPpy. Here both the
Server side and Client side scripts are python files. In real time our
clients should be able to access our methods from any application,
like VC++ or .NET etc. How would we ensure that this webservice will
work for all environments?

It would also be great if you guide me to configure my web address
(For Ex: http://localhost:8080) in apache.


Thanks!

You can setup apache to run files that end in .py as cgi scripts but
there is a big overhead in starting the python interpreter every time
a page is requested. This can be overcome by using mod_python or
fastcgi, Django for instance has support for both of these methods and
might be simpler than writing your own mod_python handler.

If you're deploying to shared hosting this might also affect what you pick.

Testing. Lots of testing. Write once, test everywhere!

Good luck,

Kevin.
