Sans titre. XML Web Services in Visual Studio 2008 Tutorial. Introduction to Web Services Part 2: Architecture. In the previous article, the first in this series, we got a brief overview of Web Services.

We also touched on some simple concepts and took a quick look at the problem space that Web Services try to address in the overall context of enterprise applications. In this article, we will aim to set the overall direction for the rest of the articles in this series. We will cover the architecture of Web services and the technologies used in Web Services. Finally, we will study the steps involved in building a Web Services application. The underlying premise on which Web Services is based is a purely service-oriented architecture. Architecture of Web Services Client/server applications in use in the 80s and early 90s were primarily data-centric in nature. When we talk about service-oriented architecture for Web Services applications, quite a few things come up.

Hence, we can conclude that a basic service-oriented architecture for Web Services has: Click here for a larger image. Summary. Python-json-rpc – JSON-RPC. There are two implementations hosted on json-rpc.org: The old one which has support for JSON-RPC over TCP and HTTP.

And there is the rewrite of JSON-RPC for python, it is described in this document. You can browse the code or check it out using subversion from the bzr repository. The current implementation provides functionality for making JSON-RPC services available through CGI and through a mod-python handler. It also provides an easy to use proxy class for calling JSON-RPC services from python. Installation ¶ Download the source using bazaar. $ bzr checkout As root/administrator install the package running the provided setup script. $ cd trunk/python-jsonrpc $ python setup.py install If you do not wish to install the package you can simply copy the jsonrpc folder to where python can find it when it searches for modules to be imported.

Using the ServiceProxy class ¶ If everything worked you should now be able to call JSON-RPC services. Creating CGI based services ¶ #! #! ... Error handling ¶ About Windows Web Services. The Windows Web Services API is a layered API and it may be pictured as follows The WWSAPI is a layered API.

We expect most developers to target the Service Model, which is a method-based programming model. In the Service Model, the Service Host provides the server side programming model, while Service Proxy provides the client side programming model. Every layer exposes a set of APIs and types that can be used with APIs of that layer. [Traduction] Comment créer un protocol REST « Compléments pour les formations. Cet article de Joe Gregorio est paru, en anglais, sur XML.com le 1er décembre 2004, sous le titre : How to Create a REST Protocol Note : dans cet article inaugural de la nouvelle rubrique de Joe Gregorio, le Web Restful, il explique comment uiliser une architecture REST pour créer un protocole d’application avec les propriétés d’une application web.

Les futurs articles offriront des applications et analyses additionnelles sur REST. – L ‘Editeur en chef Si vous suivez les services web, vous devez avoir entendu parler de REST. REST est un style d’architecture qui peut être utilisé comme base pour la construction de service web. Récemment, il a été tenté de créer de tels services avec un succès mitigé. Qu’est-ce que REST ? Au fait, qu’est-ce que REST ? Une architecture logicielle est définie par une configuration d’éléments architecturaux – composants, connecteurs, et données – contraints dans leurs relations pour mettre en place un ensemble voulu de propriétés architecturales.
