This is a simple example that will show you how to develop a Web Servic client and service starting from a WSDL document. The flow of this example is very similar to the hello example with RMI because RMI and WSDL have same function as a contract between client and server. Again, the development process can be divided into the following steps:

The WSDL Specification

Using WSDL in a UDDI Registry

The following example use's AMFPHP and nusoap to consume two different web services inside of flash. Below is a brief overview, however this application is meant mainly for sample code.

Web Services Introduction

Introduction to WSDL

WSDL is a specification defining how to describe web services in a common XML grammar. WSDL describes four critical pieces of data:

A Profile-based class hierarchy of service categories.

A pdf which covers demystifying service oriented architecture.

This tutorial describes the ServiceDesigner sView service, and the service location web site Salcentral.com.

The SOAPworX code generator can generate client and server code separately, or at the same time. In this example, we will generate both the client and the server.

The following example is similar to the preceding example, but instead of specifying the city argument in the URI of the resource, the argument is passed when calling the resource.

In the web community communications protocols and message formats are standardized. This implies that the communications can be described in some structured way. This need is met by WSDL which defines XML syntax for describing web services as a collections of communication endpoints able to exchange messages.

Introduction to WSDL

The Web Services Description Language (WSDL) is an industry standard XML vocabulary used to describe and expose services for client consumption.

WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint.

This paper contributes to the discussion on using WSDL as a business service description in the UDDI Registry. It presents an analysis of possible techniques and evaluates their advantages and drawbacks from a technical point-of-view. The purpose of this paper is to introduce Idoox's proposal for public review.
