Introduction to Web Services Development with Websydian

Using TransacXML Web Services¹⁾ are implemented extremely fast. Business logic is easily implemented and fully integrated, as high-level support for SOAP and detailed control of Web Service implementation allows Web Services to be implemented "out of the box", while still allowing for advanced and detailed control of the implementation.

The entire development and maintenance process is encapsulated in one development environment, and the developer can be productive from day one without the need for time consuming knowledge acquisition of XML and SOAP technologies.

The globalization has created an increasingly complex and dynamic business environment that forces companies to focus on their core competences and to outsource the areas of their value chain where they do not possess sustainable competitive advantages. This in turn increases the demand for real time intercompany business communications between disparate IT systems. A demand Web Services can fulfill in a commercially viable way!

As shown below a generic web service implementation communicates across the Internet and across firewalls. The party initiating a web service dialog is called the Subscriber, while the party accepting requests is called the Publisher. Seen from the outside, both the Subscriber and the Publisher are implemented as "Black Boxes".

The Websydian TransacXML Developer enables development of both parties involved in a Web Service. In the example below both parties are implemented using Websydian TransacXML Developer.

TransacXML adds a Web Service Layer to standard Websydian applications, allowing developers to Web Service enable existing applications or develop new Web Service applications from scratch.

Before a web service is implemented it must be taken into consideration whether to use the DWA or the CWA architecture in Websydian. For more information about CWA and DWA please refer to the following documents:
