The WSO2 Mashup Server is a platform for hosting mashups written in JavaScript with the E4X extension. These mashups can consume data from various sources such as feeds, HTML pages, external Web services, databases (via Data Services), Excel files (via Data Services) etc. These newly created mashups are then exposed as Web services in return.
In this Screencast, Jonathan Marsh, Director of Mashup Technologies for WSO2, demonstrates how to create a simple hello-world Web service using only the WSO2 Mashup Server and Notepad. A simple Javascript function is deployed as a Web service, WSDL and other metadata is automatically generated, and then the service is tested using the Mashup Servers try-it page. The service also shows how to quickly construct XML using the E4X Javascript extensions, and how to apply simple annotations documenting the operations and declaring parameter types.
