WSO2 Mashup Server, v0.2 Release Note - 4th October 2007

"Create, deploy, and consume Web services Mashups in the simplest fashion"

The WSO2 Mashup Server is a powerful yet simple and quick way to tailor Web-based information to the personal needs of individuals and organizations.

It is a platform for acquiring data from a variety of sources including Web Services, HTML pages and feeds, and process and combine it with other data using JavaScript with E4X XML extensions. The result is then exposed as a new Web service with rich metadata and artifacts to simplify the creation of rich user interfaces.

The WSO2 Mashup Server will form the backbone of a become an ecosystem of community-developed services that will broaden the palette of capabilities for mashups and distributed applications.

WSO2 Mashup Server is released under the Apache License v2.0

Known Issues

• Management Console was tested only on IE 6/7 & Firefox 1.5/2.0.
• Inter-service dependencies using the dynamically generated stubs may give deployment time errors. Workaround would be to save a local copy of the stub in to the dependent service.

• Stubs drop items from Array and Object return values when no annotations are used (MASHUP-346).

Future Directions
