WSO2 Data Services Server documentation

WSO2 Data Services Server (DSS) is a light-weight, enterprise-ready, fully-open source application server for Web services, based on the component-based WSO2 Carbon platform. The WSO2 Data Services Server is available under the Apache Software License 2.0 and is built on the Apache Axis2 framework. It incorporates leading open source components into a simple, easy-to-use, and high-performant package. Unlike many over-bloated, proprietary solutions, this package is a new platform that cuts out unnecessary layers, supporting the full WS-* stack in a clean and lean model. It provides a user-friendly web service interface for data stored in a range of data sources such as relational databases, CSV files, Microsoft Excel files, google spread sheets etc, which can be easily service-enabled using the WSO2 Data Services Server.

The WSO2 Data Services Server includes Web service specifications support such as WS-Addressing, WS-Policy, WS-ReliableMessaging, WS-Security and more, giving a secure, transactional and reliable infrastructure. Data can not only be exposed and accessed in a secured and reliable manner, but also made available for mashing-up with other Web services.

WSO2 Data Services Server is distributed in several convenient distribution packages, can be installed either as a standalone server or as part of a J2EE-compliant servlet container and accessed and managed through the simple user-interface. It also has many additional features inherited from the powerful WSO2 Carbon platform.
