WSO2 Offers New Web Services Framework

The company's new offering integrates the Apache Java engine into the Spring Framework.

WSO2 is releasing the WSO2 Web Services Framework for Spring 1.0, also known as WSO2 WSF/Spring 1.0.

The WSO2 WSF/Spring open-source framework integrates the Apache Axis2 Java Web services engine into the Spring Framework. The Spring Framework is a lightweight Java development framework for building enterprise applications. WSO2's new offering, announced March 31, enables Spring users to control Axis2 from within the Spring configuration model. The technology provides developers with a Web services engine-with the security and reliable messaging required for an SOA (service-oriented architecture)-that fits into their Spring Framework environment and allows them to use any of their favorite Spring user interfaces.

Other key features of WSO2 WSF/Spring 1.0 include support for the WS-* stack, including WS-Addressing, WS-Policy WS-Security, WS-SecurityPolicy, WS-ReliableMessaging, WS-Eventing, and SOAP (Simple Object Access Protocol) Message Transmission Optimization Mechanism. The product also features Inversion of Control container support, automated WSDL (Web Services Description Language) generation, querying service support, and method exclusion in Spring beans.

The WSO2 Web Services Framework for Spring 1.0 is released under Apache License 2.0 and is based on the open-source Apache Axis2 Java Web services engine.

Also, WSO2 officials said WSF/Spring 1.0 is being used to create Web services within the Grails Web application framework, which is based on the Groovy language. The product also is suited to this environment because Grails was developed using Spring, company officials said.

"The Axis2 for Grails plug-in would have been a lot trickier had it not been for WSO2's efforts in providing Axis2 for Spring integration through WSF/Spring," said Graeme Rocher, project lead for Grails and chief technology officer at G2One.

According to Sanjiva Weerawarana, CEO of WSO2, enterprises looking to expand the reach of SOAs will need businesses to use a range of Web application frameworks.

Moreover, the WSF/Spring 1.0 technology enables developers to choose either a "code-first" or "contract-first" approach to building Web services. Spring supports Web services creation through the contract-first model, where users start with X M L schema and WSDL definitions of their service. Weerawarana said WSF/Spring 1.0 complements this approach by adding code-first Web services support, in which users can start with existing Spring beans and offer them as Web services.
