WSO2 Data Services plugs into OSGi middleware


By David Worthington
May 8, 2009 — 
WSO2, a company that produces open-source SOA infrastructure, has made it possible for its data services software to interact with components of its Enterprise Service Bus (ESB).

WSO2’s Data Services 2.0, released earlier this week, has been reengineered to fit into the Open Services Gateway Initiative (OSGi) model for pluggable middleware, said WSO2 CTO Paul Fremantle.

OSGi implements a component model for the Java Virtual Machine to make Java more modular. WSO2 uses OSGi throughout its products, including its ESB. The company released updated editions of its SOA middleware in February that were built on OSGi.

"The key use case is enabling customers to take data services and put it together with components from the ESB, such as Extensible Stylesheet Language Transformations," Fremantle explained. "The pluggable scenarios are endless."

When WSO2 introduced Data Services in October 2008, it was only capable of straightforward mapping from data into services, he said. "That was a great starting point for users, but many wanted it the other way around. They had the service definition [Web Services Description Language] and wanted to tie the schema to data."

WSO2 Data Services 2.0 also introduces support for Event-Driven Architectures for graphical declarations of event sources and mediation for event delivery.

Data services may be created from relational databases such as IBM DB2, MySQL, Oracle Database and any other JDBC-compliant databases. Comma-separated value files and Microsoft Excel spreadsheets can also be sources of data services.
