5 SCA V1.0 SCA specification development started life in OSOA a Consortium of industry vendors. The specs reached v1.0 here Apache has an incubator project called Tuscany which hosts the multi-lingual open source implementations for SCA v1.0 SCA specification development has now moved to the OASIS Open Composite Service Architecture section 5 WebSphere UK User Group 3/11/2008

8 What is Apache Tuscany Some words from the project charter: open-source software for distribution at no charge to the public, that simplifies the development, deployment and management of distributed applications built as compositions of service components. These components may be implemented with a range of technologies and connected using a variety of communication protocols. This software will implement relevant open standards including, but not limited to, the SCA and SDO standards defined by the OASIS OpenCSA member section."

9 Apache Tuscany - History Project created in Dec 2005 in Apache incubator Initial code contribution from BEA and IBM 8 SCA implementation releases 09/ release (first implementation of SCA spec v1.0) 12/ bug fix release 01/ release, JMS binding and improved policy support Growing user and developer community

10 Tuscany Modules There is a wide selection of modules in various stages of development. Component Implementation Types BPEL DAS Java Notification OSGi Resource Script (Groovy, Ruby, Python, Javascript) Spring XQuery Hosting Jetty Tomcat WebSphere Geronimo OSGi Binding Types Ajax Feed (RSS, Atom) JMS JsonRpc Notification OSGi Rmi SCA Ws/Axis2 XQuery Databindings Axiom Jaxb Json Saxon Sdo XmlBeans There is lots more to be done. If you are interested in Open Source consider yourself invited to join the Tuscany project 10 WebSphere UK User Group 3/11/2008

11 Extensibility Tuscany Java SCA is based on an extensible, modularized architecture that can easily be extended. There is a stable SPI defined for adding new technologies, e.g. bindings, databindings, implementations and hosting support. If you find that SCA doesn t support your technology of choice check with the Tuscany mailing list (see How to find out more ) as it may already be in development and you could help develop or test it. Alternatively it s not too hard to add new ones yourself and you could come and help Tuscany build it All contributions are most welcome! 11 WebSphere UK User Group 3/11/2008
