3. Apache Tuscany
> Apache Tuscany provides a component based
programming model which simplifies development,
assembly and deployment and management of
composite applications in SOA.
> Apache Tuscany implements SCA standards
defined by the OASIS OpenCSA and also provides
extensions based on real user feedback.

5. The power of Tuscany/SCA
> Quick prototype for PoC to convince your boss in
hours
 Mock up new functions (POJOs)
> Reuse existing assets (Java classes, BPEL, Spring,
JEE, OSGi)
> Talk to external services transparently
 (WS, RMI, CORBA, EJB, JMS, …)
> Expose services to other clients transparently
 (WS, JSONRPC, FEED, RMI, CORBA …)
> Built-in interaction patterns:
 Req/Res, Oneway, Callback
> Run and debug directly within the IDE
