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
