Apache Tuscany provides a runtime environment based on the Service Component
Architecture (SCA). SCA is a set of specifications aimed at simplifying SOA
application development. These specifications are being standardized by
OASIS as part of the Open Composite Services Architecture (Open CSA).
The Tuscany SCA Java 1.1 release adds a number of features including a JMS
binding, improved policy support and an implementation extension for
representing client side Javascript applications as SCA components.
