Copies of the +specifications may be obtained from http://www.osoa.org. + +*** Please Note that extension SPIs are subject to change in future alpha and beta releases *** + +Release Features +---------------- +A goal of the release has been closer alignment with the SCA specifications, and in particular, +the implementation of new Java annotations and APIs introduced in the 1.0 version. +New features include: + +- Support for full composite recursion (N-levels) +- Improved and simplified non-blocking operations +- Support for SCA 1.0 conversational callbacks, including synchronous operations +- Support for many of the SCA 1.0 Annotations and APIs, including: scopes, + conversational annotations, ComponentContext, callback annotations, +- Support for SCA 1.0 autowire +- Support for service target syntax +- Support for reference promotion syntax (multiple level promotion is not yet implemented + but planned for the next release) +- Support for exception formatting +- Improved exception handling +- Reduced disk and memory footprint + + +This release also includes significant architectural enhancements and refactors. +Much of this work has been focused on simplification of the core architecture. +In addition, changes have been introduced to support federated service networks +and multi-VM wiring. It is expected that those features will be added in the next alpha release. + +- Greatly simplified wiring architecture, including elimination of inbound and outbound wiring +- Support for sparse component trees distributed across multiple-VMs +- Improved autowire support including changes to enable federated autowire in the next release +- Introduction of a ComponentManager +- Refactored Connector +- Refactored Component interface and hierarchy +- Increased test coverage (~70%) +- An early implementation of federated assembly changeset marshalling + + +In bocca al lupo! +The Tuscany Team |
