The Open SOA collaboration has published a 0.9 draft of the SCA Java EE Integration specification.
This specification describes the integration of Java EE applications and Java EE components with SCA - providing for the integration of existing applications and components into the wider SOA world of SCA, and also providing means to extend existing applications and components with new capabilities supplied via SCA composition.
The SCA Java EE Integration draft specification can be found on the SCA Project Specifications page
The Open SOA collaboration welcomes feedback on this draft level specification, prior to the publication of a V1.0 of the specification. We are particularly keen to hear from implementers of SCA runtimes and also from end users who are building applications using SCA. You can provide feedback using the Feedback link in the menu on the left.
