Article: What is SCA ?

Haleh, Simon Laws and Raymond's article explaining some details of Service Oriented Arquiteture (SCA) has just been published at JDJ.

What Is SCA?
— Service Component Architecture (SCA) is a simple model for creating service-oriented applications. This article highlights the benefits of SCA and introduces SCA concepts by walking through an example. The example has been developed using the Apache Tuscany open source project. All the sample code in this article is licensed under the Apache License 2.0, and the resources with the article gives a link to the sample files. Both the Apache Tuscany and PHP SCA_SDO projects provide a free service oriented infrastructure for creating, packaging, deploying, and managing applications built with the SCA programming model.

Declarative DAS - Integrating SCA and DAS

Luciano Resende recently posted in his blog an entry about his ideas aroundDeclarative DAS :

Declarative DAS : Extend the SCA programming model to expose services that interact with a persistent layer in a declarative fashion hiding the implementation details from the service developer.It’s all about simplicity, allowing a service to be defined without explicitly coding the persistence layer.

Take a look, and express your comments.

SCA Standalone samples : Building, Running and Debugging

Luciano Resende recently posted a nice entry about building, running and debugging SCA Standalone applications.

"Service Component Architecture (a.k.a SCA) have two types of assembly distributions: Standalone and webapps.

In this post, I'll describe how to build, run and debug standalone applications based on Tuscany SCA sample applications."
