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 (http://incubator.apache.org/tuscany/). All the sample code in this article is licensed under the Apache License 2.0 (www.apache.org/licenses/LICENSE-2.0) and the resources with the article gives a link to the sample files. Both the Apache Tuscany and PHP SCA_SDO (http://pecl.php.net/package/sca_sdo) projects provide a free service oriented infrastructure for creating, packaging, deploying, and managing applications built with the SCA programming model. The SCA programming model itself is described by a set of specifications that are being developed by many vendors and individuals contributin... (more)

Building SOA with Tuscany SCA

Many articles have already been written about service-oriented architecture (SOA) and Service Component Architecture (SCA), for example, see references [1] and [2].

The recent Tuscany SCA version 1.0, which was released in Septe... (more)

SCATour-android: A front end to the "SCA Tour" scenario that allows you to search for trips direct from your Android phone. If you are reading here, you are interested on this... (more)
