h1. Tuscany SCA Java

Tuscany Java SCA provides the infrastructure for easily developing and running 
applications using a service-oriented approach. This lightweight runtime is 
designed to be embedded in, or provisioned to, a number of different host 
environments without much effort.

SCA applications run within an SCA Domain, a logical concept that bounds all of 
the components within an application. In Tuscany Java SCA the SCA domain 
can run on a single JVM or it can run across multple JVMs without modifying the 
the way that each component is described.

In this way your SCA application can be run in one place or can be distributed 
out while relying on the power of SCA to ensure that messages are delivered
to the right component regardless of the configuration. 

At the very high level, Java SCA can be divided into core and extensions. The 
core supports the SCA assembly model, Tuscany value-add features and simple 
extension point to add extensions. Tuscany SCA Java extension points allow any 
binding type, implementation types(programming model), policy and data binding 
to be easily added to it. The Tuscany community has contributed the extensions 
that are shown below. An extension becomes available for the latest Tuscany 
release as volunteers test and enhance the extension to work with that release. 

||Implementation Types||Bindings||Data Bindings ||Interface Types||
|Java components
Spring assemblies
Scripting with JSR 223(JavaScript, Groovy, Ruby, Python & XSLT)
BPEL (a prototype using Apache ODE)
XQuery |Webservice using Apache Axis2
JMS (tested with Apache ActiveMQ)
JSON-RPC 
EJB
Feed|JAXB
SDO
Axiom
Castor
XMLBeans|Java
WSDL 1.1| 

SCA Java is integrated with Tomcat, Jetty and Geronimo(in progress).

~Copyright © 2006, The Apache Software Foundation Apache Tuscany is undergoing 
incubation at The~ ~[~Apache Software Foundation 
(ASF)~|http://www.apache.org]~~, sponsored by the Web Services PMC. Incubation 
is required of all newly accepted projects until a further review indicates 
that the infrastructure, communications, and decision making process have 
stabilized in a manner consistent with other successful ASF projects. While 
incubation status is not necessarily a reflection of the completeness or 
stability of the code, it does indicate that the project has yet to be fully 
endorsed by the ASF.~
