This user guide helps you learn more about SCA through Tuscany. It starts with building a simple application and progresses into more advanced features through references to samples that reside in Tuscany. </P> + +<P>Before we start, let's emphasise that it is Tuscany's goal to provide an implementaiton that avoids imposing rules and requirements on how you write your applications. In fact the goal is to let you write application code without being concerned about the technology you choose or the environment in which it will be used. You focus on your business logic and Tuscany infrastructure will handle the rest. </P> + +<H2><A name="placeholderfortheolduserguidepage-"></A><A name="placeholderfortheolduserguidepage-CreateYourFirstApplication"></A><DIV class="" style="background-color: #C3CDA1;">Create Your First Application</DIV> +</H2> +<P>This simple exercise provides you with a hands-on experience for creating an SCA calculator application.

This application is developed in Eclipse enviromment and uses more advanced features that are offered in Tuscany.

The runtime itself is made up of many of the modules that are present in the modules directory of the Tuscany SCA Java distribution. As you might expect there are functions that read XML, create an in memory mode model of the SCA assembly, create the components and wire them together ready to process incoming messages. All of these functions are wrapped up in a Node. A node is configured using SCA contributions and will run a single composite. When running standalone the node also defines the scope of component services that references can target by name. SCA defines the term Domain to describe this scope. <SPAN class="error">Unable to render embedded object: File (calculator2.png) not found.</SPAN><BR> +A node runs within a single JVM. A JVM can run many Nodes.</P> + +<H3><A name="placeholderfortheolduserguidepage-hostembedded"></A>host embedded</H3> +<P>For a long time in Tuscany we have had a modules called <A href="sca-java-hostembedded.html" title="SCA JAVA host.embedded">host.embedded</A> that contains the code required to get the runtime up and running in standalone configuration. This was developed before the distributed domain support was added but the main interface here is called an SCADomain. It's just a very small domain with only one node inside it. You can't see the node and you configure and access it via the SCADomain interface. The majority of samples and tests use this today. However the new SCA Node implementation can work in both standalone and distributed configuration so may be more appropriate in situations other than the simple Tuscany samples and tests. We will convert more samples ant tests to this approach over time to show the benefit of using the node implementation.</P> + +<H3><A name="placeholderfortheolduserguidepage-TuscanySCANodeImplementation"></A>Tuscany SCA Node Implementation</H3> +<P>Available from release 1.2 there is a new domain/node implementation. The node part of this can be run either stand alone or as part of a distributed domain. Most of the sample and test code has not started using this implementation yet and there may be more changes to the API.</P> + +<H4><A name="placeholderfortheolduserguidepage-CreatingandConfiguringNode"></A>Creating and Configuring Node</H4> + +<P>Creating a node in code is straightforward.

SCA wires can be used to connect components within a single SCA Domain.</P> + +<P>From the calculator sample you can see that the wires between the component references and services, formed by adding a target component name to a reference, are resolved inside an SCA domain.

A domain can consist of more than one composite and wires can run between components defined in the composites. The SCA Domain describes the boundary within which target component services can be located.</P> + +<P>To connect to services outside of the SCA Domain (whether they be services provided by SCA or by other means) you configure an explicit binding, for example, lets assume that the AddServiceComponent is a non-sca web service out there on the network somewhere.

Configuration must be provided which tells the workspace where the nodes are that are going to run the composites and which composites they will run. Based on this information the domain manager makes an atom feed available for each composite that is deployed to a node. The node to which the composite is assigned must read the correct atom feed in order to configure itself by downloading the composite to run and the contributions required provide the artifacts required by the composite.
