<H1><A name="2.0-beta-Samplesdocumentation-"></A><FONT color="#003366"><B>Tuscany 2.0-Beta1 Samples</B></FONT></H1>
<P>The Tuscany samples are shipped with Tuscany binary and source releases (see the /samples directory). If you are using Tuscany from a release distribution then make sure you are looking at the documentation that corresponds to the samples as they stood at the time of the release. </P>
<P>The contents of the <A href="samples.html" title="Samples">Samples</A> page contains links to the various different versions of samples documentation.</P>
<P>In a distribution, the samples source code is found in the samples directory, directly under the root directory. The following sections are laid out to match the structure of the samples directory and its subdirectories.</P>
<P>If you're new to Tuscany SCA start with the getting-started. Samples are generally presented in the form on an SCA contribution (look for directories ending in "-contribution") or as a webapp (look for directories ending in "-webapp"). The directories getting-started, learning-more and applications all contain sample SCA contributions of increasing complexity. The running-tuscany directory describes the various different ways you can start the Tuscany runtime and install contributions. The extending-tuscany directory contains some examples of how to build new binding and implementation extensions for using in Tuscany.</P>
<P>In the following text we use <some_text> to mean you have to replace it with whatever is appropriate in your environment. For example <tuscany_bin_distro> means the directory in which you install the Tuscany binary distribution.</P>
<P>Instructions are colour coded as follows:</P>
<DIV class="panel" style="background-color: pink;border-width: 1px;"><DIV class="panelContent" style="background-color: pink;">
<P>Instructions in pink boxes are for the Ant user</P>
</DIV></DIV>
<DIV class="panel" style="background-color: silver;border-width: 1px;"><DIV class="panelContent" style="background-color: silver;">
<P>Instructions in silver boxes are for the Maven user</P>
</DIV></DIV>
<P>Note. As some of these samples create and use local network connections you may need to configure your firewall, if you are running one, to allow the test to run successfully. </P>

<P>SCA defines a concept called a Contribution which is the way that SCA composite applications are packed for deployment. See <A href="sca-introduction.html" title="SCA Introduction">SCA Introduction</A> for more information on SCA concepts.</P>
<P>The getting-started samples consist of simple SCA contributions that you can build and run as your first step to getting up and running with the Tuscany SCA Java runtime.</P>
<P>You can build the sample contributions with either Maven or Ant and the running-tuscany directory contains information about the various ways you can start Tuscany and run these contributions.</P>
<H3><A name="2.0-beta-Samplesdocumentation-helloworldcontribution"></A>helloworld-contribution</H3>
<P>This is a simple SCA contribution. It describes a composite application with a single component, HelloWorldComponent, implemented in Java. The component's Java implementation provides service "business logic" for saying hello to a person whose name is supplied as input to the service. The component is described in a composite called helloworld.composite as follows:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

</component>
</composite>
</PRE>
</DIV></DIV>
<P>The contribution also contains a composite called helloworldws.composite which describes a component, HelloworldWSComponent, that uses the same implementation but uses a web services binding:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

<binding.ws />
</service>
</component>
</composite>
</PRE>
</DIV></DIV>
<P>This gives us a number of options for interacting with the components in this application. </P>
<P>Firstly there is a JUnit test inside this project called HelloworldTestCase.java. This starts the Tuscany runtime and loads the contribution. It then talks to the HelloworldComponent over the default SCA binding (binding.sca) using a local Java proxy.</P>
<P>Secondly the HelloworldWSComponent exposes a service with a web services binding. You can talk to this component using your favourite web services client. You can retrieve the WSDL for the web service automatically (see later)</P>

<P>TODO</P>
</DIV></DIV>
<DIV class="panel" style="background-color: silver;border-width: 1px;"><DIV class="panelContent" style="background-color: silver;">

</DIV></DIV>
</DIV></DIV>
<P>To access the web service that the HelloworldWSComponent exposes we have to keep the runtime runntime running. </P>
<DIV class="panel" style="background-color: pink;border-width: 1px;"><DIV class="panelContent" style="background-color: pink;">
<P>To run the sample Ant so that you can access the web service do the following:</P>
<P>TODO</P>
</DIV></DIV>
<DIV class="panel" style="background-color: silver;border-width: 1px;"><DIV class="panelContent" style="background-color: silver;">

<P>The samples found in the contributions below illustrate more of SCA and Tuscany's features in action.

<P>This sample extends the calculator sample by replacing the local wired connections with RMI bindings. Instead of local add, subtract, multiply and divide components, an RMI service implementation now provides the add, subtract, multiply and divide interfaces and is hosted as an RMI server. References specified in the .composite file include an RMI binding which targets<BR>
this RMI server.</P>

<H3><A name="2.0-beta-Samplesdocumentation-distributedosgi"></A>distributed-osgi</H3>
<P>These samples demonstrate the execution of Tuscany contributions in a OSGI environment. In particular the two bundle project in this directory define calculator objects that communicate with one another using the mechanisms defined in the OSGi remote services specifications. Here the Tuscany SCA runtime provides dynamic service discovery functionality. The calculator objects are registered as services directly with the OSGi bundle context by the bundle activator. Under the covers SCA provides the remote service disovery features that allow OSGi registered service to discover and communicate with one another across two JVMs. </P>
<P>To run the sample each bundle must be build using maven and then loaded into a separate OSGi environment into which the Tuscany SCA runtime has already been installed (See "osgi" under running-tuscany)</P>

<P>Running something in Tuscany requires one or more contributions, and a method of launching the contributions to make the services they provide available. The sections below describes various means of launching contributions with the Tuscany SCA Java runtime. It's not important that you try all of these but they show you what's possible and hopefully show you how to use Tuscany in an environment that makes sense to you.</P>
<P>Some of the running-tuscany sub-directories just contain a README that gives you instructions. For example, maven just tells you how to configure and run contributions using the maven-tuscany-plugin. Others contain code. For example, embedded-jse contains simple Java launchers that show you how to start some of the sample contributions from a Java program.</P>
<P>The sample contributions in getting-started and learning-more should work regardless of which approach you adopt. However some approaches, like embedded-jse, don't have launchers for every single sample contribution.</P>

<H3><A name="2.0-beta-Samplesdocumentation-eclipse"></A>eclipse</H3>
<P>To import sample contributions into Eclipse you first need to import the Tuscany runtime. You then need to import the sample contribution into Eclipse as a project. Instructions for doing both of these things can be found here</P>
<P><A href="http://tuscany.apache.org/import-existing-tuscany-sca-projects-into-eclipse.html" class="external-link" rel="nofollow">http://tuscany.apache.org/import-existing-tuscany-sca-projects-into-eclipse.html</A></P>
<P>Note. these instructions refer to our 1.x code base but it holds true for our 2.x code base.</P>
<P>Once you have a contribution imported into Eclipse and cleanly compiling against the Tuscany runtime jars you probably want to be able to run and debug it. The easiest way to do this is with a simple Java launcher. If you import the running-tuscany/embedded-jse project into Eclipse you'll see a number of such launcher programs which you can copy to launch the contribution(s) of your choice. Alternatively you can add a JUnit test case to the contribution that starts Tuscany and launches the contribution. See maven-junit as an example of how to do this.</P>
<H3><A name="2.0-beta-Samplesdocumentation-embeddedjse"></A>embedded-jse</H3>
<P>This directory contains sample java launchers for the some of the Tuscany sample contributions from the learning-more directory. It shows you how to embed the Tuscany runtime in a Java program. To make you're own launchers simply copy and existing one and change the details of the contribution being loaded. You'll note that the same launcher code is used inside the contribution unit test demonstrated by maven-junit.</P>

<H3><A name="2.0-beta-Samplesdocumentation-maven"></A>maven</H3>
<P>Maven can be used to install contributions. Tuscany has a special plugin (maven-tuscany-plugin) that makes this happen. Look for contributions that have the following configuration in their pom.xml file:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">
<PRE class="code-java">
<plugin>
<groupId>org.apache.tuscany.maven.plugins</groupId>
<artifactId>maven-tuscany-plugin</artifactId>
<version>2.0-SNAPSHOT</version>
</plugin>
</PRE>
</DIV></DIV>
<P>For contributions that have this, for example, learning-more/binding-sca/contribution-calculator, do the following</P>
<P>cd samples/learning-more/binding-sca/contribution-calculator<BR>
mvn tuscany:run</P>
<P>This will install the contribution in the Tuscany runtime, start the composite it contains, and then wait. At this point you can use<BR>
other clients to send messages to services that the running SCA applcation exposes, for example, try learning-more/sca-client/calculator-scaclient.</P>
<H3><A name="2.0-beta-Samplesdocumentation-mavenjunit"></A>maven-junit</H3>
<P>Maven will run JUnit tests found in a module's src/test/java directory automatically. If you use embedded-jse style code in the JUnit test to install a contribution and start any composites it contains they you can unit test your contributions. This directory contains a contribution and a unit test which installs the contribution using very similar code to that found in embedded-jse.</P>
<P>To run the contributions unit test do the following:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">
<PRE class="code-java">
cd maven-junit/calculator-contribution
mvn
</PRE>
</DIV></DIV>
<H3><A name="2.0-beta-Samplesdocumentation-mavenjunitosgi"></A>maven-junit-osgi</H3>
<P>You can use a special Tuscany Maven plugin (maven-osgi-junit-plugin) to unit test contributions in a JUnit environment. This relies on adding some configuration to the Maven pom.xml. For example, if you look in maven-junit-osgi/calculator-osgi you'll see:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

<P>This configures the maven-osgi-junit-plugin to use the tuscany-node-launcher-equinox to install the contribution represented by the calculator-osgi directory. As an alternative to this configuration you could use the contents of tuscany-node-launcher-equinox directly in your JUnit test to launch the Tuscany runtime using OSGi.</P>
<P>To run the contributions unit test do the following:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

<LI>launch the OSGi container itself</LI>
<LI>load the Tuscany runtime bundles (all our jars are bundles) into the container</LI>
<LI>install a contribution packaged as an OSGi bundle</LI>

<P>The shell can also run as a Webapp. To try it install target/scashell.war in<BR>
a Web container, point your Web browser to <A href="http://localhost:8080/scashell" class="external-link" rel="nofollow">http://localhost:8080/scashell</A><BR>
and try the links on that page.</P>
<H3><A name="2.0-beta-Samplesdocumentation-webapp"></A>webapp</H3>
<P>Tuscany can be embedded inside a webapp alongside one or more SCA contributions. To execute sample webapp based contributions (contributions that have webapp at the end of their name) you can build the contribution using maven and then copy the resulting war file to your container of choice</P>
<P>For example, for binding-jsonrpc/contribution-calculator-webapp, do the following:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">

</DIV></DIV>
<P>As an alternative, sample webapp based contributions can be run within Jetty directly from Maven, look for webapp contributions that have the following configuration in their pom.xml file:</P>
<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent">
