<h3>Tuscany Inner Composite Sample</h3>
<h4>Overview</h4>
<p>The Tuscany Inner Composite sample illustrates an asynchronous
callback scenario across atomic components contained in separate
composites. The containing (inner) composites are themselves contained in
a single composite and an explicit wire connects them. Thus, the
corresponding composite reference and service do not specify a
binding (not even binding.sca), and the connection and invocation
occur in the same process.</p>
<h4>Location</h4>
<p>This sample is located in the
samples\standalone\inner.composite directory. All the
following commands should be issued while working in the sample
directory.</p>
<h4>Prerequisites</h4>
<p>Obtain the following prerequisites and install according to
their documentation.</p>
<ul>
<li><a href="http://java.sun.com/javase/downloads/index.jsp"
target="_blank">JDK 5.0</a></li>
<li><a href="http://maven.apache.org/download.html" target=
"_blank">Maven 2.0.4</a></li>
</ul>
<h4>Building</h4>
<p>To build the sample issue :</p>
<pre>
<code>mvn<br></code>
</pre>
<p>The result after executing is in the <span style=
"font-weight: bold;">target</span> subdirectory the <span style=
"font-weight: bold;">sample-innercomposite.jar</span></p>
<h4>Setup</h4>
<p>Set up the Tuscany standalone runtime environment using the
following command:</p>
<pre>
<code>mvn dependency:unpack <br></code>
</pre>
<p>After completion there should be a <span style=
"font-weight: bold;">target\distribution</span> subdirectory
created that has the Tuscany standalone runtime.</p>
<h4>Running</h4>
<p>Execute the following command: (<span style=
"font-style: italic;">cut and paste to command line</span>)</p>
<pre>
<code>java -jar target/distribution/bin/launcher.jar target/sample-innercomposite.jar</code>
</pre>
<h4>Results</h4>
<p>The sample when run should simply display to the standard
output:<br>
<samp>
<br>Main thread Thread[main,5,main]
<br>Source: Client.main -> Source.clientMethod
<br>Source: Client.main => Source.clientMethod
<br>Target: Client.main => Source.clientMethod
<br>Work thread Thread[pool-1-thread-2,5,main]
<br>Result: Client.main => Source.clientMethod -> Target.someMethod
<br>Target: Client.main -> Source.clientMethod
<br>Work thread Thread[pool-1-thread-3,5,main]
<br>Result: Client.main -> Source.clientMethod -> Target.someMethod</samp>
</p>
