<h3>Tuscany Simple Callback Sample</h3>
<h4>Overview</h4>
<p>The Tuscany Simple Callback sample illustrates a simple asynchronous
callback scenario, similar to the one illustrated in the Client
and Implementation Model for Java SCA specification. Two atomic
components are wired together that implement a bi-directional
interface. The component definitions are given implicitly by
the Java code and the use of <code>@Callback</code> annotations.</p>
<h4>Location</h4>
<p>This sample is located in the
samples\standalone\simplecallback 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-simplecallback.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-simplecallback.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>Work thread Thread[pool-1-thread-1,5,main]
<br>Result: -> someMethod -> receiveResult
</samp>
