<h3>Tuscany Webapp Sample</h3>
<h4>Overview</h4>
<p>This sample illustrates how to use Apache Tuscany to run a SCA composite inside a
web application. It describes how to run it on Apache Tomcat but the application
should be portable to other containers such as Jetty or commmercial servers.</p>
<h4>Location</h4>
<p>This sample is located in the <a href=
".">samples\webapp\webapp</a> 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>
<li><a href="http://tomcat.apache.org/download-55.cgi" target=
"_blank">Apache Tomcat 5.xx</a> latest version binary core
distribution. </li>
<li>This sample reuses the composite from the <a href= "../../standalone/calculator/readme.html" target="_blank">calculator sample</a>
so that sample must have beed built before building this sample.</li>
</ul>
<h4>Building</h4>
<p>To build the sample issue :</p>
<pre>
<code>mvn</code>
</pre>
<p>This should result in the creation of the war file
<span style="font-weight: bold;">target\sample-webapp.war</span></p>
<h4>Setup</h4>
<p>If you have enabled remote deployment in Tomcat by adding the
line:</p>
<p><code><user username="admin" password=""
roles="manager"/></code></p>
<p>into <span style="font-style: italic;"><tomcat
dir></span>\conf\tomcat-users.xml you can deploy the WARs to
Tomcat using the tomcat-maven-plugin:</p>
<p><code>mvn tomcat:deploy</code></p>
<p>Alternatively you can copy the WAR files to Tomcat's webapps
directory. Copy <span style=
"font-weight: bold;">target\sample-webapp.war</span>
<span style="font-style: italic;"><tomcat
dir></span>/webapps/.</p>
<h4>Running</h4>
<p>Start the tomcat server by issuing the following command ind
the <span style="font-style: italic;"><tomcat
dir></span>\bin directory:</p>
<p><code>startup</code></p>
<p>Once you've started your web server, open a browser and go to sample-webapp page at
<a href=
"http://localhost:8080/sample-webapp/" target=
"_blank">http://localhost:8080/sample-webapp/</a> and you should see a web page displaying:</p>
<samp>
