<h2>Tuscany Hello World WS Sample</h2>
<h3>Overview</h3>
<p>The Tuscany hello world ws sample shows using the Tuscany SCA
runtime in a Tomcat environment providing a web service.. </p>
<h3>Setup</h3>
Set up your server as described in the <a href="http://wiki.apache.org/ws/Tuscany/TomcatIntegration" target="_blank">Tomcat Setup</a>. If
you are not configuring with the acceptance test the server, you will need to add <span style="font-weight: bold;">helloworldws-SNAPSHOT.war</span>
to your Tomcat's webapp directory.
<h3>Running</h3>
This service can be invoked by either the Tuscany SCA <a target="_blank" href="../helloworldwsclient/readme.htm">helloworldwsclient</a>
sample or <a href="../helloworldaxis/readme.htm" target="_blank">hello
world Axis sample's</a> client sample.<br>
