<H1>Tuscany SCA Native Samples - REST Calculator Sample</H1>
<P>This is a very simple sample to show how an SCA composite can wire
together two Ruby components to implement a Calculator service and expose
that service as a REST Service running under Apache HTTPD.
</P>
<P>The REST Calculator sample requires the following extensions:
<UL>
<LI><A HREF="../../doc/RestExtension.html">REST Service & Reference Extensions</A></LI>
<LI><A HREF="../../doc/RubyExtension.html">Ruby Extension</A></LI>
</UL>
Please follow the documentation to ensure you have these extensions built and installed
on your system</P>
<P>There are three sub projects in this workspace:</P>
<UL>
<LI>sample.calculator<BR/>
This contains the Ruby scripts and SCDL artifacts for the SCA Calculator
composite implementing the sample Calculator.
</LI>
<LI>sample.calculator.restclient<BR/>
A sample client which does a local call to the Calculator service.
</LI>
<LI>httpserver<BR/>
A minimal configuration for the Apache HTTP server used to host the
REST service as well as scripts to start and stop the server.
</LI>
</UL>
<P>Additionally, there is the sample.calculator.app.composite file. This
describes the configuration of the SCA Calculator composite deployed to the SCA
runtime.
