<H1>Tuscany SCA Native Samples - HTTPD BigBank Sample</H1>
<P>This sample implements the "Simplified BigBank" scenario. A whitepaper describing
the scenario based on the SCA 0.9 Assembly specification can be found
<A HREF="http://www.osoa.org/display/Main/SCA+-+Previously+Published+Specifications">here</A>.
This is a more modular version of the original Bigbank app, with the account
service and the account data service are in different composites.
</P>
<P>The HTTPD BigBank sample requires the following extensions:
<UL>
<LI><A HREF="../../doc/RubyExtension.html">Ruby Extension</A></LI>
<LI><A HREF="../../doc/Axis2CWSExtension.html">Axis2/C Web Services Extension</A></LI>
<LI><A HREF="../../doc/SCAExtension.html">SCA Binding 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>bigbank.account<BR/>
This contains the source code and SCDL artifacts for the SCA HTTPD BigBank
composite implementing the account services.
</LI>
<LI>bigbank.accountdata<BR/>
This contains the source code and SCDL artifacts for the SCA HTTPD BigBank
composite implementing the account data services.
</LI>
<LI>bigbank.wsclient<BR/>
A sample client which uses an SCA Web Service reference to make a remote
call to the BigBank service.
</LI>
</UL>
<P>Additionally, there is the bigbank.app.composite file. This
describes the configuration of the SCA BigBank composite deployed to the SCA
runtime.
</P>
<P>Note that this sample does not run on Windows, due to threading incompatibilities
between Apache HTTPD and the Ruby runtime</P>

<OL>
<LI>The following environment variables are required:

<LI>As the HTTPD BigBank sample is based on Ruby scripts, a specific compilation step is not necessary -
only deployment is required. Deploy the Ruby samples only with the following command sequence:

<LI>./configure --enable-ruby --enable-cpp=no --prefix=$TUSCANY_SCACPP/samples</LI>
<LI>make install</LI>

<LI>Start the Apache HTTPD server:

NOTE: Depending on your installation of Apache HTTPD you may need to log in as root before following
these steps. If so, you may also need to uncomment the User and Group directives in the
<tuscany_sca_install_dir>/samples/HttpdBigBank/deploy/httpserver/conf/httpd.conf file
and set these to the appropriate username and group that the server should run as</LI>

<LI>The PHP web client detailed in the

<DIV CLASS="section">
<A NAME="win"><H2>The HTTPD BigBank sample on Windows</H2></A>
<P>The HttpdBigBank sample does not currently run on Windows, due to the sample being based on Ruby
components running under Apache HTTPD. The Ruby runtime is single-threaded and, on Windows, HTTPD
is multi-threaded, which means that Ruby throws "cross-thread violation" errors when Tuscany
attempts to run a Ruby script under HTTPD.</P>

<DIV CLASS="section">
<A NAME="help"><H2>Getting Help</H2></A>
