<h1>Tuscany RDB DAS Companyweb Sample</h1>
<p class=MsoNormal><u3:p> </u3:p></p>
<p class=MsoNormal>This stand-alone sample demonstrates the SDO RDB Data Access
Service in the context of a simple web application.<o:p></o:p></p>
<p class=MsoNormal><u3:p> </u3:p></p>
<p class=MsoNormal>The application starts with a database of Companies and
their related Departments.<span style='mso-spacerun:yes'>� </span>Through the
web page interface, a user can:<o:p></o:p></p>
<p class=MsoNormal><u3:p> </u3:p></p>
<ol style='margin-top:0in' start=1 type=1>
<li class=MsoNormal style='mso-list:l3 level1 lfo3;tab-stops:list .5in'>Display
all Companies in the database</li>
<li class=MsoNormal style='mso-list:l3 level1 lfo3;tab-stops:list .5in'>Display
all Companies and related Departments</li>
<li class=MsoNormal style='mso-list:l3 level1 lfo3;tab-stops:list .5in'>Add a
new Department to a Company</li>
<li class=MsoNormal style='mso-list:l3 level1 lfo3;tab-stops:list .5in'>Delete
all Departments from a Company</li>
<li class=MsoNormal style='mso-list:l3 level1 lfo3;tab-stops:list .5in'>Change
the names of Departments in a Company<o:p></o:p></li>
</ol>
<p class=MsoNormal><u3:p> </u3:p></p>
<p class=MsoNormal>So, this simple application covers all CRUD operations as
well as some relationship manipulation (adding a Department associates that
Department with the Company).<span style='mso-spacerun:yes'>� </span>The sample
runs on Tomcat 6.0 and employs a Derby database accessed via a DataSource.</p>
<h1>Running the sample</h1>
<p class=MsoNormal>There are two options for running this sample:<o:p></o:p></p>
<p class=MsoNormal><u3:p> </u3:p></p>
<ol style='margin-top:0in' start=1 type=1>
<li class=MsoNormal style='mso-list:l6 level1 lfo6;tab-stops:list .5in'>Run
from Tomcat configured by the build</li>
<li class=MsoNormal style='mso-list:l6 level1 lfo6;tab-stops:list .5in'>Deploying
the CompanyWeb WAR into a Tomcat you configure yourself</li>
</ol>
<h3>Running from Tomcat configured by the build<u3:p></u3:p></h3>
<p class=MsoNormal>You need to download the Tuscany RDB DAS source distribution
and run maven build to use this option. When you build using maven from the
source root {SRC_ROOT} directory, the sample war file is created under
{SRC_ROOT}/samples/companyweb/target. This sample application is deployed to an
instance of Tomcat as part of our automated sample testing.<span
style='mso-spacerun:yes'>� </span>For this, follow readme.htm instructions from
{SRC_ROOT}/samples/testing/tomcat. This will in-effect run the htmlunit tests
on the sample. The sample deployed on Tomcat instance will be ready this way
and you can just point your browser to <span class=MsoHyperlink><a
href="http://localhost:8080/sample-companyweb/">http://localhost:8080/sample-companyweb/</a></span>
to test further.</p>
<h3>Deploying the CompanyWeb WAR into a Tomcat you configured yourself</h3>
<p class=MsoNormal>Alternatively, you can deploy the sample to your own
configured Tomcat installation by following the instructions below.<span
style='mso-spacerun:yes'>� </span>These instructions assume that you have
either 1) downloaded the Tuscany binary distribution or 2) Downloaded the
Tuscany source and run maven build, see the following link for more details
steps on how to build DAS Sample applications <a

<h1>Sample Architecture</h1>
<p class=MsoNormal>This is a simple, single-page, web application.<span
style='mso-spacerun:yes'>� </span>The main components of this application are:</p>
<ul style='margin-top:0in' type=disc>
<li class=MsoNormal style='mso-list:l2 level1 lfo14;tab-stops:list .5in'>The
RDB Data Access Service (DAS)</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo14;tab-stops:list .5in'>SDO</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo14;tab-stops:list .5in'>CompanyClient.java</li>
<li class=MsoNormal style='mso-list:l2 level1 lfo14;tab-stops:list .5in'>Company.jsp</li>
</ul>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal><u3:p> </u3:p></p>
<p class=MsoNormal>The <b style='mso-bidi-font-weight:normal'>CompanyClient</b>
uses the <b style='mso-bidi-font-weight:normal'>DAS</b> directly and provides
high-level services to the jsp such as:</p>
<p class=MsoNormal style='margin-left:.5in'>public final List getCompanies()</p>
<p class=MsoNormal>This is a good place to look for how you might use the DAS
in your own application.<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'><u3:p> </u3:p></p>
<p class=MsoNormal>The <b style='mso-bidi-font-weight:normal'>Company.jsp</b> responds
to client interaction by invoking services of the CompanyClient.<span
style='mso-spacerun:yes'>� </span>It receives data from the CompanyClient as
SDO data graphs and manipulates SDOs directly to display data.<o:p></o:p></p>
<p class=MsoNormal><u3:p> </u3:p></p>
<p class=MsoNormal>The <b style='mso-bidi-font-weight:normal'>DAS</b> accepts
directives (commands) from the <b style='mso-bidi-font-weight:normal'>CompanyClient
</b>and reads and writes to the derby database instance appropriately.<b
style='mso-bidi-font-weight:normal'> </b><o:p></o:p></p>
