For the <code>MyApplication</code> <a 21 href="resources.html">example</a>, together with a simple environment, 22 looks something like 23 this:</p> 24 <pre>from WebStack.Adapters.BaseHTTPRequestHandler import deploy # import the support for the server environment<br />from MyApplication import MyResource # import the main resource class<br />print "Serving..."<br />deploy(MyResource()) # connect a resource object to the server environment</pre> 25 <p>In the case of BaseHTTPRequestHandler, which is a module in the 26 Python standard library, you can just run this code, making sure that 27 the <code>MyApplication</code> module or package is on your <code>PYTHONPATH</code>. 28 Then, you can visit <code>http://localhost:8080</code> in your 29 browser and see the result.</p> 30 <h3>More Demanding Adapter Code</h3> 31 <p>Unfortunately, not all server environments can be connected up with 32 applications this easily. Some environments require special classes and 33 functions to be defined in the adapter code in order for 34 applications to 35 be properly integrated into those environments. A summary of the 36 requirements of each environment can be found in <a 37 href="writing-adapters.html">"Writing Adapters"</a>.</p> 38 <h2>The Deployment Process</h2> 39 <ul> 40 <li><a href="writing-adapters.html">Writing Adapters</a></li> 41 <li><a href="pythonpath.html">Getting PYTHONPATH Right</a></li> 42 <li><a href="deploying-applications.html">Deploying an Application</a></li> 43 </ul> 44 </body> 45 </html>
