title: Servlet JSP web.xml
body: <p>I see a feature in NetBeans for selecting a <code>JSP</code> for a <code>Servlet</code> and the result XML in <code>web.xml</code> is like this:</p>
  
  <pre><code>&lt;servlet&gt;
      &lt;servlet-name&gt;TestServlet&lt;/servlet-name&gt;
      &lt;jsp-file&gt;/index.jsp&lt;/jsp-file&gt;
  &lt;/servlet&gt;
  </code></pre>
  
  <p>What does it mean? And what is it for?
  Is it like <strong>code behind</strong> architecture in ASP .NET?</p>
