title: JSP:forward Question
body: <p>I am just getting started on web app development. I have an index.jsp that has just ONE line.</p>
  <blockquote>
  <p>&lt; jsp:forward page=&quot;landing.do?&quot;/&gt;</p>
  </blockquote>
  <p>What does</p>
  <blockquote>
  <ul>
  <li><p>the above line do?</p>
  </li>
  <li><p><strong>page=&quot;landing.do?&quot;</strong> actually refer to?</p>
  </li>
  <li><p>what does the question mark &quot;<strong>?</strong>&quot; next to <strong>&quot;landing.do?&quot;</strong> signify?</p>
  </li>
  </ul>
  </blockquote>
  <p>As Bozho rightly pointed out, a servlet called <strong>&quot;action&quot;</strong> is mapped to handle <strong>&quot;*.do&quot;</strong> in my web.xml (as shown below).</p>
  <blockquote>
  <pre><code>&lt;servlet-mapping&gt;
  
      &lt;servlet-name&gt;action&lt;/servlet-name&gt;
  
      &lt;url-pattern&gt;*.do&lt;/url-pattern&gt;
  
  &lt;/servlet-mapping&gt;
  </code></pre>
  </blockquote>
  <p>Now</p>
  <blockquote>
  <p>How do I find out what the servlet &quot;action&quot; corresponding to <strong>&quot;landing.do&quot;</strong> actually does?</p>
  </blockquote>
  <p>Thanks.</p>
