    &lt;h1>JSP 2.0 Expression Language - Implicit Objects&lt;/h1>
    &lt;hr>
    This example illustrates some of the implicit objects available
    in the Expression Language.  The following implicit objects are
    available (not all illustrated here):
    &lt;ul>
      &lt;li>pageContext - the PageContext object&lt;/li>
      &lt;li>pageScope - a Map that maps page-scoped attribute names to
          their values&lt;/li>
      &lt;li>requestScope - a Map that maps request-scoped attribute names
          to their values&lt;/li>
      &lt;li>sessionScope - a Map that maps session-scoped attribute names
          to their values&lt;/li>
      &lt;li>applicationScope - a Map that maps application-scoped attribute
          names to their values&lt;/li>
      &lt;li>param - a Map that maps parameter names to a single String
          parameter value&lt;/li>
      &lt;li>paramValues - a Map that maps parameter names to a String[] of
          all values for that parameter&lt;/li>
      &lt;li>header - a Map that maps header names to a single String
          header value&lt;/li>
      &lt;li>headerValues - a Map that maps header names to a String[] of
          all values for that header&lt;/li>
      &lt;li>initParam - a Map that maps context initialization parameter
          names to their String parameter value&lt;/li>
      &lt;li>cookie - a Map that maps cookie names to a single Cookie object.&lt;/li>
    &lt;/ul>
