Lab 3-3 — Using EL

Instructions

1. Create a servlet named Lab33Servlet and add it to the java112.project3 package.
2. In the doGet() method of the servlet, create a local variable that has the type of Map. Instantiate a new HashMap object and assign it to the variable.

3. Using the put(<K>, <V>) method add the following data to the map.

   • A number
   • A sentence of plain text
   • A fragment of HTML, like an <h2> tag text inside it
   • A new Date() object

   Map map = new HashMap();
   
   map.put("number", 1);
   map.put("text", "This is some sample text.");
   map.put("html", "<h2>This is an h2</h2>");
   map.put("aDate", new Date());
   

4. Using the setAttribute(<K>, <V>) method of the HttpServletRequest interface, add the map to the request parameter.

   request.setAttribute("myMap", map)
   

5. Forward to a JSP page named lab33.jsp.

   String url = "/lab33.jsp";
   
   RequestDispatcher  dispatcher = getServletContext().getRequestDispatcher(url);
   dispatcher.forward(request, response);
   

6. Create a JSP page named lab33.jsp and save it to your public_html directory. The page does not need use the same HTML as your index.jsp page. Just make a very simple page.

7. Add some HTML tags and EL statements to display the data in the map.

   <h2>Map on a JSP Page</h2>
   <p>${myMap["number"]}</p>
   <p>${myMap["text"]}</p>
   ${myMap["html"]}
   <p>${myMap["aDate"]}</p>
   

8. Add a link to the Lab33Servlet to your website's menu.
