  3. Assignment Guideline 1

  4. Assignment Guideline 2 • Using methods • Remote Host: request.getRemoteHost() • Remote Port: request.getRemotePort() • Request URI: request.getRequestURI() • Server name: request.getServerName() • Server port: request.getServerPort() 4

  5. Assignment Guideline 3 – 1 • Building 2 servlets • InputServlet includes the form and inputted controls • DisplayServlet presents the inputted value 5

  6. Assignment Guideline 3 – 2 • 301 (Moved Permanently) • Requested document permanently moved elsewhere (indicated in Location header). • Browsers go to new location automatically • Hints: • Using setStatus and setHeader as following • response.setStatus(301); • response.setHeader( "Location", "http://localhost:8084/AssM3/MovePermanently.html" ); • response.setHeader(“Connection”, “close”); • Using sendError with the same status code 6

  7. Assignment Guideline 4 – 1 • Building 2 servlets • CookiesServlet includes the form and inputted controls depending on the checking cookies result • WelcomeServlet checking the user in cookies to show welcome message and add the cookie if the new user is 7

  8. Assignment Guideline 4 – 2 • Building a servlet • Session Tracking applies the HttpSession interface methods and Session technologies to view above GUI 8

  9. Assignment Guideline 5 • Building html file same as the left above image • Building 2 servlet • First Servlet • Using the getParameter method of request object • Then using the setAttribute and getRequestDispatch methods of ServletContext Interface to store the parameter and forward the Second Servlet • Second Servlet: retrieve the object using the getAttribute method, then print it 9

  10. Assignment Guideline 6_1 • Building a servlet uses the “Basic” header and Base64Decoder to checking username and password from users • The results should be presented as above images 10

  17. Assignment Guideline 9_1 • Creating a JavaBean named AmountBean include the amount property with int data-type and the DISCOUNT is 30% • Creating includeForward.jsp file are the form with textbox and button, and applying the AmountBean to calculate the returned amount after the user submit • Creating the products.jsp file using jsp:include applying the includeForward.jsp file • Creating the forward.jsp file using jsp:forward applying the products.jsp file. The forward.jsp file is the default page of application 17

  18. Assignment Guideline 9_2 • Creating first.jsp file using request.setAttribute with value of “user” attribute is “Aptechie” and using jsp:forward to the second.jsp file • The second.jsp file uses jsp:include the lastPage.html file and present the value of “user” attribute to the browser • The lastPage.html presents the message This is the last page of this WebSite • The results of program should be same as the image 18

  19. Assignment Guideline 10_1 • Creating the JSP page using • The Arithmetic Operations • The Logic Operations • The header – EL Implicit Object with the “User-Agent” value • The Result must be same as the image 19

  20. Assignment Guideline 10_2 • Creating the JSP page using • The param – EL Implicit Object to process the inputted value • Applying the addition series calculation for Total Amount • The Result must be same as the image 20

  21. Assignment Guideline 11_1 • Creating the JSP page using • Declaring the String array with form of each elements as productName:price • Using c:forEach, c:forTokens, and c:out to traverse and print each element of array as above image 21

  22. Assignment Guideline 11_2 • Creating the JSP page using • Declaring the String array with form of each elements as destinationName:price • Building the form with a textbox and a button • Using c:forEach, c:forTokens, c:if, c:set, and c:out to traverse, checking the existing destination and print as above image 22

  23. Assignment Guideline 12_1 • Creating the I18N in Servlets as the above image using Servlets • Should reference the steps in Workshop. However, convert the reference code to the servlet 23

  24. Assignment Guideline 12_2 • Creating the JSP page using • I18N and formatting Tag library to do the exercise (using format setLocale, formatNumer and Decision making tag library to present the result) 24

  25. Assignment Guideline 13 • Do it again the workshop 3 of Chapter 13 in CD with construct if Cond Then Else 25

  26. Assignment Guideline 14 • Do it again the workshop 2 of Chapter 13 in CD that creating the custom Tag with upper case all the body content using BodyTagSupport Class 26
