Assignments you should complete first

Your Task: Create your own MVC Servlet based on HFSJ Chapter 3

You should accomplish this task by following these steps:

1. Do the required background reading (up through p. 71) including the reading notes for chapter 3. Then set up Tomcat on your porsche account by doing the following steps:

   1. Read over the file topics/java/basics/compliingOnPorsche.html for instructions for setting up your ECL account for compiling with Java version 5.0. Make sure that when you type "java -version" that what comes back looks like the following:

      porsche[51] > java -version                                             
      java version "1.5.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
      Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode)
      porsche[52] > 
      		  
      		  

   2. Read over the new material at the end of the file topics/tomcat/generalInstallAdvice/sharedInstall.txt for advice on how to set up your Tomcat server on one of the clients of porsche. You'll need also to consult the link on the CISC474 home page that lists the port assignments and machine assignments.

      You could test your new Tomcat server by either (i) copying the contents of the webapps directly from the $CATALINA_HOME directory, or (ii) by trying to deploy your Chapter 1 servlet, or (iii) do nothing—the next steps in this assignment involve deploying a servlet on this server, and you can wait until that step to see if your Tomcat install is working. I'll leave that choice up to you.

2. Work through the first verson of the Beer-v1 Controlller Servlet (pp. 72-81) and deploy it on your porsche-based Tomcat server. (This version contains only the "C" in "MVC").

• As you work, follow along in the reading notes from page 72 forward.

3. Work through the model class, and the second version of the Beer-v1 Controller Servlet (pp. 82-85), and deploy this on your porsche-based Tomcat server (This version is only the "MC" part of "MVC").

4. Continue with the view part (the JSP), and deploy the third version of the Beer-v1 Servlet (pp. 86-90) on your strauss-based Tomcat server (This is a full MVC version of your Beer-v1 servlet.)

• When you are finished with the final Beer-v1 servlet, make a link to it from your cisc474 web page on strauss (i.e. ~/public_html/cisc474/index.html, the one that is at the URL http://copland.udel.edu/~userid/cisc474). Label the link to this servlet clearly on the web page as "H02 Beer-v1 servlet".

5. Now repeat this process, creating an MVC servlet that is similar in functionality to the Beer-v1 servlet, but works with your product you chose for your P03 assignment instead of Beer.

   Unlike the model class on p. 82, your model class should provide advice for at least four categories. It should return at least two answers for each category, and at least three answer for one of the four categories (these are the same requirements as your table for P03).

   Note that keeping your development and deployment environments separate is a requirement of the assignment. You may be asked to show this when you demo.

   Test and deploy your servlet on porsche. For the names of the directories in the development and deployment environment, the URL, the class name and "internal secret name" (see p.46 and p.77 in HFSJ) use names modelled after those chosen for the Beer-v1 servlet, but that are appropriate to your servlet (e.g. Skis-v1 or VideoGames-v1 instead of Beer-v1

   • When it is finished, make a link to it from your cisc474 web page on strauss (i.e. ~/public_html/cisc474/index.html, the one that is at the URL http://copland.udel.edu/~userid/cisc474). Label the link as "H02 product servlet" so that it is easy to find.)

6. During lecture or office hours, demo your servlet to your instructor or TA. Your instructor/TA may ask to see your code also, and ask you to add or delete an item from your model, so be prepared to make a change, recompile, and redeploy. This might also be handled by email, so watch/listen for announcements in lecture and/or by email.
   
7. Keep your code, since you'll be using it as the basis of a future assignment. Although you won't be graded on your code in this assignment, in a future assignment you will be submitting it for a grade, so style will count.
