The document discusses implementing the Model-View-Controller (MVC) architecture with servlets and JSP. It describes using a servlet to handle requests, call business logic to obtain result data as beans, store the beans in request/session scope, and forward the request to a JSP page. The JSP page then extracts data from the beans and displays it without modifying the beans. An example MVC implementation for a banking application that displays customer account balances in different JSP pages depending on the balance amount is also provided.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
2. • Understanding the benefits of MVC
• Using RequestDispatcher to implement MVC
• Forwarding requests from servlets to JSP pages
• Handling relative URLs
• Choosing among different display options
• Comparing data-sharing strategies
Agenda
Modèle MVC 2
4. Why Combine Servlets & JSP?
• Typical picture: use JSP to make it easier to develop and
maintain the HTML content
– For simple dynamic code, call servlet code from scripting elements
– For slightly more complex applications, use custom classes called from scripting
elements
– For moderately complex applications, use beans and custom tags
• But, that’s not enough
– For complex processing, starting with JSP is awkward ("maladroit")
– Despite the ease of separating the real code into separate classes, beans, and custom
tags, the assumption behind JSP is that a single page gives a single basic look
Modèle MVC 4
5. Modèle MVC 5
Possibilities for Handling a Single Request
• Servlet only. Works well when:
– Output is a binary type. E.g.: an image
– There is no output. E.g.: you are doing forwarding or redirection as in Search Engine
example.
– Format/layout of page is highly variable. E.g.: portal.
• JSP only. Works well when:
– Output is mostly character data. E.g.: HTML
– Format/layout mostly fixed.
• Combination (MVC architecture). Needed when:
– A single request will result in multiple substantially different looking results.
– You have a large development team with different team members doing the Web
development and the business logic.
– You perform complicated data processing, but have a relatively fixed layout.
6. Modèle MVC 6
MVC Misconceptions
❑ An elaborate framework is necessary
➢ Frameworks are often useful
❖ JSF (JavaServer Faces)
✓ You should strongly consider JSF 2.0 for medium/large projects!
❖ Struts
➢ They are not required!
❖ Implementing MVC with the builtin RequestDispatcher works very
well for most simple and even moderately complex applications
❑ MVC totally changes your system design
➢ You can use MVC for individual requests
➢ Think of it as the MVC approach, not the MVC architecture
❖ Also called the Model 2 approach
7. Modèle MVC 7
• Servlets and JSP
– Well-established standard
– Used by google.com, ebay.com, walmart.com, and thousands of other
popular sites
– Relatively low level by today’s standards
• JSF (JavaServer Faces) Version 2
– Now an official part of Java EE 6
• But runs in any recent Java-enabled server, including Tomcat 6+
– Higher-level features: integrated Ajax support, field validation, page
templating, rich third-party component libraries, etc. Designed around
the MVC approach.
– Not yet as widely used, but recommended for many or most new
projects

16. Modèle MVC 16
Implementing MVC with RequestDispatcher
1. Define beans to represent result data
– Ordinary Java classes with at least one getBlah method
2. Use a servlet to handle requests
– Servlet reads request parameters, checks for missing and malformed data, calls business
logic, etc.
3. Obtain bean instances
– The servlet invokes business logic (application-specific code) or data-access code to obtain
the results.
4. Store the bean in the request, session, or servlet context
– The servlet calls setAttribute on the request, session, or servlet context objects to store a
reference to the beans that represent the results of the request.
17. Modèle MVC 17
Implementing MVC with RequestDispatcher (Continued)
5. Forward the request to a JSP page.
– The servlet determines which JSP page is appropriate to the situation and uses
the forward method of RequestDispatcher to transfer control to that page.
6. Extract the data from the beans.
– JSP 1.2 (Old!)
• The JSP page accesses beans with jsp:useBean and a scope matching the location of step 4. The
page then uses jsp:getProperty to output the bean properties.
– JSP 2.0 (Preferred!)
• The JSP page uses ${nameFromServlet.property} to output bean properties
– Either way, JSP page does not create or modify bean; it merely extracts and
displays data that servlet created.
18. Modèle MVC 18
Request Forwarding Example
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
... // Do business logic and get data
String operation = request.getParameter("operation");
if (operation == null) {
operation = "unknown";
}
String address;
if (operation.equals("order")) {
address = "/WEB-INF/Order.jsp";
} else if (operation.equals("cancel")) {
address = "/WEB-INF/Cancel.jsp";
} else {
address = "/WEB-INF/UnknownOperation.jsp";
}
RequestDispatcher dispatcher = request.getRequestDispatcher(address);
dispatcher.forward(request, response);
20 }
19. Modèle MVC 19
jsp:useBean in MVC vs. in Standalone JSP Pages
• The JSP page should not create the objects
– The servlet, not the JSP page, should create all the data objects. So, to guarantee
that the JSP page will not create objects, you should use
<jsp:useBean ... type="package.Class" />
instead of
<jsp:useBean ... class="package.Class" />
• The JSP page should not modify the objects
– So, you should use jsp:getProperty but not jsp:setProperty.
21. Modèle MVC 21
Scopes
• Idea
– A “scope” is a place that the bean is stored. This place controls where and for how
long the bean is visible.
• Three choices
– Request
• Data stored in the request is visible to the servlet and to the page the servlet forwards to. Data
cannot be seen by other users or on other pages. Most common scope.
– Session
• Data stored in the session is visible to the servlet and to the page the servlet forwards to. Data can
be seen on other pages or later in time if it is the same user. Data cannot be seen by other users.
Moderately common.
– Application (Servlet Context)
• Data stored in the servlet context is visible to all users and all pages in the application. Rarely used.
22. Modèle MVC 22
Request-Based Data Sharing
• Servlet
SomeBean value = LookupService.findResult(...);
request.setAttribute("key", value);
RequestDispatcher dispatcher = request.getRequestDispatcher("/WEB-
INF/SomePage.jsp");
dispatcher.forward(request, response);
• JSP 2.0
${key.someProperty}
• JSP 1.2 (Old!)
<jsp:useBean id="key" type="somePackage.SomeBean" scope="request" />
<jsp:getProperty name="key" property="someProperty" />
Name chosen by the servlet.
Name of accessor method, minus the
word “get”, with next letter changed
to lower case.
23. Modèle MVC 23
Request-Based Data Sharing: Simplified Example
• Servlet
Customer myCustomer = Lookup.findCust(request.getParameter("customerID"));
request.setAttribute("customer", myCustomer);
RequestDispatcher dispatcher = request.getRequestDispatcher("/WEB-INF/SomePage.jsp");
dispatcher.forward(request, response);
• JSP 2.0
${customer.firstName}
• JSP 1.2
<jsp:useBean id="customer" type="somePackage.Customer" scope="request" />
<jsp:getProperty name="customer" property="firstName"/>
Assume that the findCust method
handles missing/malformed data.
Note: the Customer class must
have a method called “getFirstName”.
25. Modèle MVC 25
Session-Based Data Sharing: Variation
• Redirect to page instead of forwarding to it
– Use response.sendRedirect instead of RequestDispatcher.forward
• Distinctions: with sendRedirect:
– User sees JSP URL (user sees only servlet URL with RequestDispatcher.forward)
– Two round trips to client (only one with forward)
• Advantage of sendRedirect
– User can visit JSP page separately
• User can bookmark JSP page
• Disadvantages of sendRedirect
– Two round trips to server is more expensive
– Since user can visit JSP page without going through servlet first, bean data might not
be available
• So, JSP page needs code to detect this situation
27. Modèle MVC 27
Relative URLs in JSP Pages
• Issue:
– Forwarding with a request dispatcher is transparent to the client. Original URL (i.e.,
the form action URL) is only URL browser knows about.
• Why does this matter?
– What will browser do with tags like the following?
<img src="foo.gif" …/>
<link rel="stylesheet" href="my-styles.css" type="text/css">
<a href="bar.jsp">…</a>
– Browser treats addresses as relative to servlet URL
