This lecture covers the MVC design pattern for web applications in the context of a mini-project. This includes writing servlets to control and dispatch, models to model the data and the business rules, and JSP pages to author the view.

• The controller must control and dispatch by relying on the Model and forwarding to a JSP
• Tomcat provides three Map<String,Object> places to hold data with three levels of scope: request, session, and application.
• State can be captured using the session object. Its API allows us to detect the start of new sessions.
• The model is best packaged as a Java package.
• The model uses beans and POJOs.

• Read the rest of Chapter 6.
• Do Lab 4.
