Class Description

Class Overview

Class Goals

• Understand the value of web applications to an IT enterprise, and the importance of the Java EE platform in enabling web development.
• Build servlets to respond to HTTP requests.
• Build JavaServer Pages to define HTTP responses.
• Combine servlets and JSPs in a model/view/controller architecture to maximize efficiency and maintainability of application code.
• Define HTML forms and process form input.
• Store and retrieve information at request, session, and application scope.
• Make effective use of HTTP sessions as managed by the Java EE web container.
• Use the JSP Standard Tag Library to implement appropriate presentation logic in a JSP.
• Take full advantage of the relationship of servlets and JSPs to the Java EE web container using configuration, context, and lifecycle techniques.
• Manage persistent data from web applications by working with persistence tiers, JDBC, and/or JPA.
• Implement and configure servlet filters.
• Declare security policies for web applications, and use programmatic authorization where appropriate.
