Developing Java Web Applications

Gives the experienced Java programmer a firm understanding of web application development in the Java Enterprise environment. Students learn the Servlets, JSP, and JSTL standards and how to mesh them into an effective methodology for building maintainable model/view/controller web applications. Students also work with relational databases and are exposed to practicalities of using both JDBC- and JPA-based persistence tiers. The course also introduces security concepts and provides exercises in both declarative and programmatic approaches to authentication and authorization for Java web applications.

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.
