Course Contents:

The Servlet Technology Model:

  • The HTTP Methods and corresponding HttpServlet methods
  • Using the HttpServletRequest interface, write code to retrieve HTML form parameters from the request, retrieve HTTP request header information, or retrieve cookies from the request.
  • Using the HttpServletResponse interface, write code to set an HTTP response header, set the content type of the response, acquire a text stream for the response, acquire a binary stream for the response, redirect an HTTP request to another URL, or add cookies to the response.
  • Describe the purpose and event sequence of the servlet life cycle: (1) servlet class loading, (2) servlet instantiation, (3) call the init method, (4) call the service method, and (5) call destroy method.
    • The Structure and Deployment of Web Applications:

  • Construct the file and directory structure of a Web Application that may contain (a) static content, (b) JSP pages, (c) servlet classes, (d) the deployment descriptor, (e) tag libraries, (d) JAR files, and (e) Java class files; and describe how to protect resource files from HTTP access.
  • Describe the purpose and semantics of the deployment descriptor.
  • Construct the correct structure of the deployment descriptor.
  • Explain the purpose of a WAR file and describe the contents of a WAR file, how one may be constructed.
    • The Web Container Model:

  • ServletContext initialization parameters: accessing initialization parameters; creating the deployment descriptor elements for declaring initialization parameters.
  • For the fundamental servlet attribute scopes (request, session, and context): adding, retrieving, and removing attributes; given a usage scenario, identifying the proper scope for an attribute; and identifying multi-threading issues associated with each scope.
  • The Web container request processing model; writing and configuring a filter; creating a request or response wrapper
  • The Web container life cycle event model for requests, sessions, and web applications; creating and configuring listener classes for each scope life cycle; creating and configuring scope attribute listener classes
  • The RequestDispatcher mechanism; creating a request dispatcher; writing servlet code to forward or include the target resource; and identify and describe the additional request-scoped attributes provided by the container to the target resource.
    • The JavaServer Pages (JSP) Technology Model

  • Writing JSP code for the following elements: (a) template text, (b) scripting elements (comments, directives, declarations, scriptlets, and expressions), (c) standard and custom actions, and (d) expression language elements.
  • JSP directives: (a) 'page' (with attributes 'import', 'session', 'contentType', and 'isELIgnored'), (b) 'include', and (c) 'taglib'.
  • Writing a JSP Document (XML-based document) that uses the correct syntax.
  • The purpose and event sequence of the JSP page life cycle: (1) JSP page translation, (2) JSP page compilation, (3) load class, (4) create instance, (5) call the jspInit method, (6) call the _jspService method, and (7) call the jspDestroy method.
  • JSP implicit objects: (a) request, (b) response, (c) out, (d) session, (e) config, (f) application, (g) page, (h) pageContext, and (i) exception.
  • Configuring the deployment descriptor to declare one or more tag libraries, deactivate the evaluation language, and deactivate the scripting language.
    • Building JSP Pages Using the Expression Language (EL):

  • Writing EL code that accesses the following implicit variables including pageScope, requestScope, sessionScope, and applicationScope, param and paramValues, header and headerValues, cookie, initParam and pageContext.
  • Writing EL code that uses the following operators: property access (the . operator), collection access (the [] operator).
    • Building JSP Pages Using Standard Actions and JSTL:

  • Using the following standard actions: jsp:useBean (with attributes: 'id', 'scope', 'type', and 'class'), jsp:getProperty, jsp:setProperty (with all attribute combinations), and jsp:attribute.
  • Using the following standard actions: jsp:include, jsp:forward, and jsp:param.
  • Using the appropriate JSP Standard Tag Library (JSTL v1.1) tag from the "core" tag library.
