Section 1: The Servlet Technology Model

‧For each of the HTTP Methods (such as GET, POST, HEAD, and so on)
describe the purpose of the method and the technical characteristics of
the HTTP Method protocol, list triggers that might cause a Client
(usually a Web browser) to use the method; and identify the HttpServlet
method that corresponds to the HTTP Method.
‧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.

Section 2: 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.

Section 3: The Web Container Model

‧For the ServletContext initialization parameters: write servlet code
to access initialization parameters; and create the deployment
descriptor elements for declaring initialization parameters.
‧For the fundamental servlet attribute scopes (request, session,
and context): write servlet code to add, retrieve, and remove
attributes; given a usage scenario, identify the proper scope for an
attribute; and identify multi-threading issues associated with each scope.
‧Describe the Web container request processing model; write and configure
a filter; create a request or response wrapper; and given a design
problem, describe how to apply a filter or a wrapper.
‧Describe the Web container life cycle event model for requests,
sessions, and web applications;create and configure listener classes
for each scope life cycle; create and configure scope attribute listener
classes; and given a scenario, identify the proper attribute listener to use.
‧Describe the RequestDispatcher mechanism; write servlet code to create
a request dispatcher; write 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.

Section 4: Session Management

‧Write servlet code to store objects into a session object and retrieve
objects from a session object.
‧Given a scenario describe the APIs used to access the session object,
explain when the session object was created, and describe the mechanisms
used to destroy the session object, and when it was destroyed.
‧Using session listeners, write code to respond to an event when an
object is added to a session, and write code to respond to an event
when a session object migrates from one VM to another.
‧Given a scenario, describe which session management mechanism the
Web container could employ, how cookies might be used to manage
sessions, how URL rewriting might be used to manage sessions,
and write servlet code to perform URL rewriting.

Section 5: Web Application Security

‧Based on the servlet specification, compare and contrast the
following security mechanisms: (a) authentication, (b) authorization,
(c) data integrity, and (d) confidentiality.
‧In the deployment descriptor, declare a security constraint, a Web
resource, the transport guarantee, the login configuration, and a
security role.
‧Compare and contrast the authentication types (BASIC, DIGEST, FORM,
and CLIENT-CERT); describe how the type works; and given a scenario,
select an appropriate type.

Section 6: The JavaServer Pages (JSP) Technology Model

‧Identify, describe, or write the 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.
‧Write JSP code that uses the directives: (a) 'page'
(with attributes 'import', 'session', 'contentType', and
'isELIgnored'), (b) 'include', and (c) 'taglib'.
‧Write a JSP Document (XML-based document) that uses the correct syntax.
‧Describe 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.
‧Given a design goal, write JSP code using the appropriate implicit
objects: (a) request, (b) response, (c) out, (d) session, (e) config,
(f) application, (g) page, (h) pageContext, and (i) exception.
‧Configure the deployment descriptor to declare one or more tag
libraries, deactivate the evaluation language, and deactivate the
scripting language. 6.7 Given a specific design goal for including
a JSP segment in another page, write the JSP code that uses the most
appropriate inclusion mechanism (the include directive or
the jsp:include standard action).

Section 7: Building JSP Pages Using the Expression Language (EL)

‧Given a scenario, write EL code that accesses the following
implicit variables including pageScope, requestScope, sessionScope,
and applicationScope, param and paramValues, header and headerValues,
cookie, initParam and pageContext.
‧Given a scenario, write EL code that uses the following operators:
property access (the . operator), collection access (the [] operator).

Section 8: Building JSP Pages Using Standard Actions

‧Given a design goal, create a code snippet 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.
‧Given a design goal, create a code snippet using the following
standard actions: jsp:include, jsp:forward, and jsp:param.

Section 9: Building JSP Pages Using Tag Libraries

‧For a custom tag library or a library of Tag Files, create the
'taglib' directive for a JSP page.
‧Given a design goal, create the custom tag structure in a JSP page
to support that goal.
‧Given a design goal, use an appropriate JSP Standard Tag Library
(JSTL v1.1) tag from the "core" tag library.

Section 10: Building a Custom Tag Library

‧Describe the semantics of the "Classic" custom tag event model
when each event method (doStartTag, doAfterBody, and doEndTag) is
executed, and explain what the return value for each event method means;
and write a tag handler class.
‧Using the PageContext API, write tag handler code to access the JSP
implicit variables and access web application attributes.
‧Given a scenario, write tag handler code to access the parent tag and
an arbitrary tag ancestor.
‧Describe the semantics of the "Simple" custom tag event model when
the event method (doTag) is executed; write a tag handler class;
and explain the constraints on the JSP content within the tag.
‧Describe the semantics of the Tag File model; describe the web
application structure for tag files; write a tag file; and explain
the constraints on the JSP content in the body of the tag.

Section 11: Java EE Patterns

‧Given a scenario description with a list of issues, select a pattern
that would solve the issues. The list of patterns you must know are:
Intercepting Filter, Model-View-Controller, Front Controller,
Service Locator, Business Delegate, and Transfer Object.
‧Match design patterns with statements describing potential benefits
that accrue from the use of the pattern, for any of the following
patterns: Intercepting Filter, Model-View-Controller, Front Controller,
Service Locator, Business Delegate, and Transfer Object.
