Objectives)
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 for each of the following
deployment descriptor elements: error-page, init-param, mime-mapping,
servlet, servlet-class, servlet-mapping, servlet-name, and
welcome-file.
Construct the correct structure for each of the following
deployment descriptor elements: error-page, init-param, mime-mapping,
servlet, servlet-class, servlet-mapping, servlet-name, and
welcome-file.
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. 6.7Given 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).
Given a scenario, write EL code that uses the following operators:
aritmetic operators, relational operators, and logical operators.
Given a scenario, write EL code that uses a function; write
code for an EL function; and configure the EL function in
a tag library descriptor.
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, and jsp:setProperty
(with all attribute combinations).
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: J2EE 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.
