　　Section 1 - The Servlet Model
　　
　　1.1 For each of the HTTP methods, GET, POST, and PUT, identify the corresponding method in the HttpServlet class.
　　
　　1.2 For each of the HTTP methods, GET, POST, and HEAD, identify triggers that might cause a browser to use the method, and identify benefits or functionality of the method.
　　
　　1.3 For each of the following Operations, identify the interface and method name that should be used:
　　
　　Retrieve Html FORM parameters from the request
　　Retrieve a servlet initialization parameter
　　Retrieve HTTP request header inFORMation
　　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
　　1.4 Identify the interface and method to access values and resources and to set object attributes within the following three Web scopes:
　　Request
　　session
　　Context
　　1.5 Given a life-cycle method: init, service, or destroy, identify correct statements about its purpose or about how and when it is invoked.
　　
　　1.6 Use a RequestDispatcher to include or forward to a Web resource.
　　
　　Section 2 - The StrUCture and Deployment of Modern Servlet Web applications
　　
　　2.1 Identify the structure of a Web Application and Web Archive file, the name of the WebApp deployment descriptor, and the name of the Directories where you place the following:
　　
　　The WebApp deployment descriptor
　　The WebApp class files
　　Any auxiliary JAR files
　　2.2 Match the name with a description of purpose or functionality, for each of the following deployment descriptor elements:
　　Servlet instance
　　Servlet name
　　Servlet class
　　Initialization parameters
　　URL to named servlet mapping
　　
　　Section 3 - The Servlet Container Model
　　
　　3.1 Identify the uses for and the interfaces (or classes) and methods to achieve the following features:
　　
　　Servlet context init. parameters
　　Servlet context listener
　　Servlet context attribute listener
　　Session attribute listeners
　　3.2 Identify the WebApp deployment descriptor element name that declares the following features:
　　Servlet context init. parameters
　　Servlet context listener
　　Servlet context attribute listener
　　Session attribute listeners
　　3.3 Distinguish the behavior of the following in a distributable:
　　Servlet context init. parameters
　　Servlet context listener
　　Servlet context attribute listener
　　Session attribute listeners
　　
　　Section 4 - Designing and Developing Servlets to Handle Server-side Exceptions
　　
　　4.1 For each of the following cases, identify correctly constructed code for handling business logic exceptions, and match that code with correct statements about the code's behavior: Return an HTTP error using the sendError response method; Return an HTTP error using the setStatus method.
　　
　　4.2 Given a set of business logic exceptions, identify the following: The configuration that the deployment descriptor uses to handle each exception; How to use a RequestDispatcher to forward the request to an error page; Specify the handling declaratively in the deployment descriptor.
　　
　　4.3 Identify the method used for the following: Write a message to the WebApp log; Write a message and an exception to the WebApp log.
　　
　　Section 5 - Designing and Developing Servlets Using Session Management
　　
　　5.1 Identify the interface and method for each of the following:
　　
　　Retrieve a session object across multiple requests to the same or different servlets within the same WebApp
　　Store objects into a session object
　　Retrieve objects from a session object
　　Respond to the event when a particular object is added to a session
　　Respond to the event when a session is created and destroyed
　　EXPunge a session object
　　5.2 Given a scenario, state whether a session object will be invalidated.
　　
　　5.3 Given that URL-rewriting must be used for session management, identify the design requirement on session-related HTML pages.
　　
　　Section 6 - Designing and Developing Secure Web Applications
　　
　　6.1 Identify correct descriptions or statements about the security issues:
　　
　　Authentication, authorization
　　Data integrity
　　Auditing
　　Malicious code
　　Web site attacks
　　6.2 Identify the deployment descriptor element names, and their structure, that declare the following:
　　A security constraint
　　A Web resource
　　The login configuration
　　A security role
　　6.3 Given an authentication type: BASIC, DIGEST, FORM, and CLIENT-CERT, identify the correct definition of its mechanism.
　　
　　Section 7 - Designing and Developing Thread-safe Servlets
　　
　　7.1 Identify which attribute scopes are thread-safe:
　　
　　Local variables
　　Instance variables
　　Class variables
　　Request attributes
　　Session attributes
　　Context attributes
　　7.2 Identify correct statements about differences between the multi-threaded and single-threaded servlet models.
　　
　　7.3 Identify the interface used to declare that a servlet must use the single thread model.

　　8.1 Write the opening and closing tags for the following JSP tag types:
　　
　　Directive
　　Declaration
　　Scriptlet
　　ExPRession
　　8.2 Given a type of JSP tag, identify correct statements about its purpose or use.
　　
　　8.3 Given a JSP tag type, identify the equivalent xml-based tags.
　　
　　8.4 Identify the page directive attribute, and its values, that:
　　Import a Java class into the JSP page
