121 You are building JSP pages that have a set of menus that are visible based on a user's security role. These menus are hand-crafted by your web-design team; for example, the SalesManager role has a menu in the file /WEB-INF/html/sales-mgr-menu.html. Which JSP code snippet should be used to make this menu visible to the user? (A) ＜% if (request.isUserInRole ("SalesManager") ) { %＞＜%@ include file=' /WEB-INF/html/sales-mgr-menu.html' %＞＜% } %＞ (B) ＜jsp:if test= 'request.isUserInRole ("SalesManager") '＞＜%@ include file '/WEB-INF/html/sales-mgr-menu.html' /%＞＜/jsp:if＞ (C) ＜% if ( request.isUserInRole("SalesManager") ) { %＞＜jsp:include file='/WEB-INF/html/sales-mgr-menu.html' /＞＜% } %＞ (D) ＜jsp:if test= 'request.isUserInRole("SalesManager")'＞＜jsp:include file '/WEB-INF/html/sales-mgr-menu.html' /＞＜/jsp:if＞

122 In your web application, you need to execute a block of code whenever the session object is first created. Which design will accomplish this goal? (A) Create an HttpSessionListener class and implement the sessionInitialized method with that block of code. (B) Create an HttpSessionActivationListener class and implement the sessionCreated method with that block of code. (C) Create a Filter class, call the getSession(false) method, and if the result was null, then execute that block of code. (D) Create an HttpSessionListener class and implement the sessionCreated method with that block of code. (E) Create a Filter class, call the getSession(true) method, and if the result was NOT null, then execute that block of code.

123 A popular Ajax framework and its companion widget library contain several hundreds of files of different types (.js, .ess, .html). Your company has mandated that all its web applications use only specific versions of this framework approved by IT and repackaged internally as jar files. Furthermore, web applications should only include the entire jar, without subsetting or modification. Where should the framework's files be placed inside a jar file to enable this kind of reuse? (A) under resources (B) under META-INF/resources (C) under META-INF/web-contents (D) under WEB-INF/resources

125 A method call inside your servlet has thrown an IOException resulting from a lost network connection to a necessary resource. The servlet has determined that it will be unable to operate successfully for a few minutes, but expects to be able to resume operation after that period. How should this situation handled? (A) The servlet should re-throw the exception to the web container. (B) The servlet should throw a servletException to the web container. (C) The servlet should throw an unavailableException to the web container. (D) The servlet should redirect to an error page that reports the exception message. (E) The servlet should retry the request until the method returns successfully.

複選題127 To add a servlet to a context that has not been declared either via annotation or via the descriptor, during context initialization time the following API can be used (Choose three.)

128 In ServletContext.getNamedDispatcher(string arg0) arg0 is the (A) url of a servlet relative to the ServletRequest (B) url of a servlet relative to the Context (C) name of a servlet (D) absolute url to any servlet in any Context

129 Given a web fragment jar file, where should we put the web fragment.xml inside the jar file? (A) WEB-INF (B) META-INF (C) WEB-INF/lib (D) WEB-INF/classes (E) META-INF/services

130 What XML snippet must be added to the web.xml deployment descriptor to mandate that the container use the SSL session facility to establish a session for a client?
