Problem 1
State whether each of the following is true or false. If false, explain why. a) Every JSP web page created in Java Studio Creator 2 has its own Application Bean, SessionBean, and Request Bean files. b) Event-processing life-cycle method init is invoked every time a page loads. c) Every component on a JSP web page is bound to a property in the Java page bean file. d) A single JSF component may have multiple validation components placed on it. e) If no expiration date is set for a cookie, that cookie will be destroyed at the end of the browser session. f) Each JSF component maps to exactly one corresponding XHTML element. g) Expressions in the JSF Expression Language syntax are delimited by . h) The SessionBean can store only primitive properties and properties of type String.
Problem 5
(Page Hit Counter with Cookies) Create a JSP that uses a persistent cookie (i.e., a cookie with an expiration date in the future) to keep track of how many times the client computer has visited the page. Use the setMaxAge method to cause the cookie to remain on the client's computer for one month. Display the number of page hits (i.e., the cookie's value) every time the page loads.
Problem 6
(Page Hit Counter with ApplicationBean) Create a JSP that uses the ApplicationBean to keep track of how many times a page has been visited. [Note: if you were to deploy this page on the web, it would count the number of times that any computer requested the page, unlike in the previous exercise.] Display the number of page hits (i.e., the value of an int property in the ApplicationBean ) every time the page loads.
