Using the JSP useBean Tag

This free, multimedia tutorial shows you how to use IBM's Rational Application Developer (IRAD) 6.0 to create a JSP page that utilizes the jsp:useBean and jsp:getProperty tags. These tags are used to pull a JavaBean out of the HttpSession, and display the state of the JavaBean on the Java Server Page for the user.
