To Use a JSP Page Directive

1. Click the Save button. Enter line 60 as shown in Figure 12-70.

As discussed earlier, all JSPs have access to an implicit session object by
default. If you do not want a JSP page to be able to access a session object, use
the JSP page directive with the session attribute, as in
<%@ page session=”false” %>

Your pages will run faster and use less memory in the JVM; however, if you try
to access the session object, you will receive a fatal error from the JSP container.
