Answer / guest
The implicit variable page is of class java.lang.Object and
it refers to instance of generated servlet. It is declared as
Object page=this
Consider
<%= page.getServletInfo() %> will give Error
getServletInfo() is not a method of java.lang.Object
<%= ((Servlet)page).getServletInfo() %> is valid
pageContext variable is of type
javax.servlet.jsp.PageContext. The PageContext class is the
abstract class and JSP engine vendor provides its concrete
subclass.
·Store reference to implicit objects,
·Provide method to get and set attributes in different scopes.
·Provide convenience methods for transferring request to
other resources in web application.
PageContext.forward(“other.jsp”);
