What is the difference between pageContext and page implicit objects in JSP?
The page object represents the generated servlet instance itself, i.e., it is same as the "this" keyword for a Java file. As a result, you do not typically know who the super class is, and consequently do not normally make use of this object or its methods. The pageContext object represents the environment for the page, containing useful information like page attributes, access to the request, response and session objects, as well as the JspWriter referenced by out. This object also has methods for including another URL's contents, and for forwarding or redirecting to another URL. For example, to forward a request to another resource from in a JSP page, we can do that by using the pageContext variable: pageContext.forward ("other.jsp");
How can you move the data from servlet to jsp?
To move data from a servlet to a JSP, you can use the request object to set attributes. You can call request.setAttribute("attributeName", data) in the servlet to store the data. Then, use request.getAttribute("attributeName") in the JSP to access that data. Finally, forward the request to the JSP using a RequestDispatcher, like request.getRequestDispatcher("yourPage.jsp").forward(request, response).
