PageContext is a larger scope than your previous ones, and it results from working with the
findAttribute method, which on the second call finds the attribute using the name specified in the page frame, the request , session, or servlet circumstance (in that order).
What is PageContext in Servlet?
PageContext extends JspContext to provide meaningful information useful when using JSP technology in a servlet environment.
