config refers to the configuration of the servlet. If Context refers to pageContext, then it is to manage the access to the visible part of the JSP. Both are built-in objects. Even newbie. . . . . Don't make fun of prawns

context You refer to the pagecontext object, which provides access to other JSP hidden objects. It is more common to use setAttribute () and getAttribute () methods to set and find objects. The config object is derived from ServletConfig, which contains the configuration information of the current JSP / Servlet web application.
