There are three methods to include another JSP page in one JSP page.

(1) include command The include command tells the container to copy all the content summarized by the included file and paste it into the file. <% @ Include file = "header. JSP "%> (2) include standard action <JSP: Include page =" header. JSP "/> (3) using jstl <C: Import url =" http://www.sina.com/index.html "> Note: (1) Insert" header when converting the include command. JSP Source codeThe <JSP: Include> standard action inserts the response of "header. jsp" at runtime. (2) The first two methods can only contain the current web application interface. However, "C: Import" can contain content outside the container.
