JSP Directives
page directives communicate page-specific information to the JSP engine, such as buffer or thread information or specify an error page.
include directives includes an external document in the page. These are often company information files or copyright files, but can also be jsp files.
taglib directive indicates a library of custom tags that the page can include.
language directives specify script language + possible extensions. The only standard language is Java.
All are delimited by <%@ and %> markers, e.g.:
<%@ include file=“copyright.html” %>
