The page directive is used to provide instructions to the container. These instructions pertain to the current JSP page. You may code page directives anywhere in your JSP page. By convention, page directives are coded at the top of the JSP page.
Following is the basic syntax of the page directive −
<%@ page attribute = "value" %>
You can write the XML equivalent of the above syntax as follows −
<jsp:directive.page attribute = "value" />
