JSP info Attribute





info Attribute


As we know that every JSP web page is automatically translated to its equivalent Servlet. In JSP, the info attribute allows us to set a String message about the current JSP page, this message could be retrieved and read using the translated Servlet's getServletInfo() method.



Syntax of info Attribute


<%@ page info = "A message" %>





info Attribute Example


In the upcoming example, we are setting info attribute of page directive with a message, this message will be displayed by calling getServletInfo() method of the Servlet(translated from this JSP).

Info.jsp
<html>

<head>

<title>
JSP info attribute
</title>

</head>


<body>

<%@ page  info ="Decodejava.com is an online portal An online portal that provides 
easy tutorials of Java programming language." %>

<h2>Information about JSP page</h2>

<%= getServletInfo() %> <br/>

</body>

</html>



executing this JSP page gives us an information set by the info attribute by using getServletInfo() method of javax.servlet.Servlet class.

Note :


You could place page directive containing info attribute or any of its attributes, inside/outside the tag of html or even at the beginning of the JSP file and result will still be the same. For example - let's see what happens when we place the page directive containing the info attribute at the beginning of the JSP file.

Info2.jsp
<%@ page  info ="Decodejava.com is an online portal An online portal that provides 
easy tutorials of Java programming language." %>

<html>

<head>

<title>
JSP info attribute
</title>

</head>


<body>

<h2>Information about JSP page</h2>

<%= getServletInfo() %> <br/>

</body>

</html>


We leave the result for you to find out.
