JSP page implicit object


JSP page object is an instance of java.lang.Object. As we discussed earlier that JSP is translated into servlet by web container. JSP page object refers the instance of this servlet. It is act as a synonym for this object.

As it represents the servlet, it must be cast to HttpServlet.

this can also be used directly on JSP page instead of page object.

Example:

welcome.jsp

<html>
	<head>
		<title>page implicit object example</title>
	</head>
	<body> 
		<%	
		  out.print("This is a page implicit object example.");
		  out.print("Name of the auto generated servlet: " 
                                              + this.getServletName()); 
		%>
	</body>
</html>

web.xml

<web-app>
 
  <welcome-file-list>
          <welcome-file>welcome.jsp</welcome-file>
  </welcome-file-list>	
 
</web-app>
