Step 2: Sample code of master page.
<%@taglib uri="http://www.opensymphony.com/sitemesh/decorator" prefix="decorator"%>
<%@taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@taglib uri="http://java.sun.com/jstl/fmt" prefix="fn" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><decorator:title/></title>
</head>
<body>
<decorator:body/>
</body>
</html>
Step 3: Configure the sitemesh to pass request of the page through the template/master page. Create decorators.xml file in WEB-INF folder as follow.
<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/template">
<decorator name="main" page="template1.jsp">
<pattern>/Folder_name/*</pattern>
<pattern>/Folder_name2/test.jsp</pattern>
</decorator>
</decorators>
- - defaultdir : Path of template/master page
- - page : Template/master page that will be applied to pages
- - /Folder_name/* : The URL pattern (Directory) on which the template/master page will be applied.if we use /* so all request pages pass through the template and it'll be applied to all page.
- - /Folder_name2/test.jsp : Template/master page will render only test.jsp file of Folder_name2 directory. Other file will be displayed as normal page.
Step 4: Configure the web.xml file. Append the below code in web.xml file.
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- - /* : Template applied to all page extension.
- - /.html : Template applied to only on html page.
