JSF Question
Submitted by jsfgeeks on Thu, 02/05/2009 - 08:57.
Hi all,
I want to create a page like Master Page in JSF application. I have header, footer, sidemenu, rightmenu, and main page in between.
Even if the content of main page is too large, the footer and other things should look perfect, without overriding eachother.
Any help regarding this will be appreciated.
Thanks in advance,

You could use tiles with JSF
You could use tiles with JSF to fulfill your requirement. here is a outline of what could be done.
1. Add tiles descriptor in your webapp : To do this ,in your web.xml specify the context init param javax.faces.application.CONFIG_FILES. Set the param value to the path of the web application configuration files.
Here is an example:
<context-param><param-name>javax.faces.CONFIG_FILES</param-name>
<param-value>/WEB-INF/faces-config.xml, /WEB-INF/tiles-defs.xml</param-value>
</context-param>
2. Also you need to add Tiles framework to your webapp by specifying the Tiles Servlet in the web.xml. Here is an example
<servlet><servlet-name>Tiles Servlet</servlet-name>
<servlet-class>
org.apache.struts.tiles.TilesServlet
</servlet-class>
<init-param>
<param-name>definitions-config</param-name>
<param-value>/WEB-INF/tiles-defs.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
3. Copy the struts-tiles.tld to the WEB-INF directory. The namespace for the tags defined in this tld is is http://jakarta.apache.org/struts/tags-tiles
4. Now create your JSPs
4.1 body.jsp : this is the jsp which will contain the body
4.2 header.jsp : this shows the header
4.3 footer.jsp : the footer you want to show
4.4 tiles.jsp : this is the wrapper over body.jsp. you need to hit this page in app. example :
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles" %>
<html>
<f:view>
<head>
</head>
<body>
<f:subview id="body">
<h:form>
<tiles:insert definition="layout" flush="false">
<tiles:put name="table" value="body.jsp"/>
</tiles:insert>
</h:form>
</f:subview>
</body>
</f:view>
</html>
4.5 layout.jsp : to layout your elements...
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles" %>
<tiles:importAttribute scope="request"/>
<h:panelGrid>
<f:subview id="header">
<tiles:insert attribute="header" flush="false"/>
</f:subview>
<f:subview id="table">
<tiles:insert attribute="table" flush="false"/>
</f:subview>
<f:subview id="footer">
<tiles:insert attribute="footer" flush="false"/>
</f:subview>
</h:panelGrid>
5. Next create tiles-defs.xml and put it in WEB-INF
Example tiles-defs.xml is :
<tiles-definitions><definition name="layout" path="/layout.jsp">
<put name="header" value="/header.jsp"/>
<put name="footer" value="/footer.jsp"/>
</definition>
</tiles-definitions>
6. you will need the following jars .
For Tiles/JSTL : standard.jar, jstl.jar,
Others : jsf-impl.jar, jsf-api.jar, struts.jar,
commons-beanutils.jar,
commons-digester.jar,
commons-collections.jar,
commons-logging.jar
