I cannot display dynamic page title using spring 3 and apache tiles 2.2

I have a problem using spring 3 and 2.2.2 slabs. I cannot display the dynamic page title. These are my config / jsp files:

layout.jsp

<%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title><tiles:getAsString name="title" ignore="true"/></title> </head> <body> <tiles:insertAttribute name="header" /> <div id="content-outer"> <div id="content-wrapper" class="container_16"> <tiles:insertAttribute name="body" /> <tiles:insertAttribute name="menu" /> </div> </div> <tiles:insertAttribute name="footer" /> </body> </html>

Spring configuration file:

 <bean id="tilesviewResolver" class="org.springframework.web.servlet.view.tiles2.TilesViewResolver"> <property name="order" value="0" /> <property name="requestContextAttribute" value="requestContext" /> <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" /> </bean> <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer"> <property name="definitions"> <list> <value>/WEB-INF/tiles.xml</value> </list> </property> <property name="tilesProperties"> <props> <prop key="org.apache.tiles.evaluator.AttributeEvaluator">org.apache.tiles.evaluator.el.ELAttributeEvaluator </prop> </props> </property> </bean>

tiles.xml

 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN" "http://tiles.apache.org/dtds/tiles-config_2_0.dtd"> <tiles-definitions> <definition name="base.definition" template="/WEB-INF/views/layout.jsp"> <put-attribute name="title" value="" /> <put-attribute name="header" value="/WEB-INF/views/inc/header.jsp" /> <put-attribute name="menu" value="/WEB-INF/views/inc/menu.jsp" /> <put-attribute name="body" value="" /> <put-attribute name="footer" value="/WEB-INF/views/inc/footer.jsp" /> </definition> <definition name="item/itemDetail" extends="base.definition"> <put-attribute name="title" value="%{title}"/> <put-attribute name="body" value="/WEB-INF/views/item/itemDetail.jsp" /> </definition> </tiles-definitions>

the page title is not replaced by the title value displayed by the controller, instead of% {title}.

Thanks in advance

I think your page definition should look like this (note the attribute 'expression' and '$' instead of '%'):

 <definition name="item/itemDetail" extends="base.definition"> <put-attribute name="title" expression="${title}"/> <put-attribute name="body" value="/WEB-INF/views/item/itemDetail.jsp" /> </definition>

Are you sure that there is an attribute $ {title} in the corresponding area? Have you tried passing the value of $ {title} directly to the itemDetail.jsp page?

Here's the relevant documentation, tiles uses the servlet EL container support for this: http://tiles.apache.org/2.1/framework/tutorial/advanced/el-support.html .
