Tile Definitions - Use a Tile Definition

First import the tiles tag library with the taglib directive.
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

Second include the JSP page that defines the definition with jsp:include.
<jsp:include page="layoutDefinition.jsp"/>

Third use the tiles:insert tag, but specify the definition bean name and scope instead of the tile layout page.
<tiles:insert beanName="layoutDef" beanScope="application">
<tiles:put name="title" type="string"
value="DOG DETAIL" />
<tiles:put name="content" value="dogdetail.jsp"/>
</tiles:insert>

Fourth use the tiles:put attribute to specify title and content only.
