In Service Provider, the primary layout template is defined in $WSHOME/spe/user/common/layouts/page.jsp .
<%@ taglib uri="/tags/struts-tiles" prefix="tiles" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<html:html>
<head>
<title><bean:write name="title" filter="off"/></title>
<html:base/>
</head>
<body>
<tiles:insert name="masthead"/>
<tiles:insert name="navbar"/>
<tiles:insert name="subnavbar"/>
<tiles:insert name="content"/>
</body>
</html:html>
This simple layout template indicates that the body of the page is built from four tiles: masthead, navbar, subnavbar, and content. Each tile corresponds to a JSP file in the $WSHOME/spe/user/common/tiles directory.
