Is it possible to use a template in a template?
I tried following:
I have a file "/templates/main.jsp", which is the main layout for all pages
(header, content and footer area and a page title):
<%-- main.jsp --%>
<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>
<html>
<head>
<title><template:get name='title'/></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<link rel="stylesheet" href=""<%=request.getContextPath()%>/css/main.css"" type="text/css">
</head>
<body>
<table>
<tr valign='top'> <tr><td><template:get name='header'/></td></tr>
<tr><td><template:get name='content'/></td></tr>
<tr><td><template:get name='footer'/></td></tr>
</table>
</body>
</html>
Second step: I don't want to say all the time what header and footer to use, so I wrote other templates (which are based on /templates/main.jsp) which grouped some header and footer scenarios together. As an example I have /templates/layout1.jsp:
<%-- layout1.jsp --%
<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>
<template:insert template='/templates/main.jsp'>
<template:put name='header' content='/header.jsp'/>
<template:put name='footer' content='/footer.jsp'/>
<template:put name='title'><template:get name='title1'/></template:put>
</template:insert>
Third step: I have a JSP page, which uses layout1.jsp:
<%-- page1.jsp --%>
<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>
index1a
<template:insert template='/templates/layout1.jsp'>
<template:put name='title1' content='Templates/Layout1' direct='true'/>
<%-- I use direct for testing only>
<template:put name='content' content="/dok1.jsp" direct='true' />
<%-- I use direct for testing only>
</template:insert>
If I call page1.jsp in the browser I get an exception (see below).
If I change the line "<template:put name='title'><template:get name='title1'/></template:put>"
in layout1.jsp to "<template:put name='title'>some static text</template:put>" everything goes right!
Can I use nested templates?
If yes, how can I use them?
