Spring & Tiles

**LilienfeldK** · Oct 14th, 2004, 08:08 AM

Hi

I'm having a bit of a weird problem with Spring and Tiles. Basically my page is divided into a header, a thinish side bar and the main area. Now my first page loads perfectly in the main area. However when I click on a link to the next page it loads only on the right hand side of the main area, as if the main area is divided exactly down the middle.

I know its a silly mistake on my side but can't figure it out as I click on a link to the first page and that loads fine!

This is the layout specified for each page: (template.jsp)

Code:

<%@ taglib prefix="tiles" uri="http&#58;//jakarta.apache.org/struts/tags-tiles" %>
<html>
	<head>
		<title>Pete's Pet Store</title>
	</head>
	<body bgcolor="lightblue">
		<table width="100%" border="0">
			<tr>
				<td colspan="2" valign="middle"><tiles&#58;insert name="topbar"/></td>
			</tr>
			<tr>
				<td width="180" valign="top">
					<tiles&#58;insert name="sidebar"/>
				</td>
				<td valign="top">
					<tiles&#58;insert name="main"/>
				</td>
			</tr>
		</table>
	</body>
</html>

This is my tiles-defs.xml:

Code:

<tiles-definitions>

	<!-- DEFAULT MAIN TEMPLATE -->
	<definition name="template" page="/WEB-INF/jsp/template.jsp">
	    <put name="topbar" value="/WEB-INF/jsp/topbar.jsp"/>
		<put name="sidebar" value="/WEB-INF/jsp/sidebar.jsp"/>
	</definition>

	<definition name="index" extends="template" path="/WEB-INF/jsp/template.jsp">
		<put name="main" value="/WEB-INF/jsp/hello.jsp"/>
	</definition>
	
	<definition name="menu" extends="template" path="/WEB-INF/jsp/template.jsp">
		<put name="main" value="/WEB-INF/jsp/menu.jsp"/>
	</definition>

</tiles-definitions>

This is the page that is causing all the problems! (menu.jsp)

Code:

<%@ include file="/WEB-INF/jsp/include.jsp" %>
<html>
<head><title><fmt&#58;message key="hello.title"/></title></head>
<body>

<h3><c&#58;out value="$&#123;model.menuname&#125;"/></h3>

<br>
<c&#58;forEach items="$&#123;model.menuitems&#125;" var="item">
<img src="image/paw.jpg" align="absmiddle"><a href="<c&#58;url value="$&#123;item.url&#125;"/>"><c&#58;out value="$&#123;item.description&#125;"/></a><br>
</c&#58;forEach>
</body>
</html>

But this is the page that is fine:

Code:

<%@ include file="/WEB-INF/jsp/include.jsp" %>
<html>
<head><title><fmt&#58;message key="hello.title"/></title></head>
<body>

<h1><fmt&#58;message key="hello.heading"/></h1>


<h3><fmt&#58;message key="hello.products"/></h3>
<c&#58;forEach items="$&#123;model.products&#125;" var="prod">
  <c&#58;out value="$&#123;prod.description&#125;"/> <i>$<c&#58;out value="$&#123;prod.price&#125;"/></i><br><br>
</c&#58;forEach>
<br>
<a href="<c&#58;url value="priceincrease.htm"/>"><fmt&#58;message key="hello.increaselink"/></a>
<br>
</body>
</html>

Please excuse my complete newbieness! Any help would be appreciated!

Thanks

Remove the path attribute from these definitions:

Code:

   <definition name="index" extends="template"> 
      <put name="main" value="/WEB-INF/jsp/hello.jsp"/> 
   </definition> 
    
   <definition name="menu" extends="template"> 
      <put name="main" value="/WEB-INF/jsp/menu.jsp"/> 
   </definition>

Hi

Thanks very much for the suggestion. I tried removing the paths but it still has the same problem. If I copy the gut of hello.jsp into menu.jsp it displays fine so I think it might be something in the actual menu.jsp code rather than the mappings. It's all very confusing to me!

Please if anyone has any more input on this topic I'd really appreciate it. I'm really stumped. :shock:

Thanks

Could you send me a sample that reproduce this issue off-line?

try adding type="page"

so you end up with

<put name="main" value="/WEB-INF/jsp/menu.jsp" type="page"/>

in your tiles definition file

I have been using Spring MVC with Tiles for a couple of projects with any issues so far.

You define two dynamic regions in your template. When you extend your template, you need provide your definition for the both regions. You don't do so. That is the reason you screw up your JSP file, I guess. You can verify it with the Tiles document.

If you know the definition of an abstract class, you might think a template as an abstract class. To instance it, you need to extend the class with all method implemented. To put a template in use, you need to provide all portions for the template.
