Component Views and Tiles

["Lafredo, Stephen" <st...@merck.com>]

Hi,

I am using Apache 1.3.20, Tomcat 4.0.4 and Struts 1.1-rc1.

I am attempting to port my existing JSP component view framework into Tiles.

I have succeeded so far but I am having trouble including in an include. For
example,

This is my tiles-def.xml

<tiles-definitions>
  <definition name="hlf"
              path="/WEB-INF/jsp/templates/hlf.jsp">
    <!-- head content -->
    <put name="meta-tags"       value="/WEB-INF/jsp/common/meta-tags.jsp" />
    <put name="page-directives"
value="/WEB-INF/jsp/common/page-directives.jsp" />
    <put name="head"
value="/WEB-INF/jsp/templates/portal/head.jsp" />

    <!-- body content -->
    <put name="header"  value="/WEB-INF/jsp/templates/portal/header.jsp" />
    <put name="footer"  value="/WEB-INF/jsp/templates/portal/footer.jsp" />
  </definition>

  <!-- sample report page -->
  <definition name="report"
           extends="hlf">
    <put name="subTitle" value="report.do action response" />
    <put name="layout"   value="/WEB-INF/jsp/templates/layout/plain.jsp" />
    <put name="content"  value="/WEB-INF/jsp/report/content.jsp" />
  </definition>

</tiles-definitions>

This is a portion of my primary template.

 </td></tr><tr><td>
   <%-- include the page layout --%>
   <tiles:insert attribute="layout" />
 </td></tr><tr><td>

This is the contents of plain.jsp

<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<%-- default page content, use it for displaying a one module --%>
<table summary="content" border="0" cellpadding="0" cellspacing="15"
width="100%">
  <tr><td>
  <hr color="#6fa399" />
  </td></tr>
  <tr><td width="100%" valign="top">
    <%-- include page content --%>
    <tiles:insert attribute="content" />
  </td></tr>
  <tr><td>
  <hr color="#d1d1d1" />
  </td></tr>
</table>

This all works pretty well. The report page is returned but the
<tiles:insert attribute="layout" /> line errors saying "content" is not
defined.

How do I either...

 1) pass the value of content to the plain.jsp by defining it w/in my
tiles-defs.xml file w/o using request parameters?

 2) define a new tile, (in my tiles-defs.xml?) and include it by definning
it w/in my tiles-defs.xml?

Thank you.
