[TILES] Problem using struts actions in tile's template
I'm probably being dense here (not an uncommon occurance) but I seem to be unable to
create a tile layout that uses multiple actions. I have a sample below that I'm using to
test. When I run this, I don't get any output for the header.do action call. Ultimately I would
like to have a layout that calls 4 or 5 actions but I'd like to get my test app working first :).
--------struts-config.xml-------
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd">
<struts-config>
<form-beans></form-beans>
<action-mappings>
<action path="/header"
type="com.mycompany.test.HeaderAction">
<forward name="success" path="/jsp/header.jsp"/>
</action>
<action path="/content"
type="com.mycompany.test.HeaderAction">
<forward name="success" path="/jsp/content.jsp"/>
</action>
</action-mappings>
</struts-config>
-------END struts-config.xml-----
------temptest.jsp---------------
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<tiles:insert template="/template.jsp">
<tiles:put name="title" content="Service Address" direct="true" />
<tiles:put name="header" content="/header.do" />
<tiles:put name="content" content="/content.do"/>
</tiles:insert>
------END temptest.jsp-----------
------template.jsp---------------
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<html:html>
<head><title><tiles:get name="title"/></title>
</head>
<body>
<table align="left" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr><td><tiles:get name="header" /></td></tr>
<tr><td></td></tr>
<tr><td>
<table border="0" cellspacing="0" cellpadding="0" width="100%">
<tr>
<td></td>
<td><tiles:get name="content"/></td>
</tr></table></td>
</tr>
<tr><td></td></tr>
</table>
</body>
</html:html>
------END template.jsp-----------
------header.jsp-----------------
<h3>THIS IS THE HEADER!!!!</h3>
------END header.jsp-------------
------content.jsp----------------
<B>THIS IS THE CONTENT!!</B>
------END content.jsp------------
Note:HeaderAction and ContentAction are identical except for their name. just used for testing
------ContentAction.java---------
package com.mycompany.test;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.*;
public class ContentAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
return mapping.findForward("success");
}
}
-----END ContentAction.java------
The output I get (Struts 1.1b2/Tomcat 4.1.12)
[Exception in:/header.do] Cannot forward after response has been committed
[Exception in:/content.do] Cannot forward after response has been committed
Thanks for any help/suggestions!

Ken, (long time no type)
It's hard (for me at least) to determine the problem from those spots of
code, but I have a working example that (I think) will demonstrate just what
you are trying to do.
