RE: how to use controllerclasses with tiles?

[Fahd Ahmed]

ok i'll try to explain.

below is the part of my definitions-config file where i declare the
controller class

    <definition name="header" path="/common/header.jsp" controllerClass
="com.sam.tilescontroller.TestTileController" >
        <putList name="globalNavigation">
            <item value="Home" link="/prototype" />
        </putList>
    </definition>


my controller class is as follows

package com.sam.tilescontroller;

import java.util.*;
import java.lang.*;

import javax.servlet.ServletContext;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.tiles.Controller;
import org.apache.struts.tiles.ComponentContext;
import org.apache.struts.tiles.actions.TilesAction;


class TestTileController extends TilesAction implements Controller
{

        public void perform( ComponentContext context,
                                HttpServletRequest request,
                                HttpServletResponse response,
                                ServletContext servletContext)
        {
                try{
                        context.putAttribute("title", "hello from controller");
                }catch(Exception ex)
                {
                        System.out.println("Exception in TilesController---" + ex);
                }
        }
}


now just this code generates the error no matter i use the value stored in
context in my header.jsp or not. but for completion the header.jsp look like

<jsp:root
        xmlns:jsp="http://java.sun.com/JSP/Page";
        xmlns:c="http://java.sun.com/jsp/jstl/core";
        xmlns:tiles="http://jakarta.apache.org/struts/tags-tiles";
        xmlns:fn="http://java.sun.com/jsp/jstl/functions";
        version="2.0" >

    <tiles:importAttribute name="title" scope="page" />

    <c:url value="/images/safe-logo4.png" var="logoURL"/>
    <table width="100%">
        <tr>
            <td width="20%" align="left"><img src="${logoURL}" /></td>
            <td width="60%" align="center"><font
size="4"><b>${title}</b></font></td>
                <td width="20%"> </td>
        </tr>
        <tr>
            <td colspan="3" align="center">
                <c:if test="${not empty globalNavigation}">
                    <c:forEach items="${globalNavigation}" var="item">
                        <c:url var="link" value="${item.link}" />
                        | <a href="${link}">${item.value}</a>
                    </c:forEach>
                    |
                </c:if>
    <jsp:scriptlet>
        System.out.println("ident = " + request.getParameter("title"));
    </jsp:scriptlet>
            </td>
        </tr>
    </table>
</jsp:root>


also the web.xml has the following entry

   <servlet>
      <servlet-name>Tiles Servlet</servlet-name>
      <servlet-class>org.apache.struts.tiles.TilesServlet</servlet-class>
      <init-param>
         <param-name>definitions-config</param-name>

<param-value>/WEB-INF/safe-tiles.xml,/WEB-INF/situation-tiles.xml</param-val
ue>
      </init-param>
      <load-on-startup>2</load-on-startup>
   </servlet>

guess now you may be able to understand and pin point the problem.'

Fahd,

I've successfully implemented heaps of controller classes, but I'm
having trouble visualising what you have done.

Any chance of a code example?
