Simple Tiles Controller not working!

[Barry Volpe <st...@childrencare.com>]

Trying to implement example from:

http://www.theserverside.com/resources/articles/Tiles101/article.html


Getting the following error:

************** Exception in:/tiles/penguinview.jsp] null **************



Basically trying to put a hashtable in request and tiles context cannot display in
jsp: 

public class LoadUserCategoriesController extends Action implements Controller{

public void perform(ComponentContext tilesContext,

HttpServletRequest request,

HttpServletResponse response,

ServletContext servletContext)throws ServletException, IOException{ 

Hashtable penguins = new Hashtable(20);


penguins.put("name","Name");

penguins.put("price","Price");


request.setAttribute("penguinOfTheDay", penguins); 


tilesContext.putAttribute("penguinOfTheDay", penguins);



   }
}

In tiles-def.xml

<definition name=".penguin.view" 
path="/tiles/penguinview.jsp" 
controllerClass ="com.childrencare.LoadUserCategoriesController"/>



In penguinview.jsp:

<c:out value="${penguinOfTheDay.name}"/>   




In myjsp:

<tiles:insert definition=".penguin.view" flush="true" />
 


If I remove the controllerClass in the definiton the page does not return null Exception (no error);

Looks like controllerClass is not getting called or I am not passing the correct object?

Thanks,
Barry
