Migrating from Struts Tiles to Tiles 2

[Srikanth Jagannath]

Hi I have been looking at Tiles 2 and would like to get my application
up to this release. I have an application that uses Struts Tiles
without Struts the code in my application looks like this:

String definitionName = ???;
   // Get the definition (add appropriate catch)
 ComponentDefinition definition
= DefinitionsUtil.getDefinition(definitionName, request,
getServletContext());
   // Create new Tiles context, initialized with the definition
 ComponentContext context = new ComponentContext(
definition.getAttributes() );
   // Save context where the tiles will find it
 ComponentContext.setContext( tileContext, request);
    // Include the tiles
 String uri = definition.getPath();
 RequestDispatcher rd = getServletContext().getRequestDispatcher(uri);
 rd.include(request, response);

How can I convert this to Tiles 2 I see that some or all of the
classes above are no longer available in Tiles 2. Has someone tried to
use Tiles 2 standalone.

Thanks for your help.
