Tiles without struts
I have a large existing application that uses a common page layout and would
like to use struts tiles. I do not want to use struts actions and such
because there is already a controller in the application, we would like to
just use the Tiles template mechanism.
>From what I've read it seems that we should be able to have the current
forwards, which are mapped in web.xml using url-mappings. The current pages
were mapped using the extension view. I am using the latest struts binary
build and tomcat 4.0. Documentation alludes that you can map urls onto
tiles-defs with the latest release. At the bottom is the request url I
tried and there was no output given in the console, just and error in the
browser "The specified HTTP method is not allowed for the requested resource
(HTTP method GET is not supported by this URL)." Hopefully someone with
more experience in Tiles could point me in the right direction; all I want
is to move our current "view" url mappings from web.xml into
tiles-definitions.xml and have tiles assemble the pages using a standard
presentation layout. Thank you for any help you provide.

Re: Tiles without struts
Posted by Cedric Dumoulin <ce...@apache.org>.
Hi,
You can use Tiles without Struts. If you want also the definition
capability, you need to initialize the Tiles factory. This can be done
by using the TilesServlet (as you do). In this case, Tiles factory
config is specified in web.xml. You don't need the TilesPlugin because
you don't use Struts.
Tiles don't support direct forward to a definition name. Definition
names are logical names. You need to map URLs to definition names. This
can be done in the servlet associated to the mapping mechanism. Map an
extension to your servlet, and in the process() method of the servlet,
do the following:
// Catch the definition name
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);
Check the TilesRequestProcessor class to know how it is done with Struts.
If you have an interesting "forward" method that can be added to
TilesServlet and you agree to share it, let us know ...
Hope this help,
Cedric
