Tiles use RequestDispatcher.include() to include a tile or call a controller. The original request is accessible in all the included tiles or controller. So, you can access the userId. Here is a step through of the process I envision request -> Action -> page that contains controllerUrl tile definition -> menu tile calls controllerUrl Action -> (Here is where I want to pass parameters into the request spawned by the controllerUrl) Here you retrieve the userId, and create the appropriate user menu. There is several solutions: * set a tile attribute to a predefined menu definition * create dynamically a list of menu entry * ... Action does it's magic -> Action returns a page with a menu customized to a particular user. The action forward to the menu tile which retrieve the appropriate attribute and show it as a menu ... Check the example in struts-documentation/example: there is a user customizable menu. This menu is set in a controller according to what the user has chosen. The corresponding definition is in tiles-examples-def.xml (examples.userMenu). Cedric Thanks for your help.

What you want is to be able to add a request parameter to the current requestResponse. When Tiles include the controller via its url, is simply do an include, and doesn't modify the requestResponse object. So, you still have all the http parameters that are associated to the request. You can yourself modify the requestResponse object in your action before inserting the tiles. Check the jsp and servlet spec to know if it is possible to add an http parameter. Personally I use to pass such extra parameters in the request context or Tile context rather than a new http parameter.
