Tiles-def.xml is where your applications JSPs are configured.
Tiles config comes preconfigured with some building blocks for your pages.
Pages you create should extend sapweb.standard; see oasskeleton.enter_search_criteria for an example.
You must specify a default pageAction that the page will go to. This value should match exactly an action-servlet.xml bean name.
Below are the changes made to the oas-skeleton tiles-def above for the 001s jsp, enter_001s_settings.jsp. "/UpdateSettings001s" is a bean name defined in the action-servlet.xml for settings001s project.
