tiles_and_adf: "Apache Struts, Tiles and ADF
Written By Duncan Mills, Oracle Corporation
Tiles is a technology that is widely used in conjunction with the Apache Struts Page flow controller used by the Oracle ADF framework. Tiles provides a way of defining Page fragments or 'tiles' which can be assembled into a complete page at runtime. This allows you to define the common part of your applications such as page headers and menus just once as reusable tiles, rather than repeating such common information in every page definition. Tiles is, in principle, similar to technologies such as JSP or JSTL include files."
