Introduction to JSPSingleContainerProvider

A single container wraps the content of a single channel. The single container enables a channel to take over an entire browser page. For example, this can be used to provide the front page or can be used to display a single channel whose name is passed in the request parameter. Typically, the front page consists of some banners and the output of another channel. The purpose of the single channel is to allow these banners, menu bars, and the like to be wrapped around the content of the included channel.

Another purpose of the single container is that the decorational elements (such as banners and menu bars) which wrap around the channel can be easily changed without changing the channel itself.
