Server-side Container Architecture

The AJAXTableContainerProvider is implemented as a JSPTableContainerProvider instance on the server. All the provider logic is implemented in JavaServer Page (JSP) template files of the AJAXTableContainerProvider. The container provider class remains JSPTableContainerProvider. For a content request, the AJAX Container returns a JavaScript object as a JSON representation of the display profile for the current user.

Example 5–1 JSON Representation of the Display Profile

An example JSON Representation of the Display Profile is shown here.
