Description copied from class: ViewBook

View a page of a book We distinguish between a textual and binary layout format. Textual formats are created by a Velocity template and are rendered to the Servlets PrintWriter. For binary formats, we first create the required assembly format (which is usually textual) by Veloctiy, then pass on the result to the presentation formatter. This will render to the Servlet's OutputStream. In both cases, callbacks into the presentation formatting systems are done by a TransformerTool.

Overrides:

action in class ViewBook

Throws:

Exception
