Chapter 11 The JSP page Directive: Structuring Generated Servlets


Listing 11.4 shows a page that uses this approach; Figures 11 7 and 11 8


show the results in Internet Explorer. Again, in a real application the data


would almost certainly be dynamically generated. For example, see Section


18.3 (Some JDBC Utilities) for some very simple methods to create an HTML


table (usable in HTML or as an Excel spreadsheet) from a database query.
