In the Storefront application, we have used two different approaches to assembling web pages. The first approach, sometimes referred to as a straight JSP-based approach, is probably the most familiar to web designers. The JSP pages contain presentation logic along with HTML layout tags; there’s no separation of the two. This approach is typically used for smaller, less complicated web applications.

The second approach uses the JSP include directive. It’s used by developers for larger web applications, or after they realize how repetitive the first approach can be. If you have spent much time maintaining web applications, you know how frustrating it can be to update a site’s look and feel. Using the JSP include directive allows for more reuse, which reduces the total development and maintenance costs.
