Chapter 14. Using Tiles
Up to this point, not much has been
said about how to organize and assemble the content and layout of JSP
pages for a Struts application. In many ways, that is outside the
scope of the topic of Struts. Many excellent books are available that
provide strategies for organizing web content and the layout of
pages. A good book on general Web design is Learning Web
Design, by Jennifer Niederst (O'Reilly).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.A third approach, which is introduced in this chapter, describes a
far better way to reduce the amount of
redundant code a
web application contains and, at the same time, allows you to
separate the content from the layout better than the first two
approaches. |
