What is Struts? Buy It at Lowest Price on Amazon

. . . - Figure 1: The MVC architecture - . Struts

is comprised of a controller servlet, beans and other Java classes,

configuration files, and tag libraries. This means that when you have

downloaded Struts (and I'll come back to how this is done) you have

available: . a controller for your application (the Struts servlet acts as a common controller for the whole application) a collection of Java beans and other helper classes that you use in the "Model" part of your application a collection of tag libraries used in your jsp-pages To

glue these things together Struts uses a set of configuration files.

Together this gives you the skeleton that you can use to "strut" your

application. . Struts has been designed to give you modularity

and loose couplings in your application. If you're building a simple,

small application you might find it complicated to have to create and

handle so many files. You might even be tempted to put all your code in

a single jsp-file. My advice to you is: don't do it! I'm sure you can

build a single-page application faster using only one jsp-page, but if

we're talking about more complex applications, the extra effort put in

by using a modular framework will soon be rewarded. . If you hang on I'll guide you through the complete Struts application setup and hopefully show you how each piece fits in. . .
