Can anyone tell me the relationship of Struts framework and Front Controller design pattern of J2EE?

[Liang Li <Ll...@Cleanwise.com>]

Hi,
 
I find the url
http://java.sun.com/j2ee/blueprints/design_patterns/front_controller/index.h
tml
<http://java.sun.com/j2ee/blueprints/design_patterns/front_controller/index.
html>  describing the front controller design pattern. I think it has
relationship with the Struts Framework, but I'm not sure what's the
relationship.
 
Can anyone tell me the relationship between them? And what's the advantage
of struts?
 
Thanks in advance.

The Struts framework implements the Front Controller pattern as its
ActionServlet.

Using that vocabulary, the ActionMappings are the Dispatcher. 

The advantage of Struts is that the Front Controller, Dispatcher, and
several other J2EE patterns have already been implemented for you, and
are ready to use!

Our friend Dan Malks, et al, have developed the architectural patterns
based on real-life implementations, including, I imagine, what we have
been doing with Struts. 

My copy of "Core J2EE Patterns" just came yesterday, and I'm looking
forward to reading it in-depth.
