I've read a LOT of documentation on the MVC model and how it is implemented in JSF, but I would like to see a small sample web app that uses JSF and the MVC arcitecture so that I can poke around the code and get a good sense of it.

Please list any places I can find such samples.

Hi mmarksbury,

> but I would like to see a small sample web app that uses JSF and the MVC arcitecture so that I can poke around the code and get a good sense of it.

JSF "is" an MVC framework, so I am not very clear by what you mean that you would like to see an app that uses JSF and the MVC arcitecture.  Have a look at the discussion here http://forum.java.sun.com/thread.jspa?threadID=563379&messageID=2782685 and there are a few tutorials about using JSF as MVC framework (if I understand you correctly):

Well, you can easily use JSF without following an MVC architecture.  For example, I could put all business logic and data access in my backing bean, or even on my JSP.  I would like to some sample code of JSF as MVC in action that follows some standards.

In short, I'm looking for a good model.

Hi mmarksbury,

yes you are right, have a look at the first link from javaworld, the JSP Model 2 is a very good example of MVC.

Hi

These are the best links:

First link provides all MVC 2 pattern support JSF implementation for Classifields.

http://publib.boulder.ibm.com/infocenter/dmndhelp/v6rxmx/index.jsp?topic=/com.ibm.etools.webtools.tutorial.doc/topics/intro.html

Second one  will provide IDE and some tutorials to create jsf applications

http://www.exadel.com

Hope this will help you to build good JSF knowledge :)

I still haven't seen a good model of a JSF built on the MVC architecture.  I am looking for a sample application, nothing big, but a working sample that I can look at and learn from.  I know JSF already, and I understand the MVC model.  I simply want to poke around at an application that has already been built.  Anyone have a link to such a sample application?

>I still haven't seen a good model of a JSF built on the MVC architecture.
I am not an JSF expert.  But, for the sake of this dicussion,  I propose a simple app.  
 the model
----------------------------------------------------------------
package myPack;
public class UserBean{
                 private int count;
                 public UserBean(){
                                   count = 0;
                 }
                 public int getCount(){
                           return count;
                 }
                 public void addOne(){ count++;}
}
-----------------------------------------------------------------------------------
the view  
-------------------------------------------------------------
    <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
    <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<HTML>
    <HEAD> <title>MVC</title> </HEAD>
    <body>
      <f:view>
           <h:form id="AddOneForm" >
                 <h:outputText id="count" value="#{userBean.count}"/>  
                 <h:commandButton id="addOne" value="addOne" action="#{userBean.addOne}"/><p>
           </h:form>
      </f:view>
    </body>
</HTML>
---------------------------------------------------
in  faces-config.xml
-----------------------------------------
<faces-config>
  <managed-bean>
    <managed-bean-name>userBean</managed-bean-name>
    <managed-bean-class>myPack.UserBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>
</faces-config>

It seems to me that there is a lot of descrepancy out there as to what in JSF is the Model and what is the View/Controller...hence, the reason for my question in the first place.

In many tutorials and even in answers within this question, I see reference to backing beans as the model.  It seems to me that it would play out more like this.  What do you all think?

Model:
----------------
Class library or classes containing business objects that reflect your business process needs including classes and methods that handle data access.

View:
----------------
The JSF's and UI components that actually present data on the page.

Controller:
----------------
A combination of various things including Backing Beans that control the flow of the application.  For example, a faces servlet in combination with a backing bean sending a response.

yes it  seems like that

but

JSF is like a swing application from server side :)
