first JSF page...

With the following files:

test.jsp
--------
 
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> 
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> 
<html> 
<body> 
<f:view> 
 
<h:outputText value="First JSF Page !!!"/>

</f:view> 
</body> 
</html>

web.xml
-------
 
<?xml version="1.0" encoding="UTF-8"?> 
 
<web-app version="2.4" 
         xmlns="http://java.sun.com/xml/ns/j2ee"

faces-config.xml
----------------
 
<?xml version="1.0"?> 
<!DOCTYPE faces-config PUBLIC 
  "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN" 
  "http://java.sun.com/dtd/web-facesconfig_1_0.dtd"> 
 
<faces-config> 
 
</faces-config>

Now, here, we can't directly access JSP page(http://localhost:8081/JSFLogin/pages/test.jsp), if we do that then an exception is thrown. Because FacesServlet should be initialized (called) before we access any tag of JSF. So for accessing this JSP page we will have to go through the FacesServlet...

So as per mapping in web.xml, we will access it with faces extension (http://localhost:8081/JSFLogin/pages/test.faces), it will call FacesServlet and that will display our test.jsp.

Now, my confusion is, why we need faces-config.xml in this example??? (we are not providing any navigation rule, managed bean etc).

Please guide...

And also, all my assumptions are right or not??

Thanks a lot.

I think, I understood it.

Actually, whether we are using faces-config.xml in this example or not, FacesServlet class try to find this file, loads the content of this file into some object, initialize any bean if present etc. So if we don't provide faces-config.xml the FacesServlet doesn't let us to go ahead...
