Hello everybody, I'm developing a very simple example application and I'm
having some trouble with it... well, first of all I'll show you some code.

- faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE faces-config PUBLIC
"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
"http://java.sun.com/dtd/web-facesconfig_1_1.dtd">



<faces-config>

present

<managed-bean-class>udg.ada.cotxes.presentacio.ConPresentacio </managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>

</faces-config>
----------------------------------

- ConPresentacio.java:

package udg.ada.cotxes.presentacio;

import java.util.Vector;
import udg.ada.cotxes.negoci.*;

public class ConPresentacio {
String dni;
String model;
String color;

public ConPresentacio()
{
dni = new String();
model = new String();
color = new String();

}

public void setdni(String dniTreb)
{

dni = dniTreb;
}

public void setModel(String m)
{

model = m;
}

public void setColor(String c)
{

color = c;
}

public Vector CConcessionari()
{
negoci n = new negoci();

return n.CercaConcessionari(dni, model, color);
}

public Vector LlConcessionari()
{
negoci n = new negoci();

return n.LlConcessionaris(dni);
}

}
----------------------------------

- There is a presentation page, it provides a link to the main site, these
presentation page only has html code, so I won't post it here. The above
mentioned main site is index.jsp (go directly to JSF section):

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%--
The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library...
action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

Your bean is missing a getter (and a correct setter) for the 'dni'
property.

Int he future, you might want to ask general JSF question in the SUN's
jsf forum [1] or on MyFaces user list, depending on what JSF implementation
you're using. This newsgroup is mostly for discussion of JSF *tooling* in
Eclipse.
