questa è la pagina JSP/jsf dove visualizzo il primo MockObject su combobox e poi dovrei utilizzare
Codice PHP:

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">

<f:view>
    <html>
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
            <title>Select Page</title>
        </head>
        <body>
            <h1><h:outputText value="Seleziona il Tipo di Beneficiario"/></h1>
            <h:form>
                <h:selectOneMenu id="combobox" value="#{??????}">
                    <f:selectItems value="#{SelectModel.beneficiario}" />
                </h:selectOneMenu>
                


                <h:commandButton value="Consulta" action="success" />
                <h:commandButton value="Esci" action="failure" />
            </h:form>
        </body>
    </html>
</f:view> 
ovviamente sul faces-config.xml c'è la descrizione di SelectModel
Codice PHP:
  <managed-bean>
    <managed-bean-name>SelectModel</managed-bean-name>
    <managed-bean-class>it.ex.models.MockSelectModel</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>
