I am having a problem with my Primefaces Project. I am using Primefaces 5.2 and also Hibernate 5.0 for ORM. I am working on Eclipse and using Microsoft SQL Server. I am NOT using Maven (which I noticed several people do use). I also checked several SO questions with no positive result, including these:
unable to create managed bean primefaces
Unable to create managed bean UserBean - JSF
Previous to the error I was able to Write to my Database from a Java Controller without trouble and verified the correct insertion directly on my database.
I am now working on a LogIn validator, for which I have this class I am working on:
package modelo;
import java.util.List;
import java.util.Date;
import java.util.Iterator;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import modelo.Empleado;
public class LoginController {
private static SessionFactory factory;
private String usuario;
private String contraseña;
public String validar(){
try{
factory = new Configuration().configure().buildSessionFactory();
System.out.println("Validando");
}
catch (Throwable ex) {
System.err.println("Failed to create sessionFactory object." + ex);
System.out.println("NOPE");
throw new ExceptionInInitializerError(ex);
}
LoginController LC = new LoginController();
/*Verificar exista un usuario con ese login_name y contraseña*/
Session session = factory.openSession();
Transaction tx = null;
try{
tx = session.beginTransaction();
List validados = session.createQuery("FROM EMPLEADO WHERE contraseña ='"+contraseña+"' and nombre ='"+usuario+"'").list();
Empleado emp = (Empleado) validados.get(0);
if(emp == null){
System.out.println("Error de Autenticación");
return "login";
}
else{
System.out.println("Autenticacion Correcta, User: "+usuario+", pass: "+contraseña);
return "asistencia";
}
}catch(HibernateException e){
if (tx!=null) tx.rollback();
e.printStackTrace();
}finally{
session.close();
}
return "login";
}
public String getUsuario() {
return usuario;
}
public void setUsuario(String usuario) {
this.usuario = usuario;
}
public String getContraseña() {
return contraseña;
}
public void setContraseña(String contraseña) {
this.contraseña = contraseña;
}
}
However, when I run it I get the following error:
I have searched for a way to "configure" that "dependency" but with no success. I am possitive that my hibernate.cfg.xml is correctly written because I could write to my DB as mentioned above, however here is the code for that file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>

<property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=Medidas</property>

<property name="show_sql">false</property>
<property name="current_session_context_class">thread</property>
<!-- Mapping files -->
<mapping resource="Empleado.hbm.xml"/>
</session-factory>
</hibernate-configuration>
I suspect it has something to do with the web.xml file but I did not find how to configure it. Here is my web.xml practically unchanged since I downloaded the Base Project:
<?xml version="1.0" encoding="UTF-8"?>

<!-- The bare minimum needed for JSF 2.2 is a servlet 2.5 or later
declaration (this uses 3.0) and the mapping for the FacesServlet.
Setting PROJECT_STAGE to Development is highly recommended
during initial development so that you get more helpful
error messages. Whether you want server-side state saving
(default) or client-side is a more complicated question:
client-side uses more bandwidth but fewer server resources.
Client-side also helps to avoid the dreaded view expired exceptions.

Any Ideas on what is causing my problem? Should I add configurations or dependencies that I am missing? Thanks in advance (if you need more snippets or information please do tell me)
