Hi!
I'm trying to use managed beans to request parameters from my forms. But It
doesn't work! This is the error:
| javax.servlet.ServletException: /120/SolicitarAlta.xhtml @25,60

I have created the class UserBean where you can find the atribute dni with the
get & set method:
| package com.miApp;
|
|
| import java.io.Serializable;
|
|
| public class UserBean implements Serializable
| {
| private String dni;
| private String nombre;
| private String apellidos;
| private String password;
| private String ocupacion;
| private String mail;
| private String telf;
|
| public UserBean()
| {
| }
|
| public UserBean(String dni, String nombre, String apellidos, String
ocupacion,
| String mail, String telf, String password)
| {
| this.dni = dni;
| this.nombre = nombre;
| this.apellidos = apellidos;
| this.password = password;
| this.ocupacion = ocupacion;
| this.mail = mail;
| this.telf = telf;
| this.password = password;
| }
|
| public void setDni(String dni)
| {
| this.dni = dni;
| }
|
| public String getDni()
| {
| return dni;
| }
|
| ....
|
|
Also I've added in the faces-config.xml file the managed bean:
| <managed-bean>
| <managed-bean-name>userBean</managed-bean-name>
|
<managed-bean-class>com.miApp.UserBean</managed-bean-class>
| <managed-bean-scope>request</managed-bean-scope>
| </managed-bean>
|
Does anyone know where is the error?
Thanks
