Crear Helper EditPersonHelper.java Crear Package : com.aplicacion.presentacion.helper package com.aplicacion.presentacion.helper; import com.aplicacion.presentacion.model.Person; /** * Implement Services needed to edit and save * a Person object's state. In this implementation * the Person object's state is stored in memory * @author brucephillips * */ public class EditPersonHelper { private static Person person ; private static String [] carModels = {"Ford","Nissan"};

EditPersonHelper.java static { person = new Person(); person.setFirstName("Bruce"); person.setLastName("Phillips"); person.setSport("basketball"); person.setGender("not sure"); person.setResidency("KS"); person.setOver21( true); person.setCarModels( carModels); } public Person getPerson() {

Person.java Crear Package com.aplicacion.presentacion.model package com.aplicacion.presentacion.model; import java.util.Arrays; public class Person { private String firstName; private String lastName; private String sport; private String gender; private String residency; private boolean over21; private String [] carModels;

Person.java public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; }

State.java package com.aplicacion.presentacion.model; public class State { private String stateAbbr; private String stateName; public State (String stateAbbr, String stateName) { this.stateAbbr = stateAbbr; this.stateName = stateName; } public void setStateAbbr(String stateAbbr) { this.stateAbbr = stateAbbr; } public String getStateAbbr() { return stateAbbr; } public void setStateName(String stateName) { this.stateName = stateName; } public String getStateName() { return stateName; } public String toString() { return getStateAbbr() ; } }

Crear EditAction.java package com.aplicacion.presentacion.action; import com.opensymphony.xwork2.ActionSupport; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import com.aplicacion.presentacion.model.Person; import com.aplicacion.presentacion.model.State; import com.aplicacion.presentacion.helper.*; import com.opensymphony.xwork2.ActionSupport;

public class EditAction extends ActionSupport { private static final long serialVersionUID = 1L; private EditPersonHelper editService = new EditPersonHelper(); private Person personBean; private String [] sports = {"football", "baseball", "basketball" }; private String [] genders = {"male", "female", "not sure" }; private List<State> states ; private String [] carModelsAvailable = {"Ford","Chrysler","Toyota","Nissan"}; public String execute() throws Exception { editService.savePerson( getPersonBean() ); return SUCCESS; }

Crear edit.xml para registrar Action <?xml version= "1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN” "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name= "struts.devMode" value="false" /> <package name= "editar" extends="struts-default" namespace="/ingreso">   <action name= "index"> <result>/index.jsp</result> </action> <action name= "edit" class="com.aplicacion.presentacion.action.EditAction" method="input"> <result name= "input">/ ingreso/formulario.jsp</result> </action> <action name= "save" class="com.aplicacion.presentacion.action.EditAction" method="execute"> <result name= "success">/ ingreso/resultado.jsp</result> </action> </package> </struts>

Registrarlo en Struts.xml <include file= "edit.xml"/>
