Crear LoginAction en src\main\java\org\action:

package org.action;

import java.util.Map;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.ResultPath;
import org.apache.struts2.dispatcher.SessionMap;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionSupport;

@Namespace("/User")
@ResultPath(value="/")
@ParentPackage("json-default")
public class WelcomeUserAction extends ActionSupport implements SessionAware{
 private static final long serialVersionUID = 1L;

 private SessionMap<String,Object> sessionMap;
 
 @Override
 public void setSession(Map<String, Object> map) {
  sessionMap=(SessionMap)map;
 }
 
 private String userName;
 private String password;
 private String loginValido;
 
 @Action(
  value="Login", 
  results={
   @Result(
    name="success",
    type="json"
   )
  }
 )
 public String execute(){
  System.out.println("U="+this.userName);
  System.out.println("P="+this.password);
  
  if(
   this.userName.equalsIgnoreCase("cespower")
   &&
   this.password.equalsIgnoreCase("1234")
  ){
   this.loginValido="OK";
   this.sessionMap.put("userName", this.userName);
  }else
   this.loginValido="ERROR";
  
  return SUCCESS;
 }
 public String getUserName() {
  return userName;
 }
 public void setUserName(String userName) {

 }
 public String getPassword() {
  return password;
 }
 public void setPassword(String password) {
