EJB Remote JNDI lookup не работает для сервера glassfish4, размещенного на aws ec2

/ 20 июня 2020

У меня есть Ear с Ejb, развернутым на сервере Glassfi sh, запущенном на экземпляре ec2 на aws. У меня также есть база данных aws RDS, которую я хочу использовать в своем приложении. У меня есть локальное автономное клиентское приложение, которое пытается вызвать функцию из удаленного ejb, используя контекст поиска jndi. машина в db).

Вот мой код: Реализация Ejb 

package com.example;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

/**
 * Session Bean implementation class FirstStatelessEjb
 */
@Stateless
@LocalBean
public class FirstStatelessEjb implements FirstStatelessEjbRemote {
    
    @PersistenceContext
    private EntityManager entityManager;

    /**
     * Default constructor. 
     */
    public FirstStatelessEjb() {
        // TODO Auto-generated constructor stub
    }
    
    @Override
    public void insert(String name) {
        entityManager.persist(new User(name));
    }

}

</persistence>

Главный класс в автономном клиенте 

package standaloneClient;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.example.FirstStatelessEjbRemote;

public class Main {
    
    public static void main(String[] args) throws NamingException {
        Properties jndiProps = new Properties();
        jndiProps.put("org.omg.CORBA.ORBInitialHost", "ec2-xx-xx-xxx-xxx.us-east-1e.compute-1.amazonaws.com");
//      jndiProps.put("org.omg.CORBA.ORBInitialPort","4848");

        Context context = new InitialContext(jndiProps);
        FirstStatelessEjbRemote firstEjb = (FirstStatelessEjbRemote) context.lookup("java:global/myFirtEar/myFirstEjb/FirstStatelessEjb!com.example.FirstStatelessEjb");
        firstEjb.insert("Teo");
    }

}

Имя поиска взято из журналов сервера glassfi sh.

Glassfi sh jdb c ресурсы

Экземпляр ec2 с Glassfi sh имеет открытые порты: 8080,4848,3700,3306
