我有一个耳朵和一个Ejb，该耳朵部署在AWS的ec2实例上运行的Glassfish服务器上。我也有一个要在应用程序中使用的aws RDS数据库。我有一个本地独立客户端应用程序，尝试使用jndi查找上下文从remore ejb调用函数。
所有连接均正常工作（Glassfish到db，我的机器到glassfish，我的机器到db）。
这是我的代码： Ejb实施
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));
}
}
