rmic error class not found
问题 I'm reading head first java and I'm about to try the ready baked codes that shows how to use RMI. These are the classes: The remote interface import java.rmi.*; public interface MyRemote extends Remote { public String sayHello() throws RemoteException; } The remote implementation import java.rmi.*; import java.rmi.server.*; public class MyRemoteImpl extends UnicastRemoteObject implements MyRemote { public String sayHello() { return "Server Says,Hello"; } public MyRemoteImpl() throws

How can i build a connection between an RMI server and a RESTful web service?
问题 So I am trying to understand how to build a connection between a RMI server and a RESTful web service. My requirement is that , I need to build a web client and a RMI desktop application , which connects to a RESTful web service to conduct crud operation. I only need to use the web application to view the data in the database , but the desktop application needs to be able to conduct CRUD operations. The above provided diagram is the architecture I need to follow to develop my application. For

Alternatives to RMI
问题 I have a small Java SE application, it´s practically a fat client sitting on top of a database. To further my Java skills, I decided to make a client-server application out of it. The server application communicates with the database and handles all kinds of lengthy operations, while the client application only receives the results, mostly ArrayLists of moderate length and primitives. To this end, I started reading on RMI and did the Oracle tutorial, which I found surprisingly difficult to

CORBA： 具体的对CORBA的介绍安全客这篇文章 https://www.anquanke.com/post/id/199227 说的很详细，但是完全记住是不可能的，我觉得读完它要弄清以下几个点： 1.什么是CORBA？ CORBA全称（Common ObjectRequest Broker Architecture）也就是 公共对象请求代理体系结构 ，是OMG（对象管理组织）制定的一种标准的面向对象应用程序体系规范。其提出是为了解决不同应用程序间的通信，曾是分布式计算的主流技术。 2.CORBA能干什么？ 实现远程对象的调用 3.CORBA分为几部分？ naming service //个人感觉类似于RMI的注册表服务 client side servant side 4.CORBA的通信流程是怎样的？ 从大体上了解通信流程是怎样的，这里借用里面的图： 1.启动orbd作为naming service，会创建name service服务。 2.corba server向orbd发送请求获取name service，协商好通信格式 3.orbd返回保存的name service 4.corba server拿到name service后将具体的实现类绑定到name service上，这个时候orbd会拿到注册后的信息，这个信息就是IOR。 5.corba
