将命令发送到正在运行的Java进程

Question

I am making an HTTP server for a networking class that I am attending,I have made the server and now I want to be able to run the server in a terminal (say the name of the executable is myserver) and by opening another terminal I want to be able to issue commands to the already running process of the server,so instead of typing myserver to start the server ,I want to be able to type for example myserver --quit and the quit command will be send to the already running instance of the server,just like adb for android works.

So the flow of events should be something like that:

Terminal 1:

user$:myserver
server is running and listening

Terminal 2:

user$:myserver
server is already running
user$:myserver --quit
server has stopped

Whats the general idea behind that?

Answer 1

You can achieve this with Sockets. The first terminal is the Server and the second one is the client. Then you can send/receive messages and handle them in the server. Look at Oracle's example of client-server http://docs.oracle.com/javase/tutorial/networking/sockets/clientServer.html
