title: Simple Protocol Concept in Java for this setup
body: <p>i need some idea/suggestion regarding the implementation of any simple/easy to use setup for such system:  </p>
  
  <p><img src="https://i.stack.imgur.com/p6d2B.png" alt="enter image description here"></p>
  
  <p>I have two machines, where one will send commands (can be commands, configuration files, text, xml etc) (I have to decide in which way the commands should work) and the other will implement those command. However this is not a completely interactive terminal application, the sender just need to know if it was executed fine or not.  </p>
  
  <p>Also RPC is not an option, do i simply go by implementing client/server socket concept??<br>
  Is there any well known library to help realize such scenraio in Java? or may be some web server and http based communication??  </p>
  
  <p>Any suggestions for opensource libraries to realize such scenario?  </p>
