Question

Suppose I have a java program, myProgram.jar, which I have running on a server. To start the program I would type this into the terminal:

>java -jar myProgram.jar

and the program would continue to run indefinitely. Now what about if the program had a function such as

void processInput(String text){
     //process the text
}

and I wanted to SSH into the server and call this function with a particular string? so I could log into my server at any time and alter the state of my program. Is this possible?

Answer 1

This can be done, but not easily.

There are standard ways to achieve what you probably want: MBeans. Take a look at http://docs.oracle.com/javase/tutorial/jmx/mbeans/standard.html
