I have a console Java application, which runs all the time on a remote server (nohup java -jar myapp.jar &).

Frequently (every other day) I need to replace the JAR file by a newer one (whenever I fix a defect).

At the moment I do this by connecting to the server using ssh (WinSCP).

How can I create a mechanism, using which I could upgrade the application via the http protocol? Can I use JMX for that?

That mechanism should do following things:

a) Stop the currently running application.

b) Upload the new JAR file to the server.

c) Launch the new JAR file.

    Basically you need to break down the program into two parts:

    1. the monitor component which fetches the new jar, stops the program, replaces the jar, restarts the program

    2. the actual program, the console java application

    Theoretically you can do all of this in a single java process but the additional complexity is not worth the trouble in my opinion.
