Question

i have a jar file: myServerSide.jar,
this jar takes request from client apps, processes them, each one ina thread and renders a response
i’ve put my jar on linux, but i want it to be ALWAYS running

if i do java -jar myServerSide.jar & for no reason it stops after a while

i also tried deamon -- java -jar myServerSide.jar & it also stops

do you know the reason why?

what should i do,so that it stays always running, and never exit.(is it necessary to make it a service)
thanks for your help
(i’m hosting my jar on linode (a VPS) if it is related)

this is the code for my server

        try
    {

        FTLogger.getInstance().logMessage(Level.FINE, "S: Connecting...");

        ServerSocket serverSocket = new ServerSocket(SERVERPORT);
        while (true)
        {
            Socket client = serverSocket.accept();
            Thread serverThread = new Thread(new ServerThread(client));
            serverThread.start();
        }

    }
    catch (Exception e)
    {
        FTLogger.getInstance().logMessage(Level.SEVERE, "S: Error getting connection", e);
    }

in my logs, i don’t see any error, and when working the jar works as it should.
(if you’re sure that it’s smthg from my code, should i open another question, and discard this?)

Assuming you don’t have access to screen you can try nohup java -jar myServerSide.jar > log.out &
