Java Jar run as Daemon cant issue exec()

I have a java socket server I wrote to allow me to keep a web clusters code base in sync. When I run the init.d script from a shell login like so

[root@web11 www]# /etc/init.d/servermngr start

Logout and all will work fine but if the server reboots or I run the init.d using services like so

[root@web11 www]# service servermngr start

Any of the exec() commands passed to the socket server will not get executed on the linux box. I am assuming it has to do with the JVM having no real shell. If I login and run

[root@web11 www]# /etc/init.d/servermngr start

...and logout all runs nice all CVS commands are executed.

Another note when run as a service the socket server responds to status checks so it is running

Here is the init.d script

#!/bin/sh
# chkconfig: 2345 95 1
# description: Starts Daemon Using ServerManager.jar.
# 
# Source function library.
. /etc/init.d/functions


start () {
    echo -n $"Starting ServerManager: "

    # start daemon
    cd /www/servermanager/
    daemon java -jar ServerManager.jar > /www/logs/ServerManager.log &
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && touch /var/lock/subsys/cups
    echo "";
    return $RETVAL
}

stop () {
    # stop daemon
    echo -n $"Stopping $prog: "
    kill `ps uax | grep -i "java -jar ServerManager.ja[r]" | head -n 1 | awk '{print $2}'`
    RETVAL=$?
    echo "";
    return $RETVAL
}

restart() {
    stop
    start
}

case $1 in
    start)
开发者_JAVA百科        start
    ;;
    stop)
        stop
    ;;
    *)

    echo $"Usage: servermngr {start|stop}"
    exit 3
esac

exit $RETVAL

And the Java responsible for actually executing the code:

// Build cmd Array of Strings
            String[] cmd = {"/bin/sh", "-c", "cd /www;cvs up -d htdocs/;cvs up -d phpinclude/"};
            final Process process;
            try {
                process = Runtime.getRuntime().exec(cmd);

                BufferedReader buf = new BufferedReader(new InputStreamReader(
                        process.getInputStream()));

                // Since this is a CVS UP we return the Response to PHP
                if(input.matches(".*(cvs up).*")){
                    String line1;
                    out.println("cvsupdate-start");
                    System.out.println("CVS Update" + input);
                    while ((line1 = buf.readLine()) != null) {
                        out.println(line1);
                        System.out.println("CVS:" + line1);
                    }
                    out.println("cvsupdate-end");
                }

            } catch (IOException ex) {
                System.out.println("IOException on Run cmd " + CommandFactory.class.getName() + " " + ex);
                Logger.getLogger(CommandFactory.class.getName()).log(Level.SEVERE, null, ex);
            }

Thx for any help

What is the command you are trying to run? cd is not a program and if you have ; you have multiple commands. You can only run one program!

---

Are you starting the process as root? What version of (bash?) is running on the system? You may want to give csh a whirl just to rule out issues with the shell itself. I'd also suggest chaining the commands with '&' instead of ';'. Finally you may find it easier to create a shell script which contains all your commands and is called by your java process. You may also want to investigate nohup and check /etc/security/limits

You might be happier using http://akuma.kohsuke.org/ to help you with this stuff, or at least Apache Commons Exec.

Here is the startup script that fixed my issue if someone runs into an issue
