java.io.IOException：无法运行程序“ sudo sh /etc/rc.d/init.d/jbossas7 restart”：error = 2，没有这样的文件或目录

Question

I want to make my app restart JBoss which is using as a Linux service. This is how I do:

String array[] = { "sudo sh /etc/rc.d/init.d/jbossas7 restart", "login" };
String pas = "pass";
Process proc = null;
BufferedWriter writer = null;
try {
    proc = Runtime.getRuntime().exec(array);
    writer =
            new BufferedWriter(new OutputStreamWriter(proc.getOutputStream()));
    writer.write(pas);
} catch (IOException e) {
    e.printStackTrace();
}

The jbossas7 contents:

#!/bin/bash### BEGIN INIT INFO  
#chkconfig: 345 90 10

    restart)

        *)  
            echo "Usage: /etc/init.d/jbossas7 {start|stop|restart}"; exit 1;  
        ;;  
    esac  

    exit 0  

The command:

sudo sh /etc/rc.d/init.d/jbossas7 restart

works well currently in terminal mode. But my code says

java.io.IOException: Cannot run program "sudo sh /etc/rc.d/init.d/jbossas7 restart": error=2, No such file or directory

What's wrong?

Answer 1

The first element of the input array is being interpreted as the executable. Try

String array[] = 
        { "sudo", "sh", "/etc/rc.d/init.d/jbossas7", "restart", "login" };
