You have to supply it to the routine when you call it within the job. When you supply it, you should do it as below.....

routines.YourRoutines.youRoutine(context.paramName)

You routine should not be called main.
In the example you were given, your routine may be something like this.
public void youRoutine(String paramName) {
System.out.println(paramName);
}

OK. At the moment, all your routine will do is print the path with the value of a "param" variable to the terminal. You need to change the signature of the routine to something like below....

public static void myRoutine(String param) {
    String   path = "/home/data/"+param ;
            System.out.println(path);
            }

This will be called like below....

Myroutine.myRoutine(context.paramName);

I assume that you just want the value to be printed to the terminal and you don't want to use the value in the job. If you want to use the value in the job, you need to have a method return other than "Void". Check out how to write methods in Java.
