i though it would be a better idea to specify what will hgappend if source is dispenser instead of saying what if the shooter is not a ploayer. any ideas?

Not tested but try adding this after you check if the thrown entity is a snowball

  else if (projectile.matches("Snowball") || projectile.matches("Arrow") && !(shooter instanceof Player)) {
	  Location location = event.getEntity().getLocation();
      event.getEntity().remove();
      event.getEntity().getWorld().createExplosion(location, spow+.0F);
    }

I already done this, but all i want is if the source is not player make arrow un-explosive.
so i have to skip "event.getEntity().getWorld().createExplosion(location, spow+.0F);" from your code, Thanks ill let you know if it worked
