Execute another program with argument from java

Hello, I'm using Greenfoot on Mac OSX as user interface to open another program (the program is called CLIPS expert system). I'm able to do it with the following code:
?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
public void act()
{
   if (Greenfoot.mouseClicked (this))
      {
         try
            {      
               Process process = Runtime.getRuntime().exec("open -a clips");
            }
          catch (Exception ex)
             {
                ex.printStackTrace();
             }
      }
}
But I also want to pass an argument in the form of a batch file (entitled "runfile.txt") so that when CLIPS opens, I want it to automatically execute the commands I've written in the batch file (such as loading a construct from a file, resetting, running, and exiting CLIPS). I tried the following code but it did not do anything:
?

public void act()
{
   if (Greenfoot.mouseClicked (this))
      {
         try
            {      
               Process process = Runtime.getRuntime().exec("open -a clips -f runfile.txt");
            }
          catch (Exception ex)
             {
                ex.printStackTrace();
             }
      }
}
Additionally, I tried the following code and it did not do anything either:

public void act()
{
   if (Greenfoot.mouseClicked (this))
      {
         try
            {      
               String[] cmdArray = new String[2];
               cmdArray[0] = "open -a clips";
               cmdArray[1] = "batch runfile.txt";
               Process process = Runtime.getRuntime().exec(cmdArray)
            }
          catch (Exception ex)
             {
                ex.printStackTrace();
             }
      }
}
Does anyone know how to code what I'm trying to accomplish? Thanks, Vic
