Help with Runtime.exec()

[Jennifer Sohl]

Hello. I am launching a java app from within another java app.
Here is the code I am using to launch to app:

Process p = Runtime.getRuntime().exec("java com.storekraft.ord.CVOrderEntry " + customer + orderNo);  

When this runs, it brings up the app OK.
Now, when I add the lines of code to set the parameters in the main
method of the app being launched and try to run it, nothing happens.
Here is the main method of the app being launched:

public static void main(String[] args) {
// If I take these 3 lines out, the app launches.
// If I leave them in, it does nothing??
if(args.length > 0) {
custParm = args[0];
orderParm = args[1];
}
CVOrderEntry cvoe = new CVOrderEntry();
//Center the frame...
cvoe.setSize(765,750);
//Get the screen size..
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
//Get the size of the Frame...
Dimension s = cvoe.getSize();
//Subtract half the frame from half the screen to get
//the x and y coordinates of the upper left corner of the screen.
int x =  (d.width / 2) - (s.width / 2);
int y =  (d.height / 2) - (s.height / 2);
//Apply these calculations to the frame...
cvoe.setBounds(x, y, s.width, s.height);
cvoe.pack();
cvoe.setSize(765, 750);
cvoe.setResizable(false);
cvoe.setVisible(true);
}  

What am I doing wrong?
Thanks!

Process p = Runtime.getRuntime().exec("java com.storekraft.ord.CVOrderEntry " + customer +" "+ orderNo);

I tried your suggestion (Here's my code):

Process p = Runtime.getRuntime().exec("java com.storekraft.ord.CVOrderEntry " + customer +" "+ orderNo);  

and still nothing is coming up. Any other ideas?
Thanks!

Looks like there is some error
Add this

<font size="2"> 
System.out.println("Exit value:"+p.waitFor());
 </font>

If it prints 0 => the process runs fine
non-zero=>There is a error

I tried running a simliar program and it worked fine.

Jennifer,
I'm not sure that you'll be able to come up with a platform independent use of Runtime.getRuntime.exec() to run another Java application. I've read from more than one resource that its use is not recommended.
(I'm not sure that the following "solution" is necessarily a good idea, but you might want to try it out.) Perhaps invoking the main method just as if it were any ol' method will do the trick.

com.storekraft.ord.CVOrderEntry.main(new String[] {customer, orderNo});
