Why does my application close when done ??

Question

I am running my application from a DOS shortcut which in turn executes the following .bat file :
Set CLASSPATH=C:\jdk1.3.1\bin
set CLASSPATH=%CLASSPATH%;c:\jdk1.3.1\bin;C:\source
c:\jdk1.3.1\bin\javaw -classpath %classpath% GradesGUI
The application comes up fine, but once the user executes the program (via pressing a SEND button), it closes the application, I am not sure what is causing this ?

Answer 1

I think I found out the problem I had the following line as part of my SEND button listener :
try {
Process p = Runtime.getRuntime().exec(message);
} catch (IOException d){
System.out.println("Error = " + d);
This seemed to close the window after I pressed SEND.
But I took out the Process p = part as follows :
Runtime.getRuntime().exec(message);
and it worked, but not sure why
