Why does my program run differently under window command and Jbuilder

Could somebody please suggest me:

Why does my program run differently under window command and Jbuilder
some operations can not work when running in command.
They are using the same JDK.

thanks

Off my head, I'd say that you have set some run-time parameters in JBuilder that are
not specified when you run it from a cmd shell.

What operations are not working ?

thanks.

In a GUI I save something into a file and load the file again, they work on Jbuilder but not in command.

thanks.

sjalle,

I got it now. It took me nearly a day to get it.
I ran the program in different directories.

thanks.
