Hi there !
I am trying to execute some O.S. commands from JAVA program. Here is my requirement ....
I am workin on WinNT 4.0; and have Oracle installed on my workstation.
>From command line I am able to export a particular database as

        c:\orant\bin\exp72.exe user/passwd_at_db owner=usr

The same command I want to execute from a Java program; and I am having problems. When i run the attached program; it just waits forever.

Hope somebody has some answer/clue to my problem.

TIA. Leo
