Executing an Executable or Batch file in DOS/Unix Env. - Urgent Urgent.

Question

Hi there
We are currently using Oracle 8i with 9ias as the Application Server. I have a requirement where I should be executing a batch file or a executable on the local client system (from where the browser runs).
I have downloaded a script from Oracle Metalink which creates a class file. This class file enables me to create a executable or a batch file on to the local client machine. But does not allow me to execute it.
Can anyone kindly send me a script which enables me to execute a .exe file on the client machine.
Many thanks in advance.
