Restricting directory access of a Process created using System.exec(..)

[ajay.todimala]

Folks,

I am writing a Java application to execute a program (C++/Java) by
using System.exec method.

Is it possible to restrict the process (that is created using
System.exec(...) method) that is executing
the program to grant access permissions (like read, write, execute, )
to only a particular directory
and revoke all access permissions to all other directories and files.

Please let me know if it is possible. If so how?
Thanks in advance,
Ajay.

Your question really has nothing to do with Java, and everything to do
with the operating system you use (which you neglected to specify).

Assuming a Unix-like system, you can do it with chroot, although you
might need to be root.
