I have a java interface to do data conversion, and a GUI in C++ to connect
to Oracle Express Server and through this GUI, I can run Express commands,
like loading an .txt data file (which I can got using Java interface) into
an Express DB. Now I'd like to call that GUI (in .exe file) from java interface
so that after data conversion, I can input them into a DB directly. If it's
possible? if so, how to realize that?

Thank you. Look forward to hearing from you.
