Servlet to handle html form and execute mulitple external program

[sonuses]

HI,
i have created a html form having a text field and submit button and i want to send a directory path,i want that my servlet should take this dir as argument and call a external perl script with the argument and execute the script and return a name of dir with the checkbox on same html page.
can we call multiple external programs in a servlet?

You're not calling multiple external prgrams are you?
Unless I misread that, you're just calling a Perl script?

Anyway, there's nothing to stop you launching multiple apps from the Servlet. There might be questions as to whether this is a good idea or not, but that's an architecture and design issue, not a straight technical one.
