Why can't you just modify the servlet that runs the unix script to copy
the output back to the client after the script executes?
If the second servlet needs to perform modifications in the output format
(such as converting static text into HTML, or performing an XSLT
transformation on an XML file), that's the kind of things that a Filter is
for. Search Google and java.sun.com for "filter" and you'll find lots of
tutorials, resources, and examples of how to build such a thing.
