So if I understand it right what you're saying means that one "presentation"
servlet queries "business" servlet for a file. This "business" servlet returns
a file to the "presentation" servlet, which in turn send it to the user.

Is this right?

If that's the case, you better let the presentation "servlet" do a forward to
the "business" servlet.
