The function you seek Should look into ActionForward avaialable from Struts
http://struts.apache.org/api/org/apache/struts/action/ActionForward.html
But then again this J2EE so I would assume this would be off-topic?

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.
