Re: [DataVision-users] Problem exporting DataVision reports to pdf from jsp page

[Frank W. Z. <fz...@om...>]

Have a look at this article I wrote some time ago:

http://omnytex.com/articles/

It shows how to stream a Datavision-generated PDF back to the client. 
Note that you need to do this from a servlet because you will likely run
into those "response already committed"-type problems if you try and do
this from a JSP (it might work, I don't know for sure, but architecturally
speaking it's a bad idea anyway).
