I wrote something up on this a while ago ... there's some new information added to the Wiki.
http://webware.colorstudy.net/twiki/bin/view/Webware/PdfCreationWithReportLab001 It explains how to get the result you want. If you have any more questions please let me know ... I've been doing this with WebWare / Zope for the past few months so I've run into almost all the problems ( I hope! ;D ) Here's the statements I add to my servlets in WebWare / Zope. container.REQUEST.RESPONSE.setHeader("Content-type:","application/pdf") container.REQUEST.RESPONSE.setHeader("Content-disposition:","attachment; filename=rptWoOpen.pdf") It seems that the Content-disposition one is the key.
