[jboss-user] [JBoss Seam] - Seam PDF creation

Sat Jun 9 07:30:05 EDT 2007

Hi all,

I'm just investigating the Seam PDF generation features.. and have some difficulties:

#1. In FireFox I get:

        This XML file does not appear to have any style information associated with it. The document tree is shown below.
  |       
  | ?
  | 	<html>
  | ?
  | 	<head>
  | <meta http-equiv="Refresh" content="0; URL=seam-doc.seam?docId=1&conversationId=1"/>
  | </head>
  | <body/>
  | </html>

If I cut and paste the URL part (seam-doc.seam?docId=1&conversationId=1), then it displays the Pdf fine.

#2. In I.E the redirect happens fine, but then I get "IE cannot display the webpage" and the following in the log:
