PDF download in 3.1 fails with "could not open" error

Question

Just created a couple interactive reports and was truly dazzled by the functionality. But when I try to download to PDF, Acrobat Reader 8.1.1 errors with msg "... could not open <file> because it's either not a supported file type or because the file has been damaged...."
No problem with CSV download.
Is there some special Acrobat plugin that's needed?

Answer 1

Its true its not required, but the instructions for deploying the war file advise you to use enterprise manager console, which you won't have if you have just got XE or if you have installed a database without Enterprise manager.
Ideally we need a method of deploying the war file directly
Step 1: Installing the WAR file
Place the fop.war file (located in apex_install_directory/utlities/fop) in an accessible location on your local machine. You then follow the directions below or can view the process by running this viewlet.
Navigate to your OC4J Oracle Enterprise Manager Console eg: http://localhost:8888/em/
Select the Applications Tab
Select Deploy Button
On the "Deploy: Select Archive" page use the option "Archive is present on local host. Upload the archive to the server where Application Server Control is running." Use the file browse to select the fop.war file and click "Next" button
On the "Deploy: Application Attributes" page set the "Application Name" option to "fop" and clear the "Context Root " option and click "Next" Button
On the Deploy: Deployment Settings click the "Deploy" button Message was edited by:
