PDF file cannot be viewed from OA Framework page.

Question

Hi all,
I have developed an OA Framework page which shall present an XMLP report in pdf within the browser.
When I click on my menu item which opens the oa page, the Open file.. diaglog appears. When I open or save the file (and thereafter opening if) the following error appears: _Acrobat could not open [filename] because it is either not a supported file type or because the file has been damaged._
I can open the file if I go to the server and copies the output file to my own machine.
The error that i'm describing is happening on the server and NOT in my development environment. I cannot get it to work at all on my own machine.
Some facts:
JDeveloper 9i RUP7
XML Publisher 6.5.3
APPS 11.5.10 CU2
