i want to display a pdf inside of my jsf page.

i use a4j:mediaoutput for rendering. i tested my code with a jpg an everything was ok. but if i use pdf i only got an image like a broken link,although the pdf is written to the outputstream. i wrote a copy on filesystem which is ok.

here is the code
