Problem in displaying PDF using JSP

Question

I stream a PDF to the browser in my JSP. I set the content type in response header to "application/pdf".
The pdf gets displayed most of the times. Sometimes the browser displays some junk characters.
Need help in preventing the browser displaying these junk characters occassionally
Thanks,
Ramesh
