I've searched a lot but could not solve this problem. I am generating PDF files with iText. If i use FileOutputStream everything is fine but when i try to use ServletOutputStream the images does not appear in PDF files.
When I open the PDF file with text editor, i saw that there "???" so much. That means something is shaving the bytes. It is like trying to use binary files with JSP. But i am using JSF, Tomcat 6.0, Spring 3.0 and Richfaces.
Here is the code that generates PDF with ServletOutputStream and causes problem
And here is the code works fine with FileOutputStream()
I could not find why the bytes are being shaved.
Thanks a lot for your help,

Here is the solution that worked fine. Thanks to BalusC on stackoverflow.
When taking the response fully in your hands in JSF, you need to ensure that you call
before you set the headers, there is namely little chance that there's already something been set/written on the response (more than often by some sort of custom Filter).
You also need to ensure that you call
instead of out.flush() to prevent that any other bytes will be written to the response body afterwards.
Finally, in JSF you need to call
to prevent that JSF will forward the request/response to a view (render the response).
