It is my understanding that some viewers only work right if you can set the content length. To do this you have to write the PDF to an internal ByteArrayOutputStream first to get the total length, set the content length and then write the resulting byte[] to the output stream.

I noticed you have asked the same question in the JSP forum. Anyone who wants to help should go to this thread.
Please don't post the same question in multiple forums. It creates duplicate conversations and wastes the time of the people who are trying to help you.
Don't get me started about those stupid light bulbs.
