The code works fine. If you dump the ByteArrayOutputStream to a file, like
this...
FileOutputStream fos = new FileOutputStream("mynewdocument.pdf",false);
fos.write(bos.toByteArray());
fos.close();
...the pdf is just fine. Opening a new document is useless, but not harmful.
Your error is occurring with whatever you are doing with the
ByteArrayOutputStream. If you are running a servlet, all you have to do is
set the http headers, then write to the response OutputStream just like
this...
HttpServletResponse res.setContentType("application/pdf");
ServletOutputStream out = res.getOutputStream();
res.setBufferSize(bos.size());
res.setContentLength(bos.size());
bos.writeTo(out);
out.flush();
bos.close();
...easy peasy!
