Hi,
I see you've already discovered it yourself, but here's a bit more info on
why I think it went wrong...

It may be weird, but it does point out one serious mistake:
> //get the content
> String pdfFileContent = out.toString();
PDF is not 'just text', so it's wrong to use a String to represent it. That
is not to say a PDF can't be opened in a text-editor --it can, but changing
a character and saving can seriously muck up the binary portions of the
file... not to mention prepend it with UTF-garbage.
The error message is Acrobat's IE-plugin complaining, and refers to the PDF
specification. A PDF file is supposed to start with:
%PDF-{version-number}
followed by a few (three or four... will have to look that up :-)) non-text
bytes.
These latter bytes will become 'characters' when you pass them through a
String, so the end-result is likely a corrupt PDF file, even if you're not
trying to display it.

Well... I don't fully agree. Keep in mind that in your initial code, the
physical PDF-file was referenced (for read/write access) by three different
objects: one File, and an OutputStream and a FileWriter wrapped around that
File. Only the latter of the three explicitly closed, which may have caused
the conflict to occur.
Open a PDF for writing in Acrobat, ask FOP to render that PDF and you'll
receive an error. Open it in Adobe Reader, ask FOP again, and it might work,
since the first handle on the file is read-only. (Since I tried the first
only on Windows, the latter only on Mac, this phenomenon could as well be
OS-dependent.)
Greetz,
Andreas
