Need Some Help
Hi All;
Trying to get a FOP demo off the ground. The idea is an FO document comes in
from memory and is rendered to a PDF on the hard disk of the server.
Just to get things going I am working with a FO file on the hard drive as
well. I will tackle the contents of this file submitted in memory next.
Below is my code.
When I run it in IE it get a Pop up message telling me the "File does not
begin with '%PDF-'". This is weird to me because I am not trying to send it
back through the response object, I don't know why the browser is even
looking at it.
When I run it in FireFox I get my success message printed, and the document
created. However when I trying and open it I am told there is a Sharing
Violation. The writer was closed before I printed the success statement so I
am not sure where the conflict came from.
Is there a better, smarter or easier way to do this? Any help would be
appreciated.
Thanks,
Luke

I set "file:///C:\fop-0.20.5\msmincho.xml" in userconfig.xml.
And this made creation of PDF in shift_jis through servlet, which
in fact, I had given up making one.(it is one of FAQ?!!)
you helped me great, thank you.

Are you using relative URLs in userconfig.xml? If yes, you need to set
the baseDir/baseURL (or fontBaseDir, if it is different from baseDir)
accordingly. The other possibility is to use absolute paths or URLs.

If you mean:

new Options(userConfigFile);
...then, yes.

Responding to myself.
I have found the problem, this code below works. I am still interested if
anyone knows better way to do this.

Hi;
Thanks for the response. I fixed the problem. Had the OutputStream still
opened. I responded to my previous question myself with the new functioning
code.
I guess the forum (or my mail server) is slow.
My new issue is how to render the PDF with a string input containing the
contents of the FO file.

Does the URL which invokes the servlet end in .pdf? IEx is easily
fooled, especially in absence of a content-type header.
Try to use an URL which ends in .htm or .html, or explicitely set
the content type to text/html, or both.

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
