I added all the imports for the program on the stackoverflow page so you
can see where the row variable comes from. Also, the reason I know it
happens on that line is I step over the code line by line in the
NetBeans debugger, and the error happens right after stepping over
table.draw();

This should not be a problem, as the default constructor looks like this:
public PDPage() {
this(PDRectangle.LETTER);
}
So there is a mediabox. But there are other problems too, I can't see
where the 'row' variable has declared.
And yet we did not see a stack trace. But probably this has nothing to
do with pdfbox nor boxable...

Tárgy: AW: CORS error when running PDFBox from a web app
Hi,
at your code at stackoverflow i noticed, you are trying to get the
mediabox without setting it before. I'm not very experieced in
PdfBox, but maybe it would help to use a different constructor for
PDPage:
PDPage page = new PDPage(PDRectangle.A4);
Best regards,
Siegfried

Betreff: Re: CORS error when running PDFBox from a web app
Hi,
Sorry for the formatting issues. It didn't look like that mess when I
clicked Send.
I am aware of the many resources available on CORS issues. The problem
is there is too many. I was hoping someone could explain why the error
happens on the PDFBox BaseTable.draw() command, which would help narrow
the scope of the problem.
For an easy-to-read posting of this problem, see

Hi,
your mail is hard to read due to some obvious formatting issues.
However it isn't necessary at all.
It is a security issue. Simply search for "No
'Access-Control-Allow-Origin' header is present on the requested
resource". There are a lot of hints how to solve that issue depending
on your environment.
The described issue has nothing to do with PDFBox.
