Hi
Thank you for your kind reply.
Sorry that my code was incomplete, I have attached a fuller version to
this message.
I am using 2.0.0 .
When you say "PrepareFile is never constructed " . The constructor is in
the file or am I missing something?
Kind Regards
Gerry

Hi,
Assuming that you are using 1.8.10, use the PDFReader command line
application to check that PDFbox 1.8.10 can display your file.
The code you attached is incomplete. The imports and (probably) the
line "public class pdfViewer extends JFrame {" is missing.
PrepareFile is never constructed. (Maybe that too, is in the missing
lines - maybe some static code?)

Hi
I am trying to get a pdf file to display using pdfbox.
I can only get a plain box.
I am not sure what I am doing wrong, I have attached the two files to
this email, please forgive me if I have got something wrong I am just
a beginner.
Any help gratefully received.
Gerry
