Trouble opening file with Java to use with PDFBox
显示 更早的评论
I am trying to use the PDFBox library to read the contents of PDF files, but I can't seem to open any of the files in the correct format for PDFBox to use. I'm using the following code to open each document:
javaaddpath('...\pdfParseDemo\pdfbox-2.0.0.jar')
javaaddpath('...\FontBox-0.1.0\FontBox-0.1.0\lib\FontBox-0.1.0.jar')
pdfname = '...\example.pdf';
import java.io.*;
pdfdoc = org.apache.pdfbox.pdmodel.PDDocument; %Define a PDDocument object placeholder
pdfdoc.load(FileInputStream(pdfname)); %Load the PDF file
However, this seems to return an empty object. When I try to query any of the file's properties or contents, it always returns an empty or zero value. I suspect the problem is with how I'm opening the file, because I know PDFBox has been successfully used natively with Java in many cases. Unfortunately the documentation for interfacing with Matlab is very sparse, so I'm not sure what I should be doing differently. Is there some kind of weirdness with how Matlab handles Java file input calls?

Try wrapping your pdfname variable in a java.lang.String variable. This sometimes works:
pdfname = java.lang.String('...\example.pdf');
