Re: Text extraction - Any tutorials?

[Stephen Haggai]

Hello,

I too tried to extract text from a PDF file but I keep getting these
errors though the text seems to be fully extracted (not verified
though).

My code:

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\invoice.pdf");
         File output = new File("C:\\SampleText.txt");
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         //pd.save("new.pdf");
         PDFTextStripper stripper = new PDFTextStripper();
         //String text = stripper.getText(pd);
         wr = new BufferedWriter(new OutputStreamWriter(new
FileOutputStream(output)));
         stripper.writeText(pd, wr);
         //System.out.println(text);
         if (pd != null) {
             pd.close();
         }
 } catch (Exception e){
         e.printStackTrace();
                }
        }
}

The "error' or message that I get is

Is my code wrong somewhere?
