linux, windows difference

[Rajagopalan Srinivasan <ra...@gmail.com>]

all

I have a simple program using pdfbox reproduced below. When I run it under
Ubuntu it creates the expected pdf file. On windows however I get a 3 page
empty pdf file. when I step thru code, it appears to be working ok.

Any ideas?

if it matters, I do have Adobe Acrobat installed on my windows machine.

package lister;
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.pdmodel.font.*;
import org.apache.pdfbox.pdmodel.common.PDRectangle;

import org.apache.fontbox.util.*;

        }

    }

        page.setMediaBox(pageFormat);

        try
        {
           PDPageContentStream contentStream = new PDPageContentStream(doc,
page);
           contentStream.beginText();
           contentStream.setFont( font, 12 );

           int lines= 0;
