PDFBox | Crash on line: PDDocument.load(file)

Question

I have the following simplified code:

PDFTextStripper pdfStripper = new PDFTextStripper();
PDDocument doc;
String text = "";

try {
    File textFile = new File("C:/Users/user/Desktop/PDF-test.txt");
    doc = PDDocument.load(textFile);
    text = pdfStripper.getText(doc);
} finally {
   ...
}

...

PDPageContentStream content = new PDPageContentStream(doc, page);

content.setFont(font, 12);

content.beginText();
// Write to page using a text file
content.showText(text);
content.endText();
content.close();

The Problem

I get the following error: java.io.IOException: Error: End-of-File, expected line on the line:

doc = PDDocument.load(textFile); in the try block.

What I've Tried

I've tried these solutions but none have worked:

• org.apache.pdfbox.pdmodel.PDDocument does not load / read the PDF document

• How to extract text from a PDF file with Apache PDFBox

• https://www.javatpoint.com/pdfbox-reading-text

• https://issues.apache.org/jira/browse/PDFBOX-4443

• merge files gives error: End-of-File, expected line

• PDFBox IOException: End of File, expected line

Expected Results

I want to load the text file without error and display it as a PDF with PDFBox.

Answer 1

PDDocument.load expects a pdf file, not a txt file.

See javadoc of PDDocument: https://pdfbox.apache.org/docs/2.0.2/javadocs/org/apache/pdfbox/pdmodel/PDDocument.html#load(java.io.File)

Answer 2

In PDFBox 3.0, you have to use org.apache.pdfbox.Loader.loadPDF(new File(...))
